My '90 was an L-98 car. (remember it was a big pile of parts) A small block Chevy does just fine on Castrol GTX. There is no need for synthetic with a quality oil. Now let the brow beating begin.
...just remember, Corvettes did fine on conventional oil for 40 years before they had synthetic. They also changed nothing inside the engine that made it a neccesity to run synthetic.
just my .02

Mobil 1 full synthetic 5w30, just like the manual recommends.
The L-98 is fine with dino oil, but at the temperatures the LT-engines run at, synthetic is cheap insurance (compared to a new engine...)

Synthetic is the way to go

Let me ask this question guys. What do your engines run at, temperature-wise? Mine runs at 180 degrees on a hot summer day. I'm asking because I honestly don't know, is this not normal for a C-4? I figure if the water temperature is normal, cylender head temp should be close as well. I'm just trying to gather info for future reference. Sorry to hi-jack the thread.
