[BiturboS4] Question re: 0W30 vs 5W50, both synthetic

[S Stiles]

I've been hearing bad things about the new (trisyn? supersyn?) Mobil1 0w30
in particular. In fact, Mercedes has just released a bulletin stating that
it's not approved for use in their cars.

IIRC there's a simple way to check whether it's OK for our cars. Be sure it
meets all of the specifications (not just weight) in our owners manual. I
believe it's the SJ spec that the new Mobil1 doesn't meet.

I'll dig up the article when I get a chance.

Note that I'm using this oil at the moment, and have noted that I'm running
significantly higher temperatures (~20deg) and am consuming more oil.

The oil everyone seems to be recommending at the moment, if you can find it,
is Mobil1 0w40, as it's still a "true" synthetic & meets all euro spec.
What's happening with their other oils is that they are starting to blend
w/Dino to decrease costs. Yes, you can no longer trust that Mobil1 is a full
synthetic oil.

Scott.
