[QUOTE="JimIII@jdm, post: 15688247, member: 10902"] We use Valvoline VR1 10w-30 for break in (first 200-300 miles) then switch to 5w50 Motocraft. A good oil for racing and high power engines is Driven FR50, we use that in our Cobra Jet's. Amsoil or Mobile 1 are great too. I do not recommend Royal Purple it is too "slick". As with anything proper oil change maintenance is most important. So I do recommend changing the oil every 3,000 miles or if its a lightly driven car that won't get to the 3,000 mile mark that often every 4-6 months. [/QUOTE]
