Fuel Saving Tips
With forced induction cars it's best to turn the engine on before your cabin checks & putting your seatbelt on & it should be the last thing you do before getting out of the car. While you'll use a little more fuel short term it will make sure the turbo/supercharger remains in good condition & keeps the engine healthy, a healthy engine runs better, uses less fuel & requires less maintenance. This is the reversed for non-forced induction cars where you want to turn the engine on/off just before you pull away/after you stop.
