Fuel Mileage

Varies significantly across cars, depending on mods, driving conditions (highway or town), the RPM shifts occur, condition of the car. Several factors can affect mileage particularly the ignition timing, fuel filter, the oxygen sensor. Also depends on whether you’re driving an SC or NA. Typical mileage:

  • 26 mpg average; 19 mpg under spirited driving, to around 32 mpg for calm highway driving.

Here’s some typical experiences from owners. Feel free to measure and add your own. Measure your mpg using the method below over a number of trips, preferably at the same gas station:

  1. When you buy gas, fill the tank all the way up, and reset the trip counter.
  2. Next time you buy gas fill the tank all the way up again.
  3. Now divide the distance traveled since last fill, by the number of gallons/liters of gas you just bought.

Tip: Because it’s hard to fill the tank up to the exact same volume of gas every time, you usually need to average your gas mileage over several consecutive tanks to get a trustworthy number.
