I'm happy that you’re happy. Unfortunately, we typically do about a dozen or so oil changes on customer's Porsche’s a week, and our collected results (and UOA's) do not back up your experience, particularly when you look at the performance of the same grades of oil in the same cars over time. Mobil has reformulated several of their grades as many as three times over the last five years or so, and oil testing has shown the changes have not always been positive ones. Sure, in many cases the oil could still be considered "OK" after low miles; but with many customers going 7,500 to over 10,000 miles between changes, and the results look a lot different. Throw in DE's and/or AX's (particularly in hot weather), and the results began to look absolutely dismal. Yet the same raced/abused cars running a 10W-40 ACEA A3, B3, B4 full synthetic (not a Mobil product) continued to have great UOA's after 10,000 miles and a lot of track time..................

You'd have either check their websites for tech data sheets (assuming they have them which some do not), or visit a well stocked store and read the backs of some containers. Pay attention to the ACEA ratings rather than the API as ACEA requires the finished product to be tested in order to obtain ratings, while the API has shifted to a "self policing" and “component rating” mode since it became the public relations and marketing arm of the US industry rather than a watchdog............... You can find an ACEA "whitepaper" as a PDF file if you do a Google search, which will explain the meaning for their ratings system, which is very comprehensive.

JP,

from Mobil 1's site i see the following info:

Mobil 1 0W-40 meets key industry and car builder specifications for:

Mercedes MB 229.5
BMW Longlife 01

Porsche Approval List 2002
VW 502.00/505.00/503.01

GM-LL-A-025 (gasoline)
GM-LL-B-025 (diesel)

ACEA A3, B3/B4
API SM/CF



So it "says" it meets the ACEA A3, B3/B4 requirement, but you still don't recommend it?
I value your experience, so I am just trying to figure out what to get other than Mobil 1. Currently I am running Castrol Syntec 5w-40, which also says it meets the spec.

thanks.

So you're saying that the 5 weight in Syntec 5W40 isn't viscous enough to be recommended? (ie it's too much like 0W40?)

No, I'm saying that experience (and a lot of UOA's) has shown the 10W-40 to be better.......the 5w-40 is not bad, just not as good as the 10W-40.....
