I have a 2013 GT with a Kenne Bell supercharger and I was told to use Redline or Amsoil 5w50 only by my mechanic. What do you guys run?
x2i run the car year round on e85, blower car 600+ and use the dominator 10w30 amsoil.
If you run on the track, I would use the 5w50
Here's my favorite oil. http://www.bobistheoilguy.com/pennzoil-q-a/
