Re: Engine Oil
 
CAM2 Blue Blood Racing Oil has over 2,000PPM Zinc, high phospherous, etc... everything you're looking for, and it's cheaper than some of the other synthetics. I run their 0w30 full synthetic... full time, too, and that includes double-entering at big money bracket races. In my opinion, it's more consistent in hot lap situations, where a 20w50 will start to thin out after so many heat cycles and make the car pick up. They also make some 15w30 and 20w50. cam2racing.com

We run the Lucas 20-50, change every 20-25 passes, and just pulled the engine apart. Bearings and everything else looks great.

Rock, Thanks for your comments.

OK, the consensus is to stay with oil that has a zinc compound in it. I switched over to Lucas oil this year as well. I agree that the cost of sythetic does not make it practical for my class. I stayed with the 20/50 grade and the oil pressure would vary from 40-50 psi pre race and 20 psi or so post race. Second question is would a thinner grade oil help. I have expierenced lifter failure twice recently, (80 runs between failures) both on the right bank. 2 & 4 cylinders. It made a mess of a lot of parts. Don't want to go through that again.

Thanks,

it ain't the oil, check your pushrod lenght and springs and also no oil restrictors

I also use the Valvoline VR1 race oil, it has ZDDP in it and states it on the back of the bottle.

Have to agree with Hitter.
Geometry or running wimpy valve springs and bouncing the valve train will beat a lifter to a premature death.
I ran175 passes on mine this year with a cam with .880" lift and seat pressure of 380#and well over 1000# over the nose.@7600 rpm......did not break any springs or even have to touch the adjustment more than 2 or 3 times. ..[ stud rockers and girdle too]
Anybody who knows me will attest to the fact that I am not shy about the burn out. ...but I am careful.
Read the Reher / Morrison article in the last Nat Dragster , some good reading there.
