what is it people i want to get this automatic and i wanna know how many gallons it holds and how many MPG can i get out of a tank??

You know a simple search on google can find you lots of answers ...



14.5 gal (1979 & '80) 16.4 gal (1981 & later)



Around 17 mpg (City)

Around 22 mpg (Hwy)

yea i did that but thats stupid then cuz the 13BTT does the same thing so what would you preffer the 12A @100hp and 17/25mpg or 13BTT @ 250 hp 17/25mpg, i need an ans. from someone who has a 1st gen

i'm pretty sure my 84 has a 16.9 gal tank...but I guess I could be wrong on the exact size...and I get 19mpg with the 5-speed no matter if I drive like a granny or a formula one racer...so I go with the second one



hmmm...recently i been fillin up around 200 miles on the trip odometor...which is a little over 10 gallons...but my gas guage doesn't work and i havn't really been in a hurry to fix it



and generally speaking chop off a few mpg for the automatic



i'm one of the few people on here that actually trys to improve my MPG...most people don't really care...after all...its an RX-7



and another thing...a first gen will run great on 87 octane...its actually best...if you try to pour 87 into a 13BTT it'll run like crap...probably sputter and die...gotta run those things on high grade...so you're not going to really save much on gas



If you want good mileage learn to drive a stick and buy a diesel VW https://www.nopistons.com/forums/pub...R#>/tongue.png

60+ mpg sounds damn good to me for my daily driver ... maybe I should start looking LOL.

couldn't really tell you...i've done all sorts of things to my car...used to get 13-14 when I bought it...but i changed out the plugs, wires, coils, carb, stripped emissions, stripped the cats and replaced with a straight pipe...glass pack on the back



uhmmm



I drive the crap out of my car...people always think its going to blow up...cuz they never hear anything rev that high usually https://www.nopistons.com/forums/pub...R#>/tongue.png



but I still get a solid 19 no matter how i'm driving...even at 80-85 mph on the interstate

much more than that tho...and it drops fast https://www.nopistons.com/forums/pub...R#>/tongue.png

I get 27+ out of a 12a 6port, 5 speed, no nest, single belt, 18 inch pipe and gen muff. best Ive ever seen out of a first gen.
