Best Race engine motor oil

[BruceG]

Looking for your thoughts on the above. Mobil One, Redline, Royal purple? Redline has a single weight that acts like a multi.

Also, what weight is best for summer racing in New England.

Thanks for your thoughts,

Bruce

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.
