Friend got the wrong oil and gave it to me, will it work?

Just my opinion but is it really worth risking damage to your engine to save $80??
Its really that bad.
Edit: Mann has no filter for the E55 but they do for other 2003 55 AMG models, would these work the same?

If you are going to have the engine running at high temps regularly then go for a more viscous oil.

If you are going to have the engine running at high temps regularly then go for a more viscous oil.
The recommended viscosity is 0w-40, so the cold viscosity is 0W, which will flow great, but you need the oil to have a higher viscosity at operating temperatures or you could have issues with your bearings and rings......

Based on my knowledge, the 0W 30 and 0W 40 don't flow the same at low temps. And even at high temps the 0W 30 will flow better and shall provide better lubrication. 0W 40 will only be a better choice if the car is to be driven at well above normal temps for a fairly long intervals of time.

0w-30 and 0w-40 have the same viscosity in cold temps. At operating temperatures, the 40w will be more viscous. On a high powered supercharged car, a thicker oil within the design specs is definitely a good idea. Not to mention that M1 0w-30 is already thin for a 30wt oil, when you add some fuel dilution and shear, you end up with a very thin oil.
If you are going to have the engine running at high temps regularly then go for a more viscous oil.
PS: 0-30, and 0-40 will BOTH flow at the same cold rate.




That said, I use the the 0W-40.

and guess what, those were usally the cars with lifter noise and oil consumption. Use only Mobil 1 0-40 or 5-40 formula m or ESP formula m. It will say on the bottle that it meets mb 229.51 spec. Other brands out there will meet spec as well just not sure which ones right now
