Re: What Race Oil do you trust?
I just started using the Amsoil Dominator Racing 10W30 this weekend after finishing with the break-in oil, Brad-Penn 30W. I've noticed that the oil pressure has increased over the conventional oil, so much that I may have to go to a 5W20 to keep the pressure down. I'll know more after the first change when I can compare each oil.

This year I've mainly ran Valvoline 10-30 Vr1 conventional oil with great results. I cut apart my filter every 25 runs and saw hardly any material. 190+ runs so far this year changing it every 25 to 30 runs because it loses so much oil due to low ring tension (my fault).
Last year I used Royal Purple XPR 0-10 and it too worked awesome changing it every 50+ runs. 210+ runs last year on the engine and the bearings looked almost perfect. On top of that the Royal purple is a tenth faster in my engine. Both oils are awesome and I recommend them to all* *455 Pontiac Stock Eliminator Engine - The highest RPM it sees is 6100 |

Insiders with NASCAR teams tell me the Joe Gibbs oil does not get along with some of the various coatings, especially some of the DLC coatings. Having a DLC coating failure is catastrophic. We saw a measurable HP loss with Valvoline 10W-30 race oil, compared to the thickest Joe Gibbs break in oil. |
Re: What Race Oil do you trust?
I saw zero advantage to the Gibbs oil, never had bearing problems with anything else anyway. Did not like the sludge in the pan and oil filter, nor the loss of coating on the piston skirts. Some people love it. Had zero issues with RP, and "Race9" is the fastest I've found, so have changed back to RP 5 W 20 & the 009 for heads-ups. With no sludge, no wear, and fastest I have found, I see no reason to change. What is another oil going to do better?
Actually had zero problems with Mobile1 with Comp Cams break in additive added. |
Re: What Race Oil do you trust?
We also use Mobil 1 with the Comp Cams break in additive with no sludge or wear issues.

Re: What Race Oil do you trust?
I've been told that sludge is part of the oil that just "fell out of suspension". Not really sludge. (It is very slippery) And that it "mixes back up when running".
Don't care, don't want it in the bottom of my pan. I still break mine in with BR30, but drain it right after running it. Don't allow it to sit and seperate, if the BR30 even does that. Have not tried to find out if it does. |

Re: What Race Oil do you trust?
There was a good post on speedtalk a while back about VR1, and a guy on there who
is a independent oil analist/engineer tested 50 top oils for lack of wear #1 ding ding ding Pennzoil Platinum, then amsoil dominator then lucas racing oil!!! Now with real world racing experience i will say there are quite a few oils that perform well for anti wear that are not fast but will keep your stuff alive. As far as fast oils you got Royal purple, Red line Gibbs, Lucas and im sure some others, one thing i tried that was reasonably fast was using 4qts of kendall conventional 5/20 with 16oz of lucas breakin additive. I have used some of the other high ranked anti wear oils with good success for keeping stuff alive but performance suffered considerably, i can say for sure that there is a solid .15 to .20 from best to worst. |
Re: What Race Oil do you trust?
I had the same, grey sludge with the RP 5w20, both the reg and XPR, didnt matter. It never would "mix" back in. When we first built the car and were hammering on the engine, we had it out often and found the same thing everytime. I would clean in out completely and find it again the next time.
Good discussion guys, what have some of the rest of you found? I know the Gibbs is common in SS, any lifter pump up issues with the thinner weights in Stock? Wade |
