What Race Oil do you trust?
 

Asking about Stocker Engines in this thread;
I have used Royal Purple 5w20 for the last few years. After being told time and again there are faster, better protecting oils out there, I'm now ready to look at some other avenues. What good experiences have you had with which companies?
I did try Redline 0-5 once also, it was faster than RP, but my particular engine smoked with it.
I know a bunch of guys preach the Joe Gibbs, but, I also know some of them supposedly said that their lifters wont pump up with it. True or False?

What's your opinions?

I've never had any oil related issues using Joe Gibbs XP0.
It is a few hundreths quicker for me than Mobil1 0W20.
Not sure if that is worth the extra cost$$$???

Wade, I have used Gibbs, but am back on RP. Gibbs zero weight, both times I have tried it, shined up a couple of rod bearings, and lost some teflon off my piston skirts. I'm not the only one here seeing that. RP never does that. Mine also picks up more on the track with zero weight ("Race9") RP than Gibbs. On the dyno RP zero weight was an instant 12hp over Gibbs breaking oil (BR30?) Never tested the two zero weight oils back-to- back on the dyno. I use RP 5W20 normally. Never tried Red Line.

I run CAM2 Blue Blood 0w30 all the time, double-enter at big money bracket races, am notoriously bad about warming up the car, and only change it a few times a year. Haven't even added up the runs... but it's a lot. Used with K&N oil filters.

It's not silly go-fast oil, but it is a good protectant, and very consistent, with little to no break-in time. Typically just as fast on the first run as the 10th or 40th.

I've been using Amsoil since 1999 and switched to their Dominator 5w-20 race oil when they came out with it a few years ago. Lots of zinc and have seen excellent wear characteristics. They have a variety of other viscosities to fit most needs.

No dyno comparisons yet, but I've had to turn down the idle a bit after draining a conventional break-in oil and adding their race synthetic.

The college I work at is getting an engine dyno this year. Hopefully I'll be able to have them do some comparisons as well as tuning.
