2006 Mercedes E350 4Matic (W211.087)
Mobil 1 0W-40 vs 5W-40

Many of the MB dealers are using the Mobil 1 5W-40 for the 2006 E350 4Matic (W211.087) gasoline engine, but this oil seems for the Diesel engine (MB spec 229.31/229.51). Is it fine to use this oil for a gasoline engine?

By the way, many of the independent German car specialist mechanic shops are using the Mobil 1 0W-40 for the same car, and this oil is for the gasoline engine (MB spec 229.3/229.5).

If the Mobil 1 5W-40 can be used for a gasoline engine without a problem, which oil between Mobil 1 0W-40 and 5W-40 would be more suitable for my 95000 mile run W211.087?

If you want to recommend any other engine oils, please let me know.

Thank you very much in advance.

Here is where the confusion happens. If you go into a parts store, they have Formula M 5w40 Mobil 1 "ESP." *NEVER* use the ESP version in a gasoline Mercedes. This product is for diesel cars. It is much weaker in additives, so it won't hold up over the long oil change interval. That particular site linked lists the ESP version as 229.5 but the ESP version is *NOT* 229.5, it is 229.51 (diesel spec).


Now, dealerships in the US have access to a Formula M 5w40 from Mobil 1 that is ok for gasoline cars. There is no ESP in its name and it meets 229.5. That is fine. You typically will not find this in auto parts stores in the US, virtually no one carries it but dealerships (mostly in drums but some sell it by quart too).

Mobil 1 0w40 is perfect. It meets 229.5 for Mercedes, plus Porsche's specs, VW, Audi, BMW, and Nissan GTR of all things.

I have looked at oil analysis of the gasoline version of 5w40 and 0w40. The 0w40 on paper looks richer in additives, it has a higher starting TBN too, which in theory means it will probably have more life left it in at the end of the oil change interval than the other product.

Overall, never use the ESP version of Formula M. The other one is ok. Mobil 1 0w40 is one of the best and can be found very cheap. It meets many specs and truly goes above and beyond the requirements. Also remember to never buy 229.51 spec for gas cars, 229.51 is for diesel cars. 229.5 is for gasoline cars.

Penske automotive associated dealerships use the Pennzoil Ultra Euro 5w40 now for most Mercedes oil changes. This oil is of an extremely high quality too and meets 229.5 plus other european specs including Ferrari.

Thank you so much for your clear explanation about the Mobil 1 5W-40 in the auto parts stores, mac911

I will keep using the Mobil 1 0W-40 for my car. If I have a chance, I will also try the Penske Ultra Euro 5W-40 you recommended.

Happy to share what I learned. And the Ultra Euro 5W40 is Pennzoil, penske are the dealerships that use it for service.

Amazon sells it. Normally 0w40 Mobil 1 can still be found cheaper though.

Yes, I use Mobile-One 0w40 in my w209.

I learned a few months ago that the local dealerships (Toronto) here have been using 5w40 for the oil changes. I have confirmed this with 2 dealerships here. Good that I do not change my oil there anymore.

I still buy 0w40 from the dealership and it is still available.

What city are you located? Probably US, Walmarts here (Toronto) do not have Mobile One.
