Re: Simple oil question?
Read the back of a Mobil 1 15-50 container. Contains high Zinc content for high performance engines. Bought at Wally-world for $26 for a 5 quart container. A lot cheaper than amsoil. My $.02 worth.

Re: Simple oil question?
There are a few other Mobil 1 flavors that might suffice (come close to the "magic 1200/1300 numbers) if the 15/50 is not available: See Mobil 1 Product guide.

Re: Simple oil question?
Wow...two really pervasive rumors in this thread.
1) Marvel Mystery oil "deposits" metal on camshaft lobes. A myth. 2) LT5s require engine oils with high zinc/phosphorous content Another myth. Insufficient ZDDP in engine oils is only an issue with flat tappet cams and pushrod valve gear. LT5 is OHC so 800 PPM phosphorous is plenty. The idea that you need an oil with 1000-1500-PPM phos or your engine will fail is ridiculous. Best oil to use in an LT5 for street high-performance and occasional tracking is an ester- or -mPAO based 10W30 synthetic. Such products are available from Gibbs Driven, Red Line, Amzoil and others and they'll all have 800-1100 phos which is plenty. Regular old Mobil One 10W30 is less expensive but, also, a good choice and it will have 600-800 PPM phos. if tracking the car all the time a 10W40 is better.
