I’ve been hearing a lot about both Marvel Mystery Oil and Seafoam for cleaning out engines, and I’m curious which one works better for a Jeep Grand Cherokee. Anyone have experience with either? I’m looking to do a deep clean and get rid of some of the gunk that’s built up over time. Don’t want to end up using something that does more harm than good!
