Are you buying more expensive fuel than you need? Many people are.
Your owners manual will tell you the correct gasoline octane for your vehicle. Most cars run fine on unleaded regular gas. Some high performance cars require premium octane gasoline, but if your car is running without engine knocks on regular, then buying the more expensive grades of gas is a waste of money.
Some people claim that their cars get better gas mileage on mid-grade or premium gas. That may or may not be the case, but even if your car does get better mileage on a higher grade of gas, you need to compare the higher cost of the gasoline against any improvement in mileage and figure out whether it’s really worth it. Sometimes people expect to get better mileage with premium gas and they unconsciously drive with a lighter foot on the accelerator and at a lower speed, so they get better mileage but they would have gotten the same mileage with regular gas.
Check your owner’s manual and save money by putting the right grade of gasoline in your car.
