I use VR1 Valvoline Racing Oil I thought about switching to Brad Penn but have had great luck with this oil.

Any synthetic oil, We use Royal Purple XPR 10W40 Racing oil in 90% of our engines using alcohol.
We have been doing a bunch of reading on the Joe Gibs racing oil, supposed to be the best on the market.

My drive line has about 5 degree angle coming into my tranny and good pinion angle is this to much angle to tranny.

Not sure on the pinion angle, I am not a driveline or chassis specialist.
As for the oil, we run 10w 40 and 10w30

Most times oil gets milky with alcohol is becuase tune is too rich.

Old Fashioned if you can find it C I -4 Grade 15-40 Fleet or Diesel oils work very well for anything except blown. Blown you need heavier oils.

In Chevrom RPM Dello it is called MUlti-Grade. Avoid the LE or Low Emmision. Shell Totella T if you can still find the CI-4 classification oil. Careful Shell is printing the CJ-4 to look like CI-4. The difference is that the J is combining with the C at the bottom but at the top is separeted. I found this with a magnigying glass after buying a buch of oil and it jsut didn't look right on the API symbol. NAPA also has good Fleet Oils. Remember it has to specify as API CI-4.

I agree, without a doubt........Brad Penn.

( And most camshaft grinders will agree with Brad Penn. In fact Schneider Racing Cams sends an information sheet with cams listing Brad Penn as a recommended oil)

Kendall used to be Brad Penn oil..now Kendall's formula has changed.
If you want the Good Old Kendall which is better it is Brad Penn oil.
(Correct me if I am wrong guys.)...

We run a Blown Alcohol Altered and use 20W50 Valvoline Racing Oil Part number 211 (versus the retail "Racing" oil). We run Federal Mogul competition bearings and have yet to have an engine problem due to oil issues. The motor is a 509 with a 14-71, 27lbs boost with significant cam. Rings are total seal gapless. We run hat & port injection (buzzard catcher). 2100Lbs car runs 7.10's @ 190 at 3330ft corrected altitude. Shift at 8000, launch at 4000. We purposely run rich and don't set it on kill (parts are expensive). We DO NOT get milky oil. The wash down of the oil due to alcohol is based on the whole combo in my opinion. Although there is a time when the horse power level calls for it to cushion bearing load, 50, 60 or even 70 weight oil is not needed for most people.

PS - We change the 11L (8 in the pan, 3 in the accusump) of oil every 12 passes.

Whoever said run synthetic, absolutley not in an alcohol engine, some synthetic oils have additives that react with alcohol and create it to subdue to a gel like form, I have had it happen to me with Mobil 1 synthetic on the dyno. Ever noticed a loss in oil pressure, change out the oil filter and the pressure comes back (most people blame the filter, immediately cut it open next time and you will find jelly-like oil) Very common on a fresh or new alcohol engine (fresh cyl walls, rings). Always run a fresh engine on gas for 20-30 minutes to seat rings. Then go to methanol/alcohol.
We recommend Brad Penn to our clients, but I will definitely give the Valvoline VR1 high remarks also.
If you are having milky oil issues, either your rings aren't sealed, cylinder walls are out of round, or the engine is just plain rich.

Fleet oil 15 w 40 having the API CI-4 Certification on the label.

Can be found in brands of Shell Rotella -T (Carefully read the API Spec)
Chevron RPM Dello (Carefully read the API Spec)
Exxon Fleet
Napa Fleet

If you are way rich nothing will keep it from going to milk. If you can tune it to at least 20 % rich and no more the oil will again look like oil. The closer you get on your tune the better the oil will look.

Get a good easily servicable filter like the Pure Power, keep the tune up right and you will be amazed at how many passes you can make on the same oil.

I just bought some of the Rotella T 15-40 weight it has the API CI-4 Spec on it. New to this oil was told it has alot more protective stuff in it that most other oils.
