Just thinking to myself. I want to try SAE30 in my 6.9L IH engine in my Ford pickup. Don't try to talk any sense into me....I just want to see how it does.
Problem is that the engine calls for a dual rated oil. I have only seen SAE 30 with a gas rating or a diesel rating but never both. Who makes a dual rated 30w? Or maybe a SAE40?
