Is using starting fluid bad for an engine?
Is using starting fluid bad for an engine? Ether is a solvent, and when mixed with oil it will dissolve and breakdown the oil. If enough starting fluid is used on a two-stroke engine, it can keep the included oil mixture from doing its job of lubricating the engine. That can score bearings and pistons and eventually lead to engine failure. Can a car cold start without starting fluid? Cold: just cranks, no start. Cold could be anywhere from 80f-50f ambient so far. So to start it cold I take the air filter off, shoot on shot of starting fluid...
