Thanks Pat I feel better now I thought about using a heated oil stick to kept it warm. I run 112 oct. and use Rotella. My engine builder is a very good builder and has built several motors that run at our track and he said the other guys have had the same problem and he said the same thing to the other guys as you said run there engines alittle to get the heat up and we live in S.E. Ga and the humidity is killer down here. Pat I got another question about another engine but I'll start a new thread. Thanks again
