Yes its best diea, Don't Drive LOL
Change Driving style
oil change on time

yeesh 300km? i get almost 450 a tank and i thought my mileage was bad, and thats also with me running the crap out of it in town, i.e: leaving lights hard and revin over 2500. but i do drive mainly highway but its around 90-100km/h. but you can lose upto 15% of your mileage from incorrect tire pressure so i make sure i check it every 3-4 weeks

I am pulling 25-28MPG commuting with my 94 (all highway). However, playing on weekends will drop it below 20 quite easily. As of the moment, everything is stock.

That 450 a tank is high 20's for gas mileage

What psi are your tires. 30 psi.

Is 35 psi to much.

Depends on the tire. I have 35 in mine. The edges were wearing due to the previous guy running them underinflated.

well you can raise it right upto 44psi and gain a mpg or 2 but at the cost of traction and handling, and ive seen a few guys do this. but i keep 35psi in mine and check it every 3 weeks cuz incorrect tire pressure can subrat upto 15% of your mileage

change your plugs.... my car got 1L/100km better when i went with Bosch Platinum 4s

WHAAAA!!!!! Thats insane... im completely stock except for exhaust and Im getting MAYBE IF I DRIVE LIKE A GRANNY 160MILES to a tank... which is what closer to 260KM/tank... even that little but more would be nice =[

geesh
I envy you hardxcore... lol

1 tank lasts a summer for me but then it sits in the garage but for Wednesday night and the odd Sunday show. :wink:
