Stupid Newbie MPG question
I'm getting 14 MPG in mostly highway commuting. I have a 1983 GS with a RB header-back exhaust, accel plug wires, and a K&N drop-in. The car has 113K miles on it, idles correctly, and runs reliably. Is this gas mileage normal?
|
In town, highway, no.
|
Yeah you should be anywhere from 20-25mpg on the highway. Make sure your carb is working properly. Mine wasn't really so I had one rebuilt and it instantly gave me a hell of a difference
|
Check for vacuum leaks and be sure everything is adjusted right, you should be getting better than 20 mpg on the highway. Nice looking car!

i wish i got that good of MPG.. i burned a 1/4 tank sitting in the drive way for 20 min lol damn holleys woot..
if you have an extra $300 laying around get a wide band the take all the guess work out of it.. and pullin plugs sucks was the best 300 i spent cheers PaTricK |
Yeah, that is not good at all, Jack. Pete gets 25mpg on average, and hell we did an 840 mile road trip this weekend in his RX-7.
|
....with 4.78 gears!
|
I was getting 25 miles per gallon with mostly city driving back before I went Holley Carb. That isn't good at all. Get a carb rebuild kit or new carb. At the bare minimum check for vacuum leaks and those sorts of things. You should be getting better than that.
|
One thing to check, that is often overlooked, is the front brake calipers. If they are not fully releasing, you will get crappy fuel mileage, and shorter pad life.
If the car shown in your sig is the car in question, you are either very hard on the brakes, or the fronts are dragging. The front wheels having that much brake dust is usually a dead give away.................... |
16 mpg is a normal low for hard, hard city driving...the carb is not tuned correctly, though it seems to be....:cool:
|
Let's see, my in town mileage, cold weather, long warmups and hard driving, I have gotten less than 9 mpg. Suppose the bridgeport and Mikunki have anything to do with it? hmmmm.
Driving like a sane, normal, person, I usually get 14 in town and 24 on the highway. |
Good numbers Troch, I've got to give the in town part a try.

23/32 anyone?
|
I regularly get 27ish, with a good mix of highway, city.

And Mentor Alex, I got a ticket for my headlight being out. I'm gonna send Parma Alex after you with a tub of vaseline if you don't give me a time to come get my bezels. |
do you need the headlight too?
umm can you do it today? |
when my dad had his running he did something to it and was getting 25/30 but it went back to 19/21 when he brought it in for a tune up. one of the techs messed with the carb and he lost his great mpg
|
Yep it's all about tune up and fixing all the vacuum leaks and everything else. I got a good one now on my Nikki (thanks neighbor Bobby) and I've hit 391 miles on a tank twice in the last month or two (I drive it about 550 miles a week, so good data here). Anybody every get 400 miles out of a tank?

I've been getting 360 miles out of a tank on My Se with City and highway combined.
To the thread starter, make sure your secondaries are hooked up. If it seems you have low power and are getting crappy mileage the secondary spring that activates the secondaries is infamous for popping off. |
