That's a good question. How do the rings get stuck? Roush wants the motor to run with very light weight
oil, 10w-30wt, conventional only. No
synthetic. I thought it might be a heat thing and my motor runs right at about 200 degrees
oil and about 210 degrees water. That is right on. I know that the FE/ alumn. big blocks run a little hotter. Mine is right where it is supposed to be. I've been going through a little
oil right from the start. Roush does run these wide open before you get them. I don't have the answer. It does run great though. I'll keep everyone up to date as I get the info. Good stuff to know.
