slant 6 oil weight

I run almost 100% synthetics in gas and racing engines but use dino oils in my 2 diesel trucks and just change it a lot. The protection that synthetics offer if something happens in the engine to drop pressure is very real. But it is not for everyone if you are on a budget (though the cost difference has gone down) or are working on the engine.

If you are running synthetics and changing your oil as often as you would with dino oil you are wasting your money. Even in the fords with the HPOP you can go longer on an oil change with full syn and let's face it. They hold 4 gallons of oil. That's really where the money makes sense. Full syn, pay more up front, less changes. DIno oil is cheap but breaks down faster. My dart gets a change once per year no matter what.
