I will be the first one to say that I run my car pretty hard. I want to do everything in my power to keep my car running awesome like it does now. Before i start doing my mods what are the things that would be the best things to do to help my baby out?? Like should I switch to Amsoil from Mobile, change my fuel filter, change my tranny fluid and rear diff fluid to amsoil?? I have 24k miles on my car. I change my mobile every 3000 miles. Thanks for your help.
