IMO synthetic oils should be recomended for each engine. if you want synthetic, mobil one isn't as good as it used to be. castrol synthetic is good. but if you want a really really good oil, attempt Royal Purple. it gives a stock 01 camaro nine whp with a simple oil change. it does that by decreasing friction in the motor. it'll also save you gas. don't believe me? look it up.
good luck, hope it assists.
