How many runs between changes? Thanks.

Always use VR1 10-30 on both cars! (Engine builder direction).

I don't change it often. I cut the filter open after each race. Guess it gets a new quart in the new filter each race. New oil about mid season. Clean oil, clean filters, I don't see the point of more often changes. May be why I don't see a pan full of crap like some discribe.

Dave Layer and myself were dyno'ing one afternoon over at his shop. I don't know how we missed it, but we made a complete 7800 rpm pull after the oil pump pic-up broke off on the previous pull. Embarrassing for both of us,. I don't know what we were looking at, but obviously not what we were supposed to be. The printout let us know we only had 5 lbs. of pressure the entire pull. We pulled all the caps, and the bearings looked like they had never been ran. Pretty unbelievable. The oil was Amsoil 10-30 Racing.

Did that improve the power at all ?

I looked up the sheets. Five horsepower. The pick-up broke on pull # 3 and the no oil pressure was pull was # 4. The short block had been broke in previously with a different set of heads. So oil temp might have been a little of that five horsepower. Dave's dyno did not register oil temp. Experienced dyno operators on here will know better than me
Man we sure do miss that guy ………..

A very well respected engine builder told me that on one occasion the customer told him to drain all the oil out of the SBC engine before the last pull, it picked up 8 HP and was still in one piece when disassembled for a freshen up......I won’t reveal his name but he was the mayor of a small city between Texas and Arkansas.....
..LOL. ,!!!
