Amsoil is all marketing hype
It is not on the approved list
imo it is not as good as the Mobil
Their 'objective lab tests' have no relavence to real world use and are crafted so the results favor their oil
Use at your own risk

you'ld be hard pressed to find a wear difference between these oils after a couple of 100k miles of use
getting oil hot and burning off contaminants and water is good
that is why short trips are a harder service duty on oils
much of it is placebo and preference
not saying changing is bad, but that there is nothing wrong with Mobil 1 and 'better' is subjective in this case, not objective
I would never use ANY oil not on the 229.5 list in our case (0W40 or 5W40 wt.)
do a cost analysis
cheaper to run Mobil 1 at 6k intervals vs 'other oil' at 10k?
Mobil 1 at 6k is going to be better than the others at 10k miles
Mobil 1 can be had at <$25 for 5 qts http://www.walmart.com/ip/Mobil-1-0W...Quart/23636902
if the other oil is $10/qt you can do 5k changes with the Mobil 1 vs. 10k with the other
which will be better?

^ This.
I really don't understand why some people bash Mobil 1. It's a very good oil, made by a reputable company that spends lots of $ on R&D, which is why it's OEM fill on Aston-Martin, McLaren, Porsche and MB AMG among others. Companies like Amsoil and Royal Purple may make a decent oil for some boutique applications, but the M156 engine is IMHO not one of them. Stick to 229.5 approved oils of the proper viscosity.
And, for those people complaining about valve lifter noise, low oil pressure and what not - if you are having these issues with any approved oil for your engine, chances are that your engine is worn, not that the oil is inadequate. Running a different or thicker oil may mask the symptoms, but the real problem is not with the oil but rather the state of your motor.

BMW calculates change interval this way when resetting the oil service:
miles to next oil change = 666 x avg. mpg from previous reset
if you average 20 mpg (driving easy in an e46 M3) interval = 13,300 miles
if driven hard and say 14 mpg ~ 9300 miles til next change
I'd say 7-8k changes for our car is fine as long as a good mix of highway/town
if mostly highway the 10k is fine
if mostly city/town I'd do 5-6k
but to each there own

is it that simple on the later cars? dealers always add the comment to the mix that the car also monitors moisture and temps to factor oil life. I didn't know it was as simple as monitoring only how hard you drive the car via MPG.

I think all the moisture/temp stuff is not true
Mpg would be proportional to temp
The harder you drive the higher the temp the lower the mpg and hence interval

Nobody here old enough to drive 10 years ago?
All 1998-2004 Mercedes used "FSS" (Flexible Service System). It was quite sophisticated.
https://mbworld.org/forums/10427-post3.html
It was dropped because engines sludged up from old oil, dealers didn't get compensated when they changed oil and the FSS disagreed and ultimately because MB got sued for engine damage claims. They switched to 13,000/1 year intervals (except for AMG) and finally 10,000/1 year for all cars.
What goes around comes around.

Speaking of oil, I am booked in for service this weekend....they said they will use Mobil 1 0W40 for the car. Is that the accurate type of oil for our cars?
Thanks
Thanks

Yes it is, and IMHO better than the Formula M 5W40 for all parts of your engine except the catalytic converters.

Okay great thanks for the reply. I wasn't sure if 0W40 was the right type to go with. It's an Indie shop that works on high end cars as well so I figured they knew what they were saying but I wanted to clarify. My cluster shows 15 days till service a0 is due, but I am getting it done this weekend.

If it's on this page, it's fine. If not, you're taking a chance.

The book says 229.5. Not 229.3. Not 229.51.

Correct regarding the 229.5 spec, but the second statement is not entirely correct. For the C63, it also has to be 0W40 or 5W40, which excludes all the 0W30 and 5W30 oils on the 229.5 page.

Mobil 1 0W40 exceeds both the old 229.3 and the current 229.5 spec and is on the approved list. It is fine both from a mechanical as well as a warranty perspective.

Edit:
Never mind. Just found it in the maint. booklet. That should really go in the owner's manual too. Thanks. It also says 229.51 is ok, where the owner's manual says it's not.

Yup - look at the approved oil spec for the M156 engine, footnote 2 in the sheet at http://bevo.mercedes-benz.com/downlo...Spec_223_2.pdf.

Yep. You don't mess around with a footnote that says "und."
And to make matters even weirder, that sheet says yes to 229.51 only for Europe, meaning it agrees no 229.51 like our owner's manual but not our maintenance booklet.
