the single best oil we ever saw in service were the NEO synthetics sold by Baker in california. tolerance to heat was simply unbelieveable and in one case where the driver lost the belt on the dry sump while leading he ran the last two laps w/ zero oil pressure and won with the only damage being that the cam and lifters turned bright blue and there was the most minor bearing scuffing. when we ran the V-6 buicks in the 24 hrs of daytona, i remember taking the motors apart after 24 hours of non stop 8250 rpm racing and finding the bearings still had the pencil marks on them where i had noted the clearences and the rings had zero wear.

problem was the cost was outrageous and the shipping was impossible. the mobile 1 synthetics were cheap by comparison and off the shelf everywhere and were 99% as good. when the redline guys sponsored the drivers with oil and cash, we sold the oil for more cash , used the mobile 1 in the cars and ran the redline stickers as per the contracts.

we never tested or ran the amsoil simply because their hype turned me off so badly that it made me hate them without any good reason... and we were more than happy w/ the mobile 1 products anyway.

its what i run in the boat now...

My engines run cooler then other oils I have tried.


I have been using Redline High Performance Oil (Not to be confused with the Racing Oil that is detergent free,...as non-detergent oils are a bit more friction free)...

I have to say I am impressed with their oils and like their 2 stroke oil as well.

The flashpoint of 20W-50 is about the same as M-1's V-twin. V-Twin is about a "55"wt oil and Redline is about a "50 wt" oil based on cst's @ 100*C. Cost is about the same. I hear Autozone sells it as well.

They also make a 15W-50.


Anyone have experience with Redline to share?

Fyi..

I have been getting it in case lots form their online site.

I think the one thing I like about it most is that it stays "cleaner looking" on the dipstick vs. many other synthetics I have used.

This is a key point in this discussion, as most production-based engines (like boat engines) are designed with a generous margin on bearing area, piston ring widths/tension, etc. Purebred racing engines like Cosworth/Ilmor Indy engines, the racing Buick V6's, Formula One, etc. tend to be built to the very edge, where the oil's film strenghth and lubricity are all-important.

When we started running Mobil One in our CART program in 1990, we traded drums and cases of it to other teams in return for their other sponsors products (beer, mostly). I'm pretty sure that Mobil One was in the crankcase of almost every car in CART, regardless of whether or not it had a "Valvoline", "Shell", or whatever sticker on it. The Mobil guys knew it, and figured that they won almost twice as many races as they could legally claim!
