I thought about listing the basic information in a separate thread so it would be easier to find when someone does a forum search, but I guess that isn't necessary.

I agree; how hard would it have been for the dealer to tell me this? On one phone call, the parts person did say that early on that he had attended a Mobil 1 meeting and complained that they (the dealers) needed a spec 229.5 oil and not just a spec 229.51. Seems to me the dealers would know first-hand that Mobil 1 did just that, and that there is no retail version, other than through Mercedes parts and service.

Anyway, I'm glad I finally got an answer that makes sense and I now know that there is in fact a 'Mobil 1 5w-40 Formula M' oil that exists and is approved for my non-diesel vehicle.

It's all out of a bigger picture to get more money from us! Promise! Even though 0w-40 is more expensive

Thanks for the thread and information Richard. My dealer changes my oil using Mobil1 Formula M 5W40 (no ESP) from their bulk tank and have for the last couple of years. I don't know if in the mean time they went to 0W40 and back again as suggested.

I went as far as contacting MBUSA when I thought they were using the ESP version. They called the dealer and got back to me that they are using the plain Formula M.

Coincidentally, my oil consumption was about 1 quart/750 miles running the 0W40 and it went down to 1 quart/2500 with the 5W40 so I am happy. I have since had my leaking valve covers replaced so consumption should drop even further.

Hope this helps.

I have a bottle of each sitting in front of me. The ESP Formula M has the 5W-40 with a green background and a green circle the the right with a vehicle icon in it. The Formula M has the 5W-40 with a black background and no circle. Formula M also has Official motor oil of NASCAR at the top.

I never saw the Formula M on the Mobil website either and I think that's because it is no longer available in quarts. They only sell it in bulk to MB dealers. I bought what I have over 2 years ago from a place called AVLubricants in Ohio. Customer service had a hard time locating it even then!

Hope this helps.

While I haven't been able to stop by the dealer, I was told that they do sell the 5w-40 by the quart at $7.50 per...

Musikmann

Take an empty oil bottle with you. At least at my dealer the last quart I bought from them came in a windshield washer fluid bottle.

ohlord

I was looking over the "stuff" I had left over from the car. Within my Owner's Manual package, I came across an informational graph that indicated which oils could be used in the car. It had 5 or 6 different oils weights listed - all based on the coldest start temperature your car would encounter. I'll try to take a picture of it and post it here tonight.

EDIT: nevermind... Ohlord is correct in that I wouldn't be adding any new information to this thread....

fits the bill for those temps.
The chart is on the mbusa site.

Now, lets switch to transmission fluid and rear gear oil!

Musikmann

If you are changing your own oil, as advised, look for Mobil1 0W-40 on sale and use that. If you have a dealer do it, you're stuck with Mobil1 5W-40. Either should be fine and meets the MB 229.5 spec.

I am burning significantly less oil running 5W-40 than I did when running 0W-40 so I'm sticking with that.

I vote for rear axle gear oil. where can you find MB Sheet 235.7 - Fuchs TITAN SINTOPOID FE ​​75W-85?

Dealer wants $69 liter for MB branded.

Musikmann

I found this but I don't see Fuchs mentioned. This is dated 2007 so might be too new for most of our applications, but I see 235.7 among the rest.

This thread is funny.

Dealers and shops can be wrong. Dealers (which are shops all the same and not arms of the MB corporation) do things for various reasons, usually revolving around money. It is entirely possible that a service manager at a shop or dealer with a GED and years of word of mouth from mechanics is wrong.

Do some research about what the different grades of oil actually mean and you won't have to lose so much sleep at night or ask so many questions.

5w-40 and 0w-40 are not all that different. furthermore, according to the MB manual, my e500 can take any grade from 0w-30 to 10, or even 15w-40, depending on climate and conditions.

you can be within specs, and correct, while using two different grades of oil. neither is wrong.

if you live in climates with a real winter, the 0w-40 is better, but if you live in arizona you can use 10-40 and have the same result... and no problems! you only need to worry about the spec# when choosing brand, IMO.

there is too much to be said about oil viscosity in one post... all you need to care about is the effect. with a 0w-xx oil you will probably burn more oil than you would otherwise but it will also be easier to start your car in the cold and the oil will be more fluid in the cold, thereby protecting your engine better than a thicker oil before the engine is warm. when the engine is warm the second number is all that matters. conversely, a 5w or 10w oil will be a little thicker when cold... but it has to be REALLY cold for there to be much difference between 0w and 5w.

Remember when all our W210 engines were brand new and ran in, the best that was out there was 229.3 spec!

229.5 will be FINE whatsoever! 0W-40 for Petrol, 5W-40 for Diesel

229.51 is for Diesels with a DPF (Diesel Particle Filter) and like ohlord said is also low ash and might be bad for the bearings in our over 10y/o engines.
