[DeTomaso] A presentation on race oil basics from Joe Biggs Oil

[Mad Dog Antenucci]

Dan- All,
   
  Forget solid lifters....I have a stock Pantera! ;-]>
   
      At any of the ORR or track events now my little 351C engine water and oil temps through the 2006 and 2007 seasons have NEVER seen more then 210F of oil temp at WOT and average closer to 200. It doesn't matter if I am  at Silver State and anyplace else in traffic. That is with no cooling fans and the water is averaging 190F and also may go to a max of 210F in ORR.
   
  Do you think I or any of my fellow List slackers need to pay the added $4-5 bucks a quart for a stock rebuilt engine if they are changing out the oil and filters after every race? 
   
  Come on now people...lets get real here.
   
  Okay I admit I have taller gears, oil mods and a Ron Davis CUP rad. ;-]>

Yes but only if they have at least 1200 PPM zinc (ZDDP). Passenger car
motor oils had approximately 1200 ppm zinc prior to 2001. In 2001, the zinc
was reduced to 1000 ppm and in 2005 reduced again to the current 800 ppm.
Diesel oils like Shell Rotella T with the CI-4 rating had 1400+ PPM (some
as high as 1600). You can only get Rotella T 15W-40 CI-4 in 55 gallon
drums now but CJ-4 version that's available in quart bottles is 1200 PPM
so still should be safe for flat tappets. Likewise, Mobil has Delvac 1
along with several other oils with 1200+ PPM:

Something like Mobil 1 Extended Life or Turbo Diesel oil would be good
for flat tappet cams. Kendall Super-D 3 Diesel Engine Oil supposedly has
1450 PPM:

Chevron Delo is another that would likely work, along with motorcylcle oils
like Mobil MX4T. A number of guys are using Valvoline VR1 but beware there
are a couple of versions of VR1, one of which is not suitable. You need to
be very careful with racing oils as some do not have the additive packages
required for a daily driver application and/or require more frequent change
intervals (some need to be changed every 500 miles).

Whatever you choose, stay away from the ILSAC GF-4 specification oils as
the phosphorus (zinc) levels for those oils must be less than 800 ppm.
