RE: Is it alright to run synthetic oil in my 79 mustang 4 banger?
Some guy at an auto parts store told me to pick a brand and stick with it but I dont think it would even hurt your car. I just cant see it messing up your engine like the guy says. Well I dont really care, oil is oil.

Not really, some oils have been tested to stand up against stih while others have not been tested, stay away from those because they might cause some damage
