Old Oil

We have that down here, too. About time.

 

VR1 and VR1 synthetic are formulated for both racing and p***enger car use. Oil change intervals should probably be more often than with regular oil because of some (?) reduced additives, but should go much more than just 500 miles. If you can provide some proof of the 500 mile maximum interval, I would like to see it, as I've never seen or heard of any.

Valvoline Specialty Racing oil is for racing only, and not street legal.

 

Exactly....STP has always contained ZDDP and its only $3.00.
