Mopar noob
So I just pulled out my 340 to put it in my dart and when I drained the oil it looks dark green. The engine was rebuilt not that long ago, but not by me, so I don't know if it's some type of break in oil or what. It also has a gas smell to it. But I've never changed oil that doesn't smell at least a little like gas. It also could have some gas from it sitting in the cylinders while the car sat. It hasn't really run for more than 10-15 min since a year ago. Should I worry about the rings, is it gas? I don't think it's coolant, so my only other thought is gas or something.
