Only emission controlled cars do not like zinc (O2 sensors) The rest of the motor loves it

So as a tool engineer do you follow any SAE specs? If you would bother to read your owners manual there are SAE specs on fluids for your car. One of which is oil. I see no reason or benefit from not using the recommend oil called out by the people who designed and built your engine.

Chevy WILL recommend the best oil available at the time. If a little more zinc was good it would not make any difference as it was not available. In my 1972 Honda CB750 I add a little bottle of zinc additive at each oil change. Dan

I am pretty sure the amount of zinc in oil has drastically changed (lowered) since the engineers specd the oil to be used a quarter century ago. Dan

no I highly doubt that. The valve train is what spec is for. The valve train used in LT-1 are still in use today on just about every production car.

While you can still expect some zinc in your motor oil, today’s oil doesn’t have as much as it did in the past. The American Petroleum Institute’s rating caused the industry to systematically reduce levels of zinc in their oil since 1994. If you have a newer car, this should not be a problem.

do you realize how many different spec oils there are. Oil rated in the C category has the amount of zinc needed for engines built before 1986. So your general assumption is wrong This is why the SAE papers and understanding comes into play

I love oil threads - here's my opinion that I am sure will ruffle feathers.
Grab a jug of rotella T6 diesel oil (5w40) and don't look back. It's full of good vitamins and minerals that the motor likes. As long as the engine is not an oil burner - the o2 sensors, cats, etc will never know the difference.
It's in my 350-650k mile powerstrokes, wifes 3.5 ecoboost, every vette I've owned, riding mowers, small engines, almost every motorcycle I've had, etc - AND the oil is nearly $20usd/gal if you look for specials/coupons.
