Oil compairson report
http://www.performanceoilnews.com/oi...nst_oils.shtml
a buddy of mine did his own oil test on a dyno
he said all of the "walmart" oils lost power as the oil temps went up
LE does not. its not synthetic so they can use a different additive package
I'm using the LE 1540 with good results so far
Zinc is very important when breaking in a flat tappet cam, and many of the oil companies are fazing it out of their oils.
There are oil additives like GM's EOS to put the zinc back in, but I'd like to know if there's a list of oils that stil have the zinc in it.

Mostly, because I can't figure out how they think the Amsoil was the best stuff. From their dyno results, Royal Purple and Mobil 1 (and a couple others) made better power and torque than the Amsoil stuff. Peak power for RP was 266.6, Mobil 1 0W-40 made 270.5, whereas Amsoil made 261.7. Seems like to me that running Mobil 1 would be the cheap way to pick up 9 hp. Whole lot less money that most people pay for a FIPK.....

), so if i can pick up 9hp in the process, awesome! Last edited by ChocoTaco369; Jul 25, 2006 at 08:05 AM.


. And all of the companies that send a 0w30/40 wt oil instead of the requested 20w50 look seem like pansies to me.
