RESPONSE FROM CRANE CAMS FROM: JERRY CLAY, Lead Performance Consulant
RE: Super Lube 99003-1"it is recommended for break -in, it's not necessary after that". The break-in procedure has also changed. The engine needs to be run between 1500 and 3000RPM for 30 minutes. We recommend that you mark the pushrod, leave the valve cover loose, and when the engine starts, remove the valve cover and verify that all the pushrods are rotating and just as importantly they' re all rotating at about the same speed. Break in oils Shell Rotella T, Delo 400, Mobile Delvac, Pennzoil GT performance racing oil, Joe Gibbs Racing BR, and Brad Penn break-in oil. As for the three diesels oils listed any will do as long as they are not for new API CJ-4 category for late model diesels".
