Hey i was wonderign how much MPG yall are getting, I was wondering how much the average is so i can have a guidline. thanks!

 

I get about 16-17 MPG

 

Is it good if i'm only getting about 10 to 12 mpg with a occasianl speed burst? my cars milage is fishy...

 

Without knowing anything about your car it is impossible to say. That may be really good and it may be really bad.

My 99 gets about 16 - 18 around town and about 26 - 28 on highway.
My 67 gets about 5 around town and about 7 on the highway.

 

Well the only mods that are done to it are the K&N Air Filter, Denso Spark Plugs tower strut bar, gutted out air lid (stock air lid with the inside baffles cut off) thats all that i know of right now , i have only owned my car for a week and a few days, so i'm learnign all of the cars tricks it sucks when you dont know your own baby, but im gettin there, i'll be replacing the oil with some royal purple and getting a new oil filter , my mods are slow cuss of all my money is goin into the payments for the car, oh it also has a flowmaster muffler (ONLY muffler) with the rest of the exaust being the standard small size, oh yeah its a A4 2000 Z28

I average 19 in the city and 26 on the freeway (thats including when I get the itch to floor it). My mods are in my sig.

 

great thanks for the forum forward, I still cant seem to figure out why its getting such low milage, could a computer reprogram help out or what need advice, all my money is goin to either the payment or the gas, none for the goodies

 

i get 17-20 in town usually, and 24-27 on highway, depending on how long i ride 90+
but this was before the 3.73s

 

18 in the city, and 26 with the A/C on, on the highway.

 

23mpg, half highway half city, but always 10 to 20 over the speed limit.

Stock 2000 A4 Z28

Once you finish exploring the power and performance your new LS1 provides you will probably get better mileage.

I got 17-18 (and worse) mpg's, but now I've average out in the 20.1-20.9 mpg's most of the time. I've gotten as much as 26.

 

I hope so cuss all this gass guzzlig makes the Burban look good right now,......thats saying alot, when your burban gets better gas mileage.
