What engine oil to put in my SBF

[Caprimaniac]

Craig; we are talking 360 degree turns in the highest possible cornering speed in the shortest possible radius. And the pan is baffled & trapdoored.

Bobcowan has a point on the temperature VS brake down.

We have royal purple here, but the cost is not 7.95 for 1 quart, but 27.82$ So, it's an very expensive oil. I'll consider it...

What about DynoCat oils? New brand over here. US brand, as I understand.

They have something called Fusion RXS 15W-50; synthetic.. "For high performance & racing engines...."

And Supreme Classic GTR 20W-50. This one is mineral. And they state: "...for extreme load and high temperatures... Also for racing applications where a higher viscousity is needed."

Do they say that this mineral oil takes higher temperature (than their synthetic alternative) before the oil film brakes down?

I consider DynoCat because they are situated close to me, are reasonably priced & give great discounts. And why not go Tom's way and use mineral...?

(I'll go to Canton roadrace pan & pickup next year, if it all stays together.)
