After consulting the manual of my '93 I see GM recomends 'SG' rated oil. And after looking through my extensive stock on hand including kendal, valvoline, & castrol in various mulit & straight weights I see none of them are 'SG'. The 'SG' must be either a synthetic or synthetic blend - I haven't actually looked into it yet. But, regardless - I'm curious what everyone else is doing ? Are You following the recomendation and using the synthetic, or just using quality conventional oil & making frequent (3000 mile) changes ???
As a side note...I thought I better consult my manual for my '94 trans-am since it supposidly has the same motor. Sure enough, it calls for the same stuff. However, I've been running Valvoline 10-30 since I've had it , changing every 3,000 miles. The car had 5,000 miles when I bought it & has about 40,000 now with no problems so far....
Thoughts anyone ?
