Premium gas
National average for premium gas: $3.42 per gallon as of Sept. 28, 2018
Unless your car requires you to opt for premium at the pump, you’re better off filling up with regular gas. Using regular gas is safe for most engines and can save you 20 cents to 40 cents per gallon at the pump, according to Edmunds.
As of Sept. 28, the national average cost per gallon of premium gasoline was $3.42, while the national average for regular was $2.88. Gas prices are rising, so you could save even more at the pump in the future.
