I wiped a *&^@$%#*^ lobe off my cam,

Rotella no longer has enough ZDDP in it. They changed it a year or so ago.

During cam break-in, you now need to use the special break-in additives as standard oil is no longer sufficient.

Not all racing oils contain enough additives for street engines. They usually
lack the proper detergents to keep things clean (race engine get torn down quite frequently with very little miles on them). Some of them dont contain enough ZDDP either. For example, Valvoline VR-1 only has about 1000-1100 PPM, which is borderline for a stock engine.

Too much ZDDP can be just as bad as not enough. Too little causes excessive wear. Too much causes metal spaulling.

Using ZDDP oil additives can be a real nightmare. First you have to know the PPM of the oil you are using. Then you need to know the PPM of the additive. Then you have to calculate the amount of additive you need in relation to that specific oil. Cant go too high or too low, or you cause problems. Topping off the oil when you need it is just as much a pain.

I switched to Brad Penn oil as well. It contains the proper amounts for regular engines as well as engines with bigger cams and higher spring pressures. Stock engines need around 1100-1200 PPM. Engines with higher spring pressures require around 1500 PPM. Brad Penn has 1500 PPM. Costs about the same as regular oil. No worry about getting the mixture right with additives. Just keep a bottle in your car and top of as needed. Always the correct amount of ZDDP.

I looked at all of the alternatives, and this was the best for me. I always keep a couple of cases on hand now.
