If you go online you can see the actual testing of the oils, Brad penn, Joe gibbs, Mobil 1 racing oil etc. It seems that the Amsoil beats all of them pretty good. Those crates are low on power so you can run the real lite oil and make more HP. I used the Mobil 1 for years with no problem. When they dropped the racing oil a few years back we went to Amsoil. Mobil 1 is back with a racing formula now and they should be fine. They are all good oils, take your pick.

I bet if you look hard enough, Amsoil footed the bill for the test. I am not saying it is not good but Magazines and most on line test are VERY biased.Comment

Yes Ego, that was one of my buds that ran his engine on the dyno, ran it until mid-season, changed the filter and added a fresh quart of oil. Then ran it the rest of the season and then back on the dyno and still had the original oil in it. That's a little more than I would recommend, but he wanted to put it to a real test!
XP3 is what I recommend for the 602 engines and I will save you some money on the Gibbs oil. Don't forget the price increase coming May 5th!!! (Currently out of stock of the XP6 at the Gibbs warehouse.)Comment

Some of the testimg was done by Amsoil as you said, but not all. The results were the same though. I read an article with Joe Gibbs as to his opinion on on Mobil 1. He stated that he rated them second best, next to him. He also said that the reason that Amsoil is so good is because they get thier base stock through Mobil 1. He gets his through Citgo. A friend of mine swears by Brad Penn, and he pretty much dominates the NMCA world of nostalgia pro street as of late. If you just use a top name I think you will be fine. When I freshen up our engines the anti scuff coating is always still on the bearings. Race on guys! ;-)Comment

Are these engines you guys are talking about all wet sumps? What oil pans and pickups are you using? Do you have to use the factory supplied oil pan on a crate motor? Are you using accusumps?Comment

I use Mobil 1, 5-20 or 5-30 whatever the local store's have stock of. Change every 3 races. Which is about 300-400 laps on a 1/4 mile track.Comment
