My fuel economy is crap! - I get 6.5km/l going to and from work, and about 8.5km/l on motorways (I think the conversion to mpg is x2.3) Still, its worth it!
Filling tank costs approx £58 and I get approx 250 miles - so I have my own pump at local petrol station lol. Has anyone changed the JDM 60ltr tank for a UK 75ltr?
