I run the same identical stuff as The #1 Top Mechanics do. And they choose Valvoline.


A local performance auto store that I got my Redline from only sold high end motor oils including Royal Purple, Redline and ....Valvoline [racing version]. A person who worked there said that all regular, name brand oils are made in the same production facilities except for Valvoline. Anyone know if this is correct?

Also, if someone uses synthetic, is it ok to switch back to dyno (several people have said not to)? If not, does the same apply to a blend?

I know, a lot of wasted time and money ... if I knew then what I know now....
