alright i have been trying to figure out my freakishly good gas milage. i have been getting about 28Mpg in town which frankly is pretty damn good.

but why am i getting good gas milage? my catalytic converter has been chopped out would that do it?

i am wondering because if its something i can control mabe i could make it better!

 

Yep... controlling your foot.

 

controlling your foot and have a good tuneup does the trick. you would be surprise how good most old cars get mpg

 

I average about 27mpg...and I like to use a heavy foot now and then.

 

i have drove my 280zxt 2+2 to albq new mexico and back 400 miles there and 400 miles back on " 1 " full tank of gas in my turbo... i get awsome MPG but my cat is gone and i put on a HKS straight Muffler...thats 75 mph there and 75 mph back... too... i love my 280zxt but laltly shes been dying when shes getting warmed up... sigh...

 

Im no math wiz, but that sounds like 800 miles on 1 full tank of gas in a 2+2 turbo. . . .so by that math my coupe turbo should be able to make it oh, well lets see

1 full tank of gas+the current price of tea in China divided by the circumfrence of the moon on the 3rd monday of june . .carry the 1

Yea . . .i could get about 1600 koalameters on 1 tank

 

Actually... the easiest way to get 50mpg (what nismo619 apparently gets in his fully loaded 280zxt) is to cut holes in the floor & run while driving. If you can run 75mph like nismo619 can, then you get very good gas mileage. But you really do have to add the price of tea in china for that to work, and only if it's June 3rd.

 

my name is not fred flinstone.
last time i filled up i was at 1/8th of a tank and i am now at 260 miles and 1/4 of a tank away from 1/8th. i had to do some hard driving this time, i acually went on the FREEWAY! my car has a low top speed i can tell. 80Mph is arround 4k on the tach in 5th. so i am not saving any gas there. but i was in a hurry, and then i ran into alot of stupid people i would rather have behind me, you know the type. so we'll see.

 

And the 2+2 actually has a gas tank that is a couple gallons smaller than the coupe!

 

Removing the CAT on an otherwise stock N/A car will NOT improve mileage.

It may (and is most likely going to...) slightly DECREASE Mileage.


800 Miles on *1* tank of gas in a 280ZX = giant heaping pile of B.S. (unless of course the car has been modified to fit a 40+ gallon tank).



Rod.

 

back when i had my 81 i was getting about 350m to a tank with mixed freeway and city.

 

These cars have almost always been advertised as 400+ mile cars per tank of gas. With a 20 gallon tank, that's not too hard to achieve as long as you're breaking the relatively easy 20mpg level. 800 though... NFW.

 

The most I got with my '81 280zx, back in the day. Was like 380 some miles to a tank..Of course I ran it pretty close to zero..lol But there is no friggin' way..You can get 800 miles to a tank of gas..I call B.S. on that one also.

 

No where near that in my '83 2+2 NA, especially in the city. On the Freeway at 75ish I was pulling 24 to 26mpg in the city I was lucky to get 22. I have a heavy foot too.

 

You guys forgot hes got a turbonator in his intake and a tonado and a adjustable ecu chip upgrade from ebay for $0.99! Of course hes getting 800 miles per tank

 

Which is about 750 miles further than the parole officer allows for travel...

alright i ran it down to 1/8th and i got 320 miles out of it in town

 

Man, 800 miles to a tank... .... .... ....maybe it's a hybrid ZX?

Turbonator, resonator shish boom bah!! Bugs Bunny Bugs Bunny RAH RAH RAH!!!
