I never have a chance to really check it by filling up all the way and let it run down low and fill it back up do to low $$$ recently, BUT when I fill it about 3/4 and drive till 1/4 or the orange lines I get about 22mpg :( I know thats pretty bad. I wonder why though.

I recently changed plugs and wires, oil and filter, gutted full airbox. I don't have any coolant or oil leaks. I'm still needing to change my fuel filter though.

Hah, my last two tanks were 30.2 mpg and 25.9 mpg. Why thank you LN3. Got to admit tho, those L36s get some INSANE mileage, I was RACKING the pedal in my 98 and NEVER got below 18 mpg, i was like WTF?! If they weren't slightly ANNOYING as far as reliability goes, I would have tried harder to get another one. But I like my LN3. :P

yeah with a trunk full of crap, Im usually getting around 31-33 going around 73-75. I dont think the fuel filter has ever been changed, thats the next thing on my list and Hopefully I'll be able to gain another 1 mpg.
