Switching oil brands due to reduced zinc. Thought I'd try the Valvoline vr1.
I seem to recall that at one time there were 2 different VR1 oils. One for off road only and the other was what was readily available in the parts stores. I think they had 2 different color bottles. Is this still the case or is there just the one now? If they still make 2 versions which would you use in a street/strip type application that has a flat tappet cam and is probably only driven a couple hundred miles a year?

Thanks
