Hi Everybody I have a Honda Accord Euro 2003 which i bought Brand New. As time has gone on i Have put some modifications on and noticed that my KM per tank is declining with every mod. I was wondering what everyones KM per tank is. I have done a little outline. Looking forward to hear what everyone else is gaining.

Fuel Caltex Premium 95 - $94.00

2003 Car Bought Brand new - No Mods around 600Km per tank up to yellow petrol light

2005 Back Quater exhaust upgrade, same original size pipes from cat, two twin 2.5 inch tips on each side - 500km per tank up to yellow petrol light

2008 CAI Custom by Hypertune - 450Km per tank up to yellow petrol light

2008 Top Speed Headers, Changed original Flex pipe to Double braided flex pipe - 430km per Tank up to yellow petrol light

I dont feel that i am pushing the car more than what i did when i first bought the car.

Hope to hear everyone elses thoughts.
