ok does anyone have or has had one of these?
and how accurate r they?

Auto Meter ecometer 9100 - Gauges

 

Well i have not used one and i just use my odometer to help figure out my daily average being iam a $10 at a time kinda guy lol.

But the way it taps into the ECU and takes info off all the parameters i can see how it spits out it's numbers. I would think it would be pretty close to what your getting but not dead on accurate i would think it would be +/- 3mpg.

 

oh ok
i always forget to check my odometer when i fill up and record it so thats why im askin. lol
so would this just be a waste of money

 

won't work on your car anyways, too old....

 

oh thats sucks
oh well, saves me money now lol

thanks
