I was working at my brother-in-law's house the other day. I dripped some oil on his driveway and was rooting around for something to clean it up. I found an old can of starting fluid and gave it a shot. It completely dissolved the oil in seconds and then evaporated leaving no trace of stain. I know now why you should avoid using it to start your engine but the question is, can I use it to clean the engine? Has anyone tried this? Can anyone think of a good reason not to try it?
