When it did come on the market Ford embraced it - for the same engines we are running now. Detergent oil doesn't clean the engine - it keeps the sludge from forming. I can't imagine not using it. I run it in my original '48 engine and am happy to do so. I've used it in Model A's, V-8s and old tractor engines. Embrace the new (Late '40s!!) technology!! Same discussion for multi-viscosity (10-40) oils.

Great! That will make things a lot easier for me.
Just one last question.
Why do antique auto parts dealers like Mac's still sell the non-detergent engine oil?
