I did nto stop buying premium gas, but then I love this particular car and I do not want to do anyhting to create problems with it. Premium is more, but if you add the totlat cost per year, it is not that much. However I ahve always wondered if it is a waste of moeny due to waht my friend told me. Anyone know?
alot of gas stations screw people on octane ratings. I've heard of some scams where the high octane tank is just regular and the next grade up mixed.
