Hello all,
I'm new to this board so forgive me if i'm a bit dumb on what all the terms and numbers mean, but thats why i'm here. I'm a drag racer so this is what my questions to this topic will revolve around. I drag race a 78 Coupe Deville thats powered by a 511 c.i. Cadillac and runs 10.70's in the 1/4 in good air, its a purpose built motor, no street use, 13.4 to 1 comp, Eagle rods, Ross forged pistons, the block is filled up to about 2-3 inches of the deck. The main journals are 3.25" w/.003 clearence and the rod journals are 2.5" w/.0026 clearence. I have no oil cooler as of right now, and no oil temp guage, but i'm installing one soon. I shift @ 5700 and go through the traps @ 5900rpm. Here are a couple of question for you guys.......What type of synthetic oil should i use, racing synthetic oil or standard synthetic oil? I know that the racing oils have low detergent to help resist detonation and provide more base stocks , but i want my motor to stay clean, but also want really good wear protection. I have been using 40wt Red Line racing oil, but i might be switching to Amsoil's 20/50 series 2000. Also, which brand is better? What important things should i look for in an oil besides the HTHS number? I know i have quite a bit of learning to do about oil, i'm still tring to understand all the facts and what properties to look for in a superior synthetic oil, any help is welcome. Sorry about all the questions in one post.
