Hi. I don't use my stovebolt in a truck. Someday I'd like to have one, but in use my 1950 flint built 235 in a 1950 chevy deluxe. The motor was rebuilt buy the owner before the guy I bought it from in 1991. I don't know to what extent. It's had straight 30 weight non-detergent in it, but many have told me to use 10-30 detergent. What do you all think? I bought the car and have only owned it in below freezing temps, so there is some smoking. She purs like a kitten once she warms up, and relatively clear exhaust. I have an oil filter btw. Fram c4p.
