Brad Penn vs Joe Gibbs Oil

[fastback 427]

A couple years ago we took several oil samples to our local caterpillar dealer for testing. Cost 17$ per analysis. Going by memory the rotella had 1200 ppm zinc. The brad penn had 1300 and change. Well worth the money to check to sure. I've heard rotella lowered the zinc as well.

 Schaeffers for me  started out with Brad Penn 10/30 in my 331 sb switched to Schaeffers  7000 5/30 picked up .15  the next year I got a deal on some Gibbs xp3 picked up another .1 ran the same oil all summer, about sixty passes. on tear down at the end of the season I found almost no wear, the very large flat tappet cam looked great.  started 2015 with Brad Penn 10/30 in my new Dart 348, after break in and one pass I switched to Schaeffers 5/50  picked up almost .2  big difference in how it ran. like to try some xp3 just to see.

Could that .2 been due to weather conditions?

I run XP3 in my race car.  Bearings and flat tappet cam look great.  It's not cheap but it works.

Could that .2 been due to weather conditions? passes made within one hour of each other. in 2007 I took my 66 chevelle circle track car to Raceway Park for  a Saturday play day and sunday night race  with IMCA vintage series. I had ben running Kendall 20/50 brown oil, not green like it used to be. I got a case of brad Penn 20/50, this was the first time I had run it. the difference the way the motor ran was night and day. oil temp dropped about 50 degrees  300+ is not uncommon in wet sump circle track motors during a 30 lap race. best of all was the power gain.  some times oil makes a bog difference in the way motors run. I want to try Motul 300V next
