"Looking for an ENGINE OIL recommendation for my cam."
"Cam"...Interesting slang! In the movies, they always joke about having plenty of hand lotion around, but I've never heard them joke about lubing one's "cam" with engine oil. An amusing twist...
"When using our Hydraulic or Hi-Rev Series camshafts, always use a quality detergent oil clearly labeled MS-DG. This is particularly important when using hydraulic lifters as detergent oil prevents the varnish build-up which can cause sticking in hydraulic lifters. Detergent oil is used in all new automobiles equipped with hydraulic lifters and is available at all service stations. With our Hi-Rev and Roller tappet camshafts, a racing grade of non-detergent oil is preferable because of its improved lubricating properties at high engine speeds."

"Engine Oil: What Engine Oil and Lubricants should I use? Crane Cams does not recommend the use of synthetic oils during the initial break-in period for a new camshaft. Use a good quality grade of naturally formulated motor oil during this period. If you choose to use synthetic oil after the engine has been broken in, change the oil filter and follow the oil manufacturer's instructions. When using either regular oil or synthetic it is important to pick the weight oil that best matches your engine bearing clearances, the engine's operating temperature, and the climate the vehicle will be operating in. Use the oil manufacturer's recommendation to satisfy these conditions. Crane Cams offers lubricants to aid during the critical break-in procedure, and to prolong the engine's life."

"Some OEMs require the use of special oil additives for camshaft break-in. Although this is not necessary with the proper use of Cam Guard, they can be added if desired. Other oil additives should not be added until after break-in is complete."
