Yes, I believe it's true that 'Vettes came factory with Mobil 1 (or some brand of synthetic) and it's rumoured that SS's and WS6's came with it as well, although I've never read any solid proof of that.

However, just because it came with it, you don't have to run synthetic.........you can switch to dino oil without any problems.

Yes, have always used synthetic. If I had the money, I'd change the oil every month. If you're trying to save money, there's my "extended miles" oil if you don't want to change every 3000 miles.

Is it recommended to stop synthetic after 100,000? I know synth is smaller molecules and therefore finds the cracks very easily, but doesn't it also keep the seals in better condition?

I only change my oil once a year.
At the beginning of the season of driving, usually around the end of May.

I alway run Mobil 1 Syn.
I only put on about 1000K a summer though.

Make me wonder if it's worth even changing........

Yes.. SS Camaros (and I'd assume WS6's as well) came with synthetic oil. Or at least my 96 SS says in the "Z28 SS" handbook thing you get from SLP says it does.

I use Mobil 1... it costs a little more but you change is less and it protects more. So I could never find a reason not too.

Synthetic oil has advantages with very cold start ups, a lot of stop and go driving, and for very hot climates where you're engine temperature runs hot for extended perods of time like in stop and go traffic.

I do not plan to stop using synthetic and my engine is just past the century mark,, I am using the Mobil One higher Mileage 100% synthetic.

Oh yeah don't use any oil additives regular oil changes is the very best thing for any engine.

no its true, says in the SS book thing, and says on the SS sicker, and says on the SS options paper.

I put M1 in my car jsut cause its not that much more.

My thinking is "old school" I like to change oil every 3000 miles so I dont think synthetic is needed in my case. I have also been told that on high mile engines synthetic oil can leak past old seals a lot easier.
