I know it's silly but I need to know :loser:
I read somewhere that if you use a higher grade gas than the manual says, then it could damage the engine over time because it doesn't burn or combust or something completely and leaves carbon deposites in the engine.
see i read somewhere that on 4 cylinders (which is what we drive) that you should use premium about every 4th to 6th fillup, it said something like "blah blah blah cleans the engine out blah blah" not sure if thats true, but im sure it would not hurt. am i correct.
