Best Race engine motor oil

[quadzjr]

I have always been an amsoil fan.. but it is a bit expensive. Most ofthe time we use mobil 1.

Ron, never heard of that oil.. it is hard to put faith into somethign new when so much is on the line. I assume it is what you use in the 2.3L?

The Valvoline VR Racing has some properties that make it attractive. It has the moly_____ lubircants amoung others that many don't have these days. I could be wrong, but I beleive it has kept the additives that most of the oils have dropped as of late. If you look around there are posts about newer oils that don't do such a good job of lubricating in return for fewer emissions.

Oil weight decisions has a lot to do w/ what the bearing tolerances are and what oil temps the engine sees.

First and most important question- Flat tappet cam, or roller followers? If its a nice modern piece, use nice modern oil, just like what the owners manual specifies. Its tough to go wrong with a synthetic that meets ACEA (European) ratings. (Read: Mobil 1) Then watch oil temps. You will do more damage running too hot, or starving the pump in high G situations than you ever will by running good synthetic 5W-30 in a modern IT engine. If its a flat tappet dinosaur the game changes.

But thats just my opinion, I could be wrong.

Redline holds consistent oil pressure in my engine better than any other. sold.

Thanks Guys! still looking for thoughts on best weight to run in average NE summer temps(65-90deg f).

Also, the Brad Penn oil that Ron mentioned would seem to be grat for older cars(HP,etc) as well as formula VEE's since it still has the zinc in it. I thingk Penzoil has a synthetic w/ the zinc still in it,too.

Any thoughts?

We run Redline 10-30 in the C cars in New England. Pressures stay good, 60-70 hot at race RPM, 20-30 hot at idle.

We did a lot of research on oils. From break in to running. Most of the off the shelf pep boys oils are missing some of the most important things a race motor needs. Trace elements like phosphorus, and zink are being removed from mobil 1 and others. Gibbs racing produces some very nice blends, royal and others are good also. The reason we run the Brad Penn is that it is a company taylored to racing. You can call them up and they will talk to you about what they are doing. Also talk to cam grinders and ring manufactures about what they would like to see in your oil. Don't just read online, make some calls and ask a few simple questions. You don't want to waste their time but many different companies were very forcomming in "oil" beleifs.

One last thing the Penn oil is very cost efective. I mean the same cost of mobil 1. And one more thing, it is US crude, not middle eastern. Not that matters, but you can buy something made in America.
