6.99 a qt for Mobil 1 at auto zone.
If you are going to run the car really hard I would use RP.
If not stick with M1.

Well people are always gonna be new and this question will always be asked. They are both good. They both meet the Corvette requirement. You will see slightly cooler oil temps with royal purple. You cant go wrong with either one. Usually Mobil 1 is cheaper but if they are the same where you are get royal purple.

Royal Purple is better oil, but in my opinion is not worth the difference in cost for a street car. In my area RP is about $2 to $2.50 a qt more. If for some reason they were the same price I'd buy the RP.

Royal Purple definately has the edge on Mobil 1.

With the hugh profits posted by mobil/exxon i try to not buy any of their products.I use sunoco fuel and when its time to change the oil it will be one of the other reccommended oils not mobil1.I think mobil/exxon are a bunch of crooks.
