Anyone run the German Castrol 0W-30 in their 3800 Series II ? The fanatics over at BITOG treat the stuff like it'* a religion. Lately I've been running Chevron 10W-30 in my LeSabre, and it Loves the stuff. I would spring for the GC 0W-30 only if I knew for sure it would work well in a 3800 Series II. Your opinions please.

i run 5W- 30 all year round.
117k and still runs good (does not use oil)

i see were neighbors.

What is the supposed advantage to the German Castrol?

Ehh, it'* kinda thin. 5W at the thinnest for me.

That does sound thin. I use 10W30 (no dinosaur juice here - synthetic only).
