Oil FAQ
I'm not sure it this is the correct place for this, but my interest in it is because the LT1 requires synthetic oil.

it doesn't require synthetic oil... it is highly recommended because of the amount of 'abuse' synthetic oil can endure without breaking down like the conventional stuff. You can run conventional oil and not experience a problem, but why ¢ pinch now on a car that deserves the best???
Interesting info btw!!!

In 92 when GM launched the LT1, they did away with the oil cooler found in previous Vettes. This along with higher operating temps required for emissions lead GM to requiring synthetic oil as it would not break down like dino oil does at high temps.

As Strick said, it is also my understanding that GM decided on synthetic oil because they could do away with the oil cooler -- saved money and room.

Another reason they run from the factory with Mobil 1 is that the build tolerances for the LT1/4 engines are much tighter than the previous L98 engine, otherwise they would probably leak more oil sooner.

Some old and outdated information there. New formulations are hitting the market as we speak (type). The new GF-4, SM oils are just now being introduced, and it will make older oils obsolete.
And FWIW, there is an oil out there better than Mobil 1 for the LT-1/4 guys. Castrol Syntec 0w30 that is made in Germany. Check the back of the label of origin of manufacture. You can usually find it at Autozone. Check BobIsTheOilGuy website for more info.

This way, Mobil can put in their ads, "The only oil that GM felt is good enough for the new Corvette." Or, "The only oil that meets the exacting requirements of Porsche, in their 911 Turbo."
It's all marketing. All the synthetics at the top end of the food chain, be it Mobil 1, Valvoline Synpower, Castrol Syntec, Pennzoil... Just to name a few, all meet the same requirements of the US Petrolium whomever that sets these standards (I can't remember their name).
In short, you can't go wrong with any of them.

Currently, the only readily available Group IV/V oils are Mobil 1 and the made-in-Germany Castrol Syntec. All other "synthetics" are primarily Group III. There are some speciality Group IV/V oils such as Redline, Royal Purple, Amsoil, etc. But those typically have to be mail ordered.
Having said that, a well formulated Group III can perform as well as a poorly formulated Group IV. So don't get too hung up on Group numbers. The important thing is to look at the back of the bottle and see if it meets your requirement.
