Brad Penn
 

Several well-known high end oil system and camshaft manufacturers (grinders) highly recommend Brad Penn, especially for nitrous, blower, and alcohol applications. A good indication of a characteristic desired for racing oil is its ability to adhere to rotating parts while providing an excellent layer of lubrication. If you doubt the quality and advantages of this oil, do yourself a favor and talk to users of Brad Penn oil.

Yes they have some but they have had to lower the amount of Zinc and phosphorus because it clogs catalytic converters. I won't recommend Brad Penn oil for a street/dragcar. Brad Penn works best in a engine with alcohol or nitros, since the oil doesn't mix easily with fuel.

well i ran the mobil 1 diesle oil in my truck for a while cause it was free but then a switched to 5w30 wight with lucas industrial additive for the extra weight

After switching to Brad Penn oil in my motor I will not use anything else. I swear buy it. It's not an alchohol motor just sunoco race fuel

a lot of people at the track that run 10s or faster use brad penn,like i said it keeps its slipperyness when contaminated...................................... .....any nitrous or blower guys listening in here!!!

Ive always used the valvoline vr-1,milks up fast but remains slippery, regardless,your still getting alcohol into the engine whatever brand oil your using,proper maintnance is key.I will give penn a try tho..

Didn't read the whole thread.... BUT...

Current Brad Penn is the old Kendell. Kendell was the bomb until they removed all of the good zinc and other additives from it.

Once they removed them, Kendell became garbage.

Brad Penn and Valvoline VR-1 are of about the same quality, with the Valvoline milking a little more with an improper alky tune.

I buy the Valvoline when I can't find BP.

If your milkin the oil using either brand your still going to have to change it at the same interval or run a hi oil, alcohol level in your engine,I mean its like an overfill condition,which isnt good....

most of the serious guys here run roller cams.we dont care as much(key words being "as much") about the zinc and phosporous content as the slipperyness properties when oil is used in a blown or nitrous environment. i understand that u know this already,just some might not

You should care. That slipperyness saves your rod/main bearings, lifter bores, push rod ends, etc etc. It does a little more than just protect your cam lobes.
