Here is something new to me. We just did servicing on our M-Class and noticed on the check list for 2003 to 2010 Mercedes-Benz Flexible Service System that there is a note stating "oil change recommended every 5,000 to 6,500 miles". I looked back at my service records and the first record I have with this note is September, 2008.

I thought the FSS, under normal driving conditions, meant an oil change every 10,000+ miles, so this change is a surprise.

Re: MB Recommended Oil Change Interval

Jim, I agree. The recommended oil change interval for the early 1990's cars was 7,500 miles ... which I follow for our 4 MB vehicles. As I recall the FSS was likely to stretch oil changes out to 10,000 - 12,000 miles depending on your driving style and service conditions. Guess MBUSA is pushing for extra service business by reducing the recommended oil change interval. I know the service business at our local MB dealer has dropped off considerably. I can get a service appointment the next day if I want.

Re: MB Recommended Oil Change Interval

I would suggest following your own oil change schedule.

How and where you drive all have an influence on how often you should be changing your oil. If you're driving consistently in the city, you should be changing your oil more often. Highway driving, it's acceptable to be taking your oil to a higher mileage.

Whatever the case, if you plan on running your oils for a higher mileage, at the very least, change out the oil filters midway. Your car will thank you for it in the long run.

Re: MB Recommended Oil Change Interval

I don't know whether the recommended oil interval cited is accurate, or if it's a change from practices in the past, but I wonder if a shorter than standard oil change interval -- my C55 seems to have started out with something like 12k miles between changes -- on the M-Series may have to do with an expectation that these vehicles get harder use -- carrying loads, driving in low-low gears, towing trailers -- than the standard M-B vehicle.
Just a speculation.

On my MY1998 W210, the reset value for the FSS is 10K. Maximum is 20K. Most W210 owners get12K-14K. Minimum is 365 days.

I suspect FSS default varies by model/service. I agree dealers are encouraging more conservative service cycles especially on things like transmission service.

I thought it was 10,000 or so miles or one year as well. This is new to me as well.

Jim - is that 5 - 6000 mile recommendation actually in the MBUSA provided service manual or is that shown on a sheet from the dealer?

Re: MB Recommended Oil Change Interval

The maintenance manual and owner's manual state to make the oil changes at the FSS indications. This notation is on the checklist the dealer uses at the service and it appears to be an internal checklist. It would be interesting if all the dealerships are using something similar - with the notation.

Re: MB Recommended Oil Change Interval

Stick w/ the 5-6K interval, your engine internals will Thank you in the long run!

FWIW, you can have your mechanic/dealership change the parameters in SDS so that it calls for oil changes every 6K. We do as much with the FSS cars that are serviced here.

As these FSS cars age, I'm seeing more and more suffer from 2ndary air injection issues in the heads, manly the passages loading up with carbon. This is a MAJOR issue to remedy and one that could have been prevented with more frequent oil change intervals.

Never mind the general wear and teat/sludging I see on these extended drains.

the simple mantra to keep in mind, the fluid in X system is Always cheaper then replacing said system should the fluid no longer provide adequate protection!

Re: MB Recommended Oil Change Interval

I obviously don't see the number of cars you do, but IMO changing the oil twice as often as the manufacturer recommends is a waste of money and resources unless an oil analysis tells you that the oil needs to be changed that often. Under normal circumstances, there is no way anyone can just look at the oil and tell that it is time to change it. One could ask the question if 5000 mile oil changes are better than 10,000 oil changes, wouldn't 2500 mile oil changes be even better? I change my oil according to the manufacturer's recommendations with occasional oil analyses to confirm my intervals. That would be every 5000 miles using dino oil on my 240D that I've owned since new (350,0000 miles) and 10,000 miles on my E300D.

Re: MB Recommended Oil Change Interval

I would like to see if Mercedes-Benz is recommending the 5 - 6,500 interval or if this is a dealer recommendation. I too have trusted the engineering of the engine and follow the manufacturer's recommendation.

Has anyone seen any literature, like a TSB, about this?

Re: MB Recommended Oil Change Interval

From what you said, it sure sounds like a dealer ploy to drum up business. Doesn't your owners manual tell you what the interval is when the service indicator is reset?

Re: MB Recommended Oil Change Interval

I base it on my observations of what occurs to the engine internals, primarily the build up of Sludge, the incidence of noisy lifters and the previously mentioned clogging of 2ndary air injection.

Mercedes went from being one of the most maintenance intensive cars on the planet, with strict schedules that made most every other manufacture look Lax.

During the 90's Mercedes changed their focus from building the Best car they could to building disposable automobiles, they also started to include free service for the first 30K to compete w/ other manufactures. @ this point items became, sealed for life, oil changes 2X as long..systems that called for regular maintenance now became maintenance free seemingly overnight.

When I take apart an engine I can tell in a matter of minutes if the oil has been changed Often and Regularly.
My machinist who has been re-manufacturing Mercedes engines etc for all the dealers in the tri state area for 25+ years holds the same opinion, in that the current set of recommendations are unacceptable if long term viability and optimal operation of ones engine are sought after.

But, with that, it's not my car and people are free to change their oil as they see fit..:surrender:

What you fail to take into account is the switch from regular oils to fully synthetic oils like Mobil 1 which occurred during the same time frame.

MB has nothing to gain by taking a risk with the engine. Even the marketing people know that. In the three years I've have been visiting MB sites I don't recall a single post regarding a badly sludged engine. Given the subset of posters (those with problems) I doubt it is an issue. And the vast majority are using FSS defaults.

But I agree with you that people should be free to use whatever service cycle they see fit. It's their car and their money.:grin:

Re: MB Recommended Oil Change Interval

How many owners are opening their M112's/M113's?? Not many...but I do a LOT of valve cover gaskets and I see the Mess that these extended drain intervals leave behind.

It's simple, bring in two cars w/ 75K, the fellow that has changed every 5-6K, inside his engine looks Beautiful, clean, no etching/wear on the lobes..beautiful. The fellow doing the 12-13K changes, there will be a significant build up of sludge and Any metal surface that experiences wear/friction will show wear.

Oil changes are Cheap, do I throw away "good" oil, prolly..but it's Cheap insurance IMHO, and my only out of pocket cost is parts when things go awry!

If you don't trust Mercedes to specify an optimal service interval, why would you buy the car?

Re: MB Recommended Oil Change Interval

The vehicle we just had serviced is a 2008 ML320 CDI. Len, the owner's manual does not specify an exact mileage interval for oil changes, it specifies that when the FSS indicates a change is needed to do the change. The interval can vary depending on driving conditions. I have had 12,000+ mile intervals and have had in the range of 10,000 miles on the vehicles I've owned under the FSS system. However, the maintenance manual has 10,000 mile intervals for service, of which our latest was the 40,000 mile service.

I haven't been able yet to find out if this 5,000 to 6,500 mile oil change recommendation is from M-B or if it is a dealer thing.

One of my personal rules, and it applies more stringently the more expensive something is, is that I generally don't do business with people whom I do not trust.

As far as real world experience, don't you think Mercedes would have more than you do?

Moreover, I think your anecdotal evidence is sketchy, with all respect. I've removed many valvecovers on BMW M30s to do the valve adjustment. BMW used to specify a 7500 mile oil change with dino oil -- and dino oil from the 1980s and 1990s was junk compared to dino oil we have today (outside of the additive package, which was more robust and suited to these motors). Never any build-up, sludge, etc. But you claim a 10k mile / 1 year oil change interval (that's what Mercedes specifies in the newer cars and in our E350) on cars that use 8 or 9 quarts on average of high quality Mobil 1 synthetic are going to see signficant sludge? Not buying it, with all respect. Lubrication technology is vastly improved comared to where it was 10 or 20 years ago. Changing oil every 3k or 5k miles in these cars is a waste of time and money, and it is creates needless waste oil.

At the end of the day, it is a free country. Do what you want to do, obviously. But it seems illogical to me to spend all this money on something when you don't trust the people building it. Maybe that's just me.

While there is nothing like personal experience in real world conditions, we can't all experience everything on our own skin. Life is just not that long. So we must rely on the experience of others and trust what they tell us. With some practice, we eventually get to know who is telling the truth.

If M-B tells me to change my oil at 10k and that turns out to be wrong because my engine wears out prematurely, M-B will eventually lose my business. So they have gained nothing and lost by misinforming me.

On the other hand, if you tell me to change my oil at 5k and that turns out to be wrong, or unnecessary because oil change intervals of twice that mileage work just as well, you won't lose my business because my car won't suffer, and my wallet won't even feel it. So you've gained by misinforming me.

Who then stands to lose more by misinforming me, M-B or you? Is M-B so dumb and stupid as to take the risk of misinforming me and depending on me not to find out the truth eventually? Don't they intend to stay in business?

That's why I'll take my chances with the information printed in the Owner's Manual, before I take the word of someone who has something to gain by offering information that is contrary to the manufacturer's recommendations.

Picking and choosing which recommendations by the manufacturer to follow doesn't seem wise. In this case it's merely a matter of some additional inconvenience (the trip to the shop) and a few extra dollars (cost of the oil.) But in other cases it could hurt.

When one comes to distrust the manufacturer's recommendations it's time to turn to another brand, which's recommendations one can trust. Distrusting everyone's recommendations and testing them all by oneself to learn which are correct is not a practical option.

Re: MB Recommended Oil Change Interval

I change it at 5k with synthetic..

I am currently at little over 1k and need to change it due to massive amounts of short trips and cold shutdowns etc.

I pity people that listen to the manufacturers. You do realize their intervals are pushed to the maximum possible that will not destroy the engine during the warranty/lease period? Also lots of people dont want to spend 40$ on oil so to them it is just great if they don't have to do that at all...

Re: MB Recommended Oil Change Interval

If you change your oil at 5000 miles without doing an oil analysis, you have no way of knowing whether it is needed or not. It likely isn't. I was very apprehensive about going 10,000 miles between oil changes on my 210 diesel. I did an oil analysis at 5000 miles and one at 10,000 miles and the difference in the numbers were insignificant - I could go even longer. That convinced me not to waste money and resources doing them earlier. I am pretty confident in the fact that I don't know more than the engineers at Mercedes and with the backing of science, I think I proved it.

Re: MB Recommended Oil Change Interval

An interesting note in Car and Driver in the test of the BMW 5-Series against two other sedans. In one of the sidebars, they noted that when BMW went to the paid-maintenance guarantee for all services done during the warranty period, the oil chance interval miraculously lengthened. C and D noted that their BMW was showing 14,000 miles and still hadn't asked to have its oil changed.

Another note: how often you change the oil depends a lot on how you use the car. I take my C55 out on the track (as I did with my Dinan Mini before it) and everyone agrees that I should change my oil every 5,000 miles because of the hard use. On the other hand, if you drive a long highway commute every day and don't do a lot of jack-rabbit starts, you might easily go 15,000 miles between changes with a new engine and synthetic oil without doing any harm.

Bottom line: There is no hard-and-fast rule; it depends on how you use the car, and if you're really compulsive about car care, invest in oil analysis before you just decide to be ultra-careful and change the oil more frequently than the manual suggests.

Hmmm....never done an oil analysis. After driving 1.5 million miles, I never had an engine problem either. Still, the oil analysis sounds kinda fun.

What is the best/easiest/least expensive way to get one done from the Atlanta area (or the third world postal delivery country)?:tongue:

I was very apprehensive about going 10,000 miles between oil changes on my 210 diesel. I did an oil analysis at 5000 miles and one at 10,000 miles and the difference in the numbers were insignificant - I could go even longer. That convinced me not to waste money and resources doing them earlier. I am pretty confident in the fact that I don't know more than the engineers at Mercedes and with the backing of science, I think I proved it.

Analysis can vary. Say i test it this month, it comes back acceptable. Next month i drive differently or the weather changes. Suddenly it is no longer a good enough lubricant.

If the MB engineers were worth their salary, we wouldn't have failed oilers, tensioners, chain guides, seals at under 100k. That convinced me they really don't know much beyond rolling something off the assembly line :)

Hmmm....never done an oil analysis. After driving 1.5 million miles, I never had an engine problem either. Still, the oil analysis sounds kinda fun.

What is the best/easiest/least expensive way to get one done from the Atlanta area (or the third world postal delivery country)?:tongue:

These people. Your oil will appreciate it.

That sounds good... but can anyone post a copy of the test results and explain what we would be looking at?:Thumbs up:

I doubt if the results from two successive oil analyses are going to change with a month's worth of bad weather or even a track day or two. Typically, these are run every six months or one year on regularly driven cars, to spot both oil issues and potential engine problems.

The quote that parts of an engine shouldn't be failing at 100K miles is interesting to me. As a long-term gearhead, but only recently come to M-Bs, I was frankly amazed at the fact that there was a make of car where 100k miles wasn't the rule-of-thumb limit before a required engine rebuild. Even at 20,000 miles a year -- a higher-than-average amount -- that's five years before failure of any engine part when most U.S. and Japanese cars were assumed to be junk after five years (Japan won't certify a five-year-old car for use on the road). Seems as if Mercedes engineers have long been doing a better job than engineers in most of the rest of the world.

They are not failing (well except if your tensioner goes) but the tear and wear is beyond normal on certain (replaceable) components. That could have easily been fixed during design/testing stages at MB.

Even more to the point: why would you expect parts NOT to have "normal wear and tear" at 100,000 miles. I think your expectations may be just a tad unreasonable. Do you have a basis for comparison on some similar number of cars built by other manufacturers?

Re: MB Recommended Oil Change Interval

With the cars that receive Regular and for the sake of this thread Early/unnecessary oil changes the engine internals look just about New even with Very high mileage.

I remember our neighbor back in NY had a Buick 3800 V6. He changed his oil every 2500 miles like it was his religion. Finally @ 285K the rear main seal let go so he pulled the engine out and decided to go through and freshen everything..
Inside the engine looked as though someone had just run it through a hot tank, bearings looked beautiful, only the tiniest perceptible lip @ the top of the cylinders. It was nothing short of Impressive.

on 116's/17's and 19's I can pop the oil filler cap, look @ the wear on the cam and know if the PO was fanatical about oil changes or not...those that were have Beautiful cams, the others you can see the etching/wear marks showing up..

Granted, they never look as bad as a set of neglected lifters from an AH 3000, but still;-)

Because they are not normal TW on other engines?

I have japanese ones with over 200k. Friend has 324. Show me a single modern MB engine that can do 300k without having to have it open up for one reason or another and still perform to spec. No noises, no stutter, no idle issues nada.

Re: MB Recommended Oil Change Interval

I am old enough to remember the flathead Ford engines that were pretty much worn out at 40k miles. This was due to a combination of metallurgy, lubricants and engineering practices of the era.

I believe any modern engine, even in inexpensive oriental cars should go far over 100k miles without major work assuming good preventive maintenance practices and good fluid products are used. My neighbor has gotten over 400k miles out of an Oldsmobile of all things. He uses a synthetic oil not available in the usual stores. I'm not naming it since I don't want this to degenerate into an oil thread. I have been using the same product in all my engines including outboard motor and weed whacker.at his recommendation and have never had an engine or transmission wear issue.

Stretching the change interval consistent with driving conditions to the extent recommended my either the auto manufacturer or the lubricant manufacturer should be safe. If one wants to be extra cautious, you could change the filter at an interim interval. An oil analysis, in my opinion, is ultra @n@l unless one wants to use the system that the U.S. Navy does. They do not change oil until the periodic analysis says it is time. Using that method, most of us gearheads using a good synthetic would be surprised at how long between changes.

All that said, I confess to 6k mile changes.

Geez, stop the flames. If you want one example of Japanese engines (I experienced no less than 6), my Camry went to the boneyard with a bad engine at 250,000 miles. A second example was my Corolla which had to have the engine rebuilt at 3k.

By contrast, our ML is working on 300,000 miles with ZERO engine work and it is on it's original spark plugs.

It's a car, not a cult. Faults are corrected through exposure and complaints. Otherwise we would all be driving yugos and be happy, no?
Bring the ML, would love to see it. :Thumbs up:

With all respect, the 116/117 motors are not an appropriate analog because I doubt Mercedes specified a 10k mile / 1 year oil change interval. Different construction and finishing techniques, different lubricants. Same even with the 119s.

A quick story: our 740i is one of the BMWs that originally came with the Nikasil block. BMW, to its credit, changed the motor several times and we now have an Alusil block. No problems with it many years and miles later. But yet, being "old school" with car maintenance, I wanted to change the oil at 1k miles after the block replacement. Was told it was not necessary because the new blocks are micro-finished or polished, so there is no metal debris or similar when they are new. I didn't believe them because Roundel magazine's technical editor told me all BMWs need this oil change, and all other fluid changes, or the car will implode when it is out of warranty. So, for some reason, I gave the magazine technical editor more credence than BMW and went ahead and tested the oil at 1k miles. It came back as BMW said it would. I learned the lesson to stop wasting time and money second-guessing the manufacturer. If I had real reason to suspect they weren't being "straight" with me, the answer was to buy a different car. So far, following that advice with all are cars, whether they be MB's, Hondas, or BMWs, had led to cars that are reliable and well maintained and much less of a headache than the cars I owned 20 years ago. Why I, or anyone else, should be surprised that technology moves forwards and not backwards, is something that puzzles me.

I wonder if these same folks would ask to be treated with mid 1980s or mid 1990s medical technology if they got sick because that's better? Or if they watch TV on 1980s TVs or 1990s TVs and think the picture is better?

There is as much "religion" here as analysis, so I'll move along now. I would suggest to Gary that he do an article on this, but whatever he does with the article the folks that are disproven, one way or the other, won't believe it anyways so it is probably better to spend the pages on something else.

Because it is religion, there's no point in writing articles, technical or otherwise.

I've written my share, dealing with allegedly superior audio cables, during a 10-year period in the '80's. The results were unsatisfying, to say the least because people's strongly-held beliefs won't budge unless the hold on them is released. And the hold won't be released by applying reason, facts, or anecdotal evidence.

So we must deal here with people having strongly-held beliefs about some things, and just accept that this is how they feel. Fluid changing intervals in cars is one of those things.

Re: MB Recommended Oil Change Interval

Actually I was thinking that, since Hedary has already done an article on oils in older cars, and Murphy has done a number of articles on oil in newer cars, that I should shift my focus and do an article on whether some people are predestined to own Mercedes while others only achieve them through a lifetime of good works. Maybe a sidebar on whether the car can be fixed through the laying on of hands, if your faith is strong enough.

Re: MB Recommended Oil Change Interval

I can't speak about "laying on of hands", but I will provide some anecdotal info about my 1980 300SD (OM617 engine) and me...
Changed dyno oil and filter (MB/Henke/Mahle) every 2,500-3000 miles.
Autocrossed the "mistress" for 6 years, eight times a year. Yeah, I did have separate rims w/BFG R1 tires for track/autocross
Participated in StarFest '94, StarFest '96 (long drive from DC), and
GWS Tri-O-Rama every year.

Bought this fine car w/121kmiles. Finally got into the "GWS Groove" after much urging by great friends.. In 1998, I sold the car w/347,000 miles with original unopened engine, original Garrett Turbo, original injector pump, original injectors and replaced glow plugs when necessary. To quote Marshall Booth - Drive your diesel "like you stole it", and regularly do an "Italian tuneup".

Bottom line -Regardless of your car model, regular/synthetic oil and filter changes will significantly prolong the life of your Mercedes-Benz cars, whether diesel or gas..

Just my opinion.......:cheers:

Gary,

Your thinking is perfectly in tune with the modern age and the 21st Century. Shifting your focus onto an article, or a series even, dealing with car procurement and maintenance as a function of our hopes, fears and superstition would be a service to all.

The factual, reasonable and logical approaches have been done ad nauseum. We're really bored with all that stuff, and the truth might as well be relegated to previous ages. No one really wants to hear it, now that we have the internet.

What's in demand are solutions based on prayers, rumors, rants, and other clever essays - in other words, solutions based on the use of WORDS. Though some graphic or musical input might well apply.

While a lot of the preliminary research in this subject has already been done by manufacturers and sales organizations of snake oil products, they've only scratched the surface of this garguantuan and ripe-for-the-pickings field, as related to cars.

We M-B car owners, with our relatively deep pockets, are especially vulnerable to suggestion via words. Why, every time I reach for my wallet I hear plaintive words in my head - words like "You are crazy!"

It's quite possible that the sounds created in our minds, upon reading the sacred words in such an article as you propose, will resonate with our closely-held beliefs on the subject and allow the gradual release of such beliefs. It could happen.

You would be performing a true service to us all. I encourage your thinking. Please let me know how I can help.

Re: MB Recommended Oil Change Interval

Alex, sounds like an exorcism you're suggesting. Can't hurt to try to banish the narrow-minded, self-important evil spirits that live in some of our less open-minded friends here, but it seems like a tall order to lay on poor Gary. Still, Gary's observation in raising the theological angle here in the first place, gives hope that he might actually pull it off.

P.S. I'll be looking for the article.

Oil as a religion? No, thanks, never discuss religion or politics.:eek:

It does seem there is always a great divide amongst those discussing oil and it's many topics... but what would be accomplished with an article in The Star? I would be interested as always in what Gary comes up with!:Thumbs up:

With Alex's witty response, I think I've got some fodder for a small set of letters in the next Letters Column. BTW, I do hope you guys are biting your tongues off in your cheeks in writing these words.

And let's not even get started on three-in-one oil.
