What kind of gas does the 2012 Nissan Maxima take?

The 3.5-liter engine in the 2012 Nissan Maxima takes 91-octane premium gasoline. This information can be found on the inside of the fuel filler door and the owner's manual, if needed. Octane levels measure the resistance the fuel has against engine pinging. This is the sound that's created by the engine during acceleration. A higher octane rating translates to less noise during combustion. 91-octane means there is 91 percent octane with 9 percent heptide. This is a popular pick for high performance engines. The 2012 Maxima features a 20-gallon fuel tank. It returns an average of 19 mpg in the city and 26 mpg on the highway. Keep in mind that oil plays a role in fuel economy, as well. So, routine oil changes not only prevent engine damage, they enhance fuel economy and performance, too.
