Wow.I think some of you guys are over excaggerating (I cant spell)
I do an average of 130miles per week.
I used up about 5 gallons of gas per week
So a lil math and Im doing an average of 26 miles per gallon
26mpg?
That sucks for you.
My EH9 never failed to get 32 mpg.
That's an EH9. D16Z6, 4 doors, A/C, P/S, moonroof, subs, full interior, ABS, 15" Konigs...etc...
Why wouldn't an HX, CX, DX...etc... get better mileage? Less weight, smaller engine, less parasitic engine load...etc...
Hell, my Mazda got 23 mpg on the last fill-up. ($3.89 a gallon ) I got 30mpg strictly freeway and I have 2X your displacement. Might be driver error in your case.
