How many miles to the tank are you guys getting? In city and highway?

My cousin had a '94 6spd Formula and swore up and down he made it from where to lives to San Diego (390+miles away) and still had some gas left in the tank and cruising at 95-110mph the entire way.

Yet, the guy who sold us our house has a '95 6spd Z28 said he gets 22mpg cruising at 90mph. So that's 360 miles per tank or so.

So what do you guys get in city and highway? What about you automatic guys?

 

Back when my car was stock, I would see up to 26 mpg

 

I'm seeing about 220-280 to the tank depending on how spirited I drive my car, but my car runs really rich.

 

I got around 170 this last tank

 

The Z can get about 300 out of a tank with all Interstate driving. The norm is 260-280

 

Post up your transmissions.

 

Will a clogged cat hurt gas mileage?

 

Big time and rob power aswell, its a restriction.

 

180-240 miles per 12 gallons or so

 

Yeah I get anywhere from 170 to 250 in 12 gallons. The colder it is, the worse my mileage is cause I warm the car up often when it's cold. My car has a miss though, so I'm sure I could do better. I'll fix it when the temps go over 30 someday.

 

22mpg hwy, less in city,

I average about 180miles in the city on a 15 gallon tank of gas.

Low 300's driving interstate
usually get around 17-18mpg-city

Having 3.23's and a m6 really helps sometimes.

 

Well when I was stock 323's. auto. I was getting 300 per tank or about 20mpg's. now with mods/373's and with new 3800 stall. I get about 200 per tank at best so about 13 mpg's.

 

19-20 50/50 hwy-city. Got 27 on a 300 mile trip one time...

 

im lucky to get 200 miles on a full tank in the city. hwy is much better though. I dont know why my city mileage is so much worse because I put it in 6th and cruise at low RPMs.
