whats the gas tank size for an 81? just tryin to calculate mileage

mileage is calculated by total miles driven divided by how much you put in at the gas pump. not by how big your gas tank is, that is completely irrelevant actually. using the gas tank size is not even close to accurate.

 

by "81" you mean 1981 or EA81?

Depends on which body style it is.

sorry i got an 81 ea81 hatch...and i was calculating the mileage going by fully topped off tank to when my gas light kicked on, with my odometer reading to get my average. its accurate enough, if anything my calculation would be just under the actual average.

 

and nevermind I found the fuel tank capacity... 13.2 gallons and I guess I averaged 31.3mpg freeway

31 freeway, nice!

yeah not bad, took a trip that was 413.2mi round trip. right when i was near my house the gas light came on. could of got better mileage but was going to coastal mountain roads so there was a couple times i had to put it in 4th gear.

Maybe im an idiot, and probably not far from the truth, but if i put in 11 bucks in gas, and can drive 130 miles, im only getting 11 mpg? Wtf

Well, uh, no-- $11 will only buy you a little more than 4 gallons of gas-- if you went 130 miles you were getting 30+ mpg.....

YES! im awesome! But not at math

and nevermind I found the fuel tank capacity... 13.2 gallons and I guess I averaged 31.3mpg freeway

 

Only if it's 2WD. A 4WD hatch tank is 11.9 gallons.
