There is a lot to oil....Then theres alot of myth`s about oil....I bought a cam from a fellow forum member several years ago 1 lob was worn (Not Round Yet) all the other lobes had the correct wear pattern and even the lifter for the worn lobe looked mint...I miked all the lobes 15 were in spec 1 was worn .016 on the nose...on the worn lobe it still had the correct tapper to spin the lifter and keep the cam held in the block.....Is it possible the cam was ground this way??? I have bought worse cams from Comp before...

After carefully reading this and all the other oil-related threads on this site and the rest of the internet, I've made major changes to my oil system.
Behind my rear seat, I've mounted a 55-gallon drum of a mixture of new oil composed of 1 quart from all available retail brands, plumbed directly to the oil pump pickup through an assembly of filters from each major filter brand. Then, as oil returns to the sump, I have a pump which returns it to a second, 55 gallon drum, mounted on a roof rack, which contains only waste oil. When I get through about 3/4 the barrel of fresh oil, a light comes on, warning me I need to top off, and I head home to pump in more oil from my pre-mixed underground storage tank. At that time, I also offload the waste oil for recycling in various ways.
Sure, it's a little time consuming, but it's worth it not have to worry about what kind of oil I'm using any more... |

Farna's advice from a petroleum engineer is very good. My oil: Quaker State Defy high mileage 10W30. It's a high ZDDP, low detergent synthetic blend that is not expensive. It isn't super high ZDDP (1000 PPM Zn, 800 PPM P), but it is more than standard API SN and plenty to protect all but the most radical camshafts and springs. It has fewer detergents than standard API SN to help that ZDDP do its job and to not over-clean older engines that have sludge and varnish buildup holding the gaskets together to prevent leaks. Still plenty of detergent to keep the engine clean given proper oil changes.

No oil is worth anything if you don't change it. Seen engines get messed up simply because the oil w asnt changed
