I have a '48 F-1. As I read through the Ford service literature of that era ('48-'53) I find that detergent oil was just coming into service. Not mentioned in early literature but recommended a year or two later. It's not a matter of whether it was recommended in the 30's and 40's - it didn't exist!! 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.
