i just wanted to know.

and the reason for the premium gas only is because it has a much higher resistance to pre-detonation due to compression, or "ping" as some people call it. detonation can cause the combustion chamber to heat up wrong and basically turns your car into a 4 stroke diesel. since it ignites closer to TDC, it must be able to compress more to fire properly. i run mid grade in my car anyways, since its a VERY high mileage motor, and carbon buildup in the combustion chamber can actually increase compression and cause hotspots, making the car more likely to ping.
