Vavoline VR1 20W50 Racing Oil

I change my oil twice a year. I don't put enough miles on it,to warrant any more than that. I use VR1,and a bottle of Comp additive. OK,maybe it's not needed,but,those two bottles cost me about $22. I've got about $3500 in my motor. Seems like pretty cheap insurance to me. But hey,to each his own,do as you please.
