Just cause its not listed on that website doesn't mean its not produced. I use it everyday at work. Here is the data sheet from Mobil.

Mobil 1 5W-40
My dealer put the new ESP 5W-40 in my E63 last Summer, when it was HOT outside. I noticed from day 2 after that service there was a little audible lifter noise at initial startup, lasted about 30 - 60 seconds and then all was fine. Engine ran super once warmed up, and the oil lasted a long time without getting discolored much. The 5W-40 is a quality oil.
However, I did my customary 6 month oil change at home last month, used Mobil 1 0W-40, and cold start lifter noise is completely gone. Engine revs freer when cold, but once warm no perceptible difference in performance.
I say my 156 engine is happier with the 0W-40, while the cold start lifter tap was likely harmless, it was not there before the 5W-40, and is not there after it either.
I'm sticking with 0W-40 going forward. Have also always used the 0W-40 in my C55 and V12, never had any lubrication issues with either.

Using 0-40 Mobil, many people have reported similar positive experiences with other engines. Nice job.

I by the stuff every oil change at Oreilli's auto parts, it is a diesel motor oil so they sell it in 1 gallon jugs, we need 2 gallons anyway.
This oil should eliminate sludge buildup.
