hello everyone

can anyone please post their milage that they're getting off their non-type S models?

my tank is been really strange since i've bought my car in nov. 2004. i get about 350 km / 217.5 miles off my first half of my tank. then i can only get about 110 km / 68 miles off my 2nd half.

off a full tank on average i can get 470 km / 286 miles and the most i've ever been able to get is 512 km / 318 miles... is this normal?
