This handy infographic shows you the recommended fuel type for car models built in 2012 or newer. We hope this clears up any confusion you might have about what type of gas to put in your car. If your car isn’t listed here, refer to your owner’s manual or the inside of your gas cap for the recommended octane.
Which fuel grade is most popular today?
Out of the 300(ish) cars we studied from the model years 2012 and up, 53.79% take regular gasoline, while 44.09% require the top end premium. Only a few cars required midgrade fuel and those were cars equipped with the Chrysler 5.7L V8 like the Dodge Durango, Dodge Challenger and Jeep Grand Cherokee.
As expected, many luxury brands require premium gasoline across their entire model line. This includes BMW, Mercedes-Benz, Audi, Infiniti, Jaguar and the ultra-luxury brands like Bentley, Aston Martin, Porsche and Ferrari. However, we were surprised to see a mix in the model lines of Cadillac, Lincoln, Land Rover and Lexus.
Land Rover actually recommends regular fuel for the LR2 which probably is good when you’re roving land in a country that doesn’t have higher fuel grades. The vast majority of turbo or supercharged motors have to run premium gasoline as they are more susceptible to engine knock.
