No, but it's bad on your pocket book. Use whatever is called for in your vehicle. Using a higher grade than what is called for won't hurt anything, but it won't help anything either.

No, just make sure you are putting in good gas regular is fine(unless you have a high performence engine). Once in awhile high grade because of the detergents in the fuel to help keep the engine running clean and smooth.

No, gas is gas as long as you use the proper grade for your car.
This is why gas stations advertise how clean the restrooms are, because the gas is basically all the same. In fact most get their gas from the same distribution center.

HI,They say you should switch grades from time to time. Your car will run better on a higher octane,you will feel the pep in the pick up.You should also take car on a expressway and blow that carbon out of those cylinders.I think purchasing a different brand once may help out with performance of the car.So yes it`s good to change grades .Good Luck

If you notice your engine is sluggish or pinging, you can try mid-grade gas and that may help it. My dads 2003 subaru outback calls for regular in the manual, but it pings unless he uses super.
