I use Amsoil in my new camaro and all my other vehicles. It is the best oil on the market and will out perform royal purple and mobil 1 any day. I am a dealer of it but i am not hyping it up just b/c of that. I first started using it and seen the benefits and results of it then decided to become a certified dealer. check it out on my website
