Good gas mileage refers to the distance a vehicle can travel per unit of fuel consumed. It is measured in miles per gallon (mpg) and varies depending on several factors such as the type of vehicle, fuel octane, and type of fuel used. According to Autolist, 23 mpg or higher in combined EPA fuel economy is considered good gas mileage for a vehicle. However, some hybrid models can get up to 58 or 59 mpg, while some non-hybrid models can get well into the high 30s or even low 40s in terms of mpgs.

It is important to note that factors such as driving conditions, weather, and driving habits can affect a vehicles fuel efficiency and the number of miles per gallon it can get on any given day. The EPA estimates the gas mileage of new vehicles and can give an accurate figure that will help you decide which vehicle to choose.

Here are some examples of good gas mileage for different types of vehicles according to Car and Driver:

• Standard SUV: Lexus RX 450h AWD Hybrid gets 30 mpg
• Minivan: Chrysler Pacifica, Honda Odyssey, and Toyota Sienna 2WD get 22 mpg

It is also possible to calculate your vehicles gas mileage by running the vehicle for about 100 miles with a full tank and then topping off the tank with gas.
