D Service Again? I just had it last year and I only have 29k on my car....
I only have 29k miles so far, but the car is an 05
Do all E55s have the "real" FSS system (w/ the oil monitor sensor)?? Can you guys enter into the menu still w/ the W211s?
The letter designations are really for the shop, if you ask me. They allow the techs to figure how long each service should take and a list of what's done, etc.. Plus it considers usage, driving conditions, etc., to determine what should be done (esp with the oil monitor systems.)
iirc, a D service is an A with brake fluid, too.
It's either time (not mileage) or somebody didn't reset the car last time it was serviced.
But we should be considering time ourselves (i.e., oil after one year even if it's under the mileage, etc..), imho.
Amsoil is also a Class IV PAO based synthetic (like M1) and here's what they say:
"Amsoil oils are fully synthetic oils that use PAO base stocks and the highest quality additives available. The high quality of Amsoil's products combined with the physical advantages enjoyed by all synthetic oils results in a motor oil that can protect your car's engine for a minimum of 12 months or 25,000 miles. Combine that with one of Amsoil's Absolute Efficiency oil filters, which can also be used for that same 12 months or 25,000 miles and you only have to change your oil once a year."
So, I do it once a year despite the mileage. btw, my car was sitting on the lot (a leftover 2009 E63) for close to a year before I bought it. MBUSA had the dealer change the oil for me free of charge. Of course, I realize the motor was barely used (driven just around the lot; not too good for it) and wasn't being driven enough.
Maybe the Mobil just wants to sell more oil aside form the already extended OCIs, and that's why they say they say one year.....
In the meantime, due to warranty I'm changing every year.
all synthetic oils results in a motor oil that can protect your car's engine for a minimum of 12 months or 25,000 miles. the key word is a minimum. not maximum.
the key word is minimum. not maximum. almost every new study shows good motor oil can last alot longer than we thought years ago as long as its taken care of. in the aerospace industry you send you oil for analysis not some arbitrary time. but it is cheap insurance if your worried. for now.

I just don't see what the point of stretching it far without knowing (i.e., I can wait for two years, but what if the UOA shows TBNs that are bad? Then I've been running it on weak sauce for how long?) So far my UOAs have been fine but I'll just stick to one year and 10k, since (as you say) it's cheap insurance.
