GC in a 3.8 Buick Turbo

[rhi]

Group,

I've previously used Mobil 1 10W-30 in my 1987 Buick GN with the 3.8 liter turbo motor. I don't race the car, and it's a "toy" so it only gets used about 1k miles per year (although when it's out, I make sure to get it well warmed up). The car is 90% stock and I change the oil about every 2 years.

What do you think of GC for this application ?

Thanks,
Rich

I'm not too easy about the 2 years thing, but GC seems like a good match for the turbo. If you never really get into it, something cheaper would probably be fine too.

I'd stick with the GC..

GC should do just as fine as the M1.

What the heck is GC?

In North America "GC" = German Castrol = Castrol Syntec 0W30 with "Made in Germany" on the back...

EDIT: Here is the FAQ GC FAQ (a sticky at the top of the GC forum)

I think two years is just fine, in fact I bet it could go 3 or even 4 with no problem. I did a two year/7600 mile interval with GC in my mom's VW and it did just fine.

The oil filter doesn't liquify after that much time??? Wow...

Nope, in fact the OEM VW filter says right on it 2 years/30,000 km.

What Patman said. I have a VW TDI also, and the filters are rated for 2 years/30 kKm.

Thanks for the input, guys. Sounds like GC with a Delco PF-52 will work just fine for the 2 years/~2k mile OCI I'm anticipating. I'll probably pull a sample for UOA after that and see what shape the oil is in. Since I'm doubting I'll see much in the way of wear metals with this OCI, what parameter would you guys use as an indicator of remaining oil life ? TBN ?

TBN is definitely one thing to look at, as well as the level of insolubles and the amount of fuel present. What lab will you be using for the UOA?
