OK, since some of you guys can't read, I'll spell this out for you:
Valvoline makes 3 different racing oils.
1) VR-1, a conventional oil that is basically like any other passenger car oil in that it has an additive package based on calcium for detergent capabilities, as well as much higher levels of zinc and phosphorous to protect high revving solid lifter valvetrains.
2) Not street legal conventional racing oil - no detergents; meant to be changed very often in professional racing environments like drag racing using methanol.
3) Not street legal synthetic oil - no detergents; meant to be changed very often in professional racing environments like drag racing using methanol.
Wheeeeeeeeeeew, I hope that gets it!
So zoomzoom, it would be advisable NOT to use Valvoline's synthetic racing oil as it has a pure racing type additive package that has no detergents.
For your application, any quality synthetic would work fine. Is it synthetic or higher ZDDP, or both, that you're after?
