When Shell Oil CO. bought Pennzoil they change the formula to make it better with some different additives, a friend of mine who crew chiefs a winning SCCA spec. car told me about it around 15 yrs ago. Valvoline now has the exact same feel when rubbing it between my fingers and probably the exact same additives as Pennzoil used to make their race oil slicker with less resistance Valvoline VR oil is a lot easier for me to buy than Pennzoil racing oil also. I have seen power gain by running hotter oils or thinner oils, hence using the 10W30Wt now versus the 20W50 WT oils If Valvoline or Pennzoil offered a 5W10 racing oil I would use it I use 5W20 WT Valvoline in all of my hot street motors with zinc additives, if needed for the cam and lifters. Same weight oil on street roller cam motors with no additives I'm not completely sold on synthetic oils yet, maybe some day

This is a timely post for me. I have been running 20-50 VR-1 for a long time and my oil pressure was 80lbs hot. I have been trying some 10-30 while the weather is cold and I am not beating on the car as hard.
I believe that the 10-30 is a better choice for the engine. But since I have ran the 20-50 for years with no problems, I have been a bit hesitant to change.
But if it works for Cab, I'm in.
Master, again and still

Brad Penn for the bracket cars and street cars for me. The Heads up car uses Driven, by Joe Gibbs.

We ran Valvoline 10w30 racing oil for years. Switched to Amsoil and saw a big difference in the appearance of the parts when we did our winter freshen and in the trash coming out of the filter, which we looked at after every weekend-even with the oil restricted to the cam and the top end. Also went from changing oil every dozen runs to every 50 or so, based on the appearance and smell of the oil.
With the Amsoil, we tried different weights from 10w30 to 0w20. The oil pressure with the water thin stuff got to be a little concerning, so we settled on 10w30, rather than tighten up the clearances. Clearances and internal leaks have to be adjusted and/or fixed depending on which weight oil you are using.
If the results don't match the theory, change the theory.

I use Joe Gibbs 10W40 in my street/strip car but I just checked Summit's site and it looks like it went up to $9.49 a quart.

I think my message would be oil is not oil. Looks to me that some has more additives than others and pass testing with higher marks as well. My message is that the majority of oil discussions on here turn into big stinkin' piles of opinions without any empirical data to back them up. Oil, religion, politics... possibly The Big Three of things which can never be discussed objectively. I'll wait and see where this goes before I decide step back in here again.
