Yes, and the best answer is ... do you feel lucky, if that is the only problem you could cause? You know the question that guy that was recently seen talking to an empty chair asked a criminal.

Lmao the cheap gas causes detonation or very advanced ignition. Causing a knock causing a lot of stress on the entire engine. So Joseph is correct, do you feel lucky.
