Do you get worse gas mileage in the summer?
Hot weather can actually increase your fuel economy. Your engine warms up to an efficient temperature faster; summer grades of gasoline can have slightly more energy; and warm air causes less aerodynamic drag than cold air.
Why does my car get better gas mileage in the summer?
Warmer Air Warm temperatures cause the air to expand and become less dense, so when your car pulls air in, there is less oxygen present. Less oxygen means less fuel consumption. This isn’t the best for power, but it does help from a fuel economy standard.
What does it mean when your car has bad gas mileage?

How does motor oil affect your gas mileage?
The type of motor oil that you are using can also affect your gas mileage up to 12%. You want to use motor oils that are high in reducing friction. Either use a synthetic oil or the oil that the car’s manual recommends.
