I have 6 QT of German Castrol 0W30 I have decided not to use in the Focus.
In a 1995 Buick LeSabre 3800 Series II V6 can I go from 10W-30 Havoline / 6 mo (4500 mi) changes to GC 0W-30 / 12 mo (9000 mi) changes?
I am plan on sampling the Havoline at the change to verify engine condition and then pulling a 6 month sample on the GC to check how its holding up.
These engines have a reputation for being very easy on oil.
