Gas mileage.?

Would you get better gas mileage if you put a higher grade of gasoline in your car?Gas mileage.?
no
No, you sure wouldn't.



Your car won't go any faster if you put ZR-rated tires on it, either. And your computer won't go any faster if you put RAM DIMMs in it that are faster than spec.



All it'll do is waste your money.Gas mileage.?
Not if your car was made to run on regular gas. The only advantage of a higher grade of gas is that it reduces knocks (pinging). If you don't have a problem with knocking and you put higher grade gas in your car you're just wasting the money.



In fact modern cars with computer-controlled ignition and fuel injection won't knock whatever you do! The computer senses the knocking and changes ignition timing to prevent it. So if the car is made to run on premium gas, regular gas will work, but you won't get as much mileage because the later spark is less efficient.
No. Higher octane rating gasoline is only to reduce engine knocking. If your engine isn't designed for it, you'd just be wasting your money.Gas mileage.?
