Valvoline VR1 20w-50w Racing Oil
Does anyone use this oil? If so, is it supposed to be red.

Clois,

VR-1 is no longer racing oil. They changed the color when they reformulated it to meet EPA regulations.

I now use Schaeffers.

Interesting little note I came across on the Comp Cams web site. Talking about the recent failure of MANY solid lifter cams from ALL manufacturers.

Turns out due to EPA concerns today's 'modern oils' are missing Zinc and Manganese. These ingredients are needed for camshaft break in. It HIGHLY recommended to use an additive, like the GM EOS, which DOES contain them. Especially during the cam break in period.

Now I'm thinking it's a good idea to use such an additive all the time? Bear in mind not all additives have Zinc and Manganese!

Elric is correct. I was recently told that Comp Cams has been doing a lot of testing with Shell Rotella-T 10/30w & 15/40w and has had excellent results, in particular with solid roller setups. I'm sure flat tappets would benefit just as much. The other real benefit to these types of oils along with zinc is the anti foaming properties which helps to keep the oil from sudsing up and becoming aerated at higher rpm.

Valvoline VR1 20w-50w Racing Oil i"m still using it.

Jerry - do you really expect everyone to read those links you post? The Readers Digest version would be more palatable

[Jerry Cowing]

Of course. I expect you to read every word. I'll be passing out a test later so you better study hard.

Readers Digest version = use Mobil 1 extended or AMSOIL.

Came across Schaeffer Racing Oil on a web site that was analyzing various synthetic oils and additives. Schaeffer 20W-50 rated very well. Schaeffer 7000 also has two friction modifiers, Moly and Penetro, to reduce engine wear. Schaeffer produces several specialty oils, some used by in large specialty earth moving equipment, which require very effective lubricants, as well as the Racing Oil having good success in Nascar motors. I ordered a case for my 302. www.schaefferoil.com Have fun.

Royal Purple 51 sounds like a good choice as well or Mobil 1 extended 15w/50.

I just ordered a case of the Amsoil 20w/50, Ouch!!!!
