No ranting, just reading unbiased articles.
You are absolutely correct in picking a high psi rated oil over ZDDP content alone. Absolutely correct about aftermarket addatives. Have a read and your thoughts of SN afterwards for your 360 or in this I6 section a high lift cam on a 258: http://www.widman.biz/uploads/Corvair_oil.pdf This may or may not change your mind but it's an interesting read, at least for people like me.

fyi, i use the kind of 10W-30 that's Valvoline VR1, 20W-50. recommended by the engine builder, who set very particular clearances. i neglected to get the exact number, but he'd earlier said he uses .001" per 1" of journal diam (nothing unusual). iVR1 has got ZDDP. i've never had a problem with engines using the best quality chemicals i can find. i'm a cheapskate but this isn't a place i save money.

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

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.

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... |
