Hi guys, Newbie to the G37 world.

I was wondering how much of an influence does Winter driving have on your gas mileage vs. summer driving. I noticed from September time i was getting about 630km on my 2012 G37x Sport Sedan but the following weeks as the weather has been getting much colder, hence using the heat, seat warmer etc. I am getting around 500km. I think this is a huge difference?! Any help or tips you guys can provide would be great.

Thanks

 

I used to get around 21.5mpg but about 2-3 weeks ago it started being around 19.5mpg but I think it's 'cause I added the Stillen Gen 3 Intake and Fast Intentions Exhaust

 

Winter gas, the gas is blended different for the winter. You get less mpg.
