Personally, I'd run 10W-30 or atleast 5W-30. nothing thinner than that in the summer heat on a performance oriented engine. I always ran 10W-30 in my LS1's even though they called for 5W-30. Hope this helps.

Mobil1, but I like Amsoil even better.

I would stay away from Quakerbake, A good conventional is Valvoline or Castrol
And when I had my 2001 GT I ran 10W-30, It never got the 5w-20 that Ford recomends for that car. Its just to damn hot pretty much year round in Houston for that thin of oil.
