Re: Oil Recommendations for Mild Racing Cleveland??
HI MATE,,penrite hpr 30 is a good oil to run for the cam brake in preiod and for the run in period too,,it has a high zinc content for flat tappet cams,,
some people drag race with it too.
Im assuming your doing circuit sprints,,I have been using castrol R 10w60 in my 350-370 hp clevo for a couple of years running in circuit sprint races and using it on the road as well,,have had no dramas with it at all,,good oil pressure hot and cold.
Ive run at phillip island a few times too and i dont think i would have had oil pressure on some of those long corners because im just running a std high energy sump not a circuit sump,,but engine held up fine, so id say the oil was doing its job.
weve used it in a customers car that i built the engine for 5 years ago that races nearly every weekend and drives to and from the event so its a good all round oil i think.
10/60 is a good range for cold hot running but id change it after every 3
Feed my will to feel this moment urging me to cross the line..
We'll ride the spiral to the end and may just go where no one's been...
