i check my mpg every time i fill up, and usually i get about 180 miles on 12.4-.8 gallons. this is all city. that ends up around 14mpg. is this normal? but when i drove to austin from dallas this weekend on a full highway tank varying from 75-85 the whole time and a few trips to a 100 , i got 32mpg with the a/c on the whole time and my girlfriend in the car. what could cause my city mpg to be so low. would changing the fuel filter get me better mpg? i recently had the oil changed and the tech said it looked like the original filter was on. car has 53k on it with a m6.

 

this exact thing happens to me, 180 a tank in city, and when i went to austin from houston i used a little over a 1/4 a tank, thats about maybe 300 or more like 200 somthing miles.(give or take) i dont know what it is, i think its my way of driving.

 

I haven't driven my car pure high way in a long time, need to go and see what kind of gas mileage I can get, but the car doesn't have a/c so that kinda warants taking another car. I can get about 225 off a tank if I really let it get low.

 

I checked mine last week, I was at 17mpg. That is mixed city and highway (65% city, 35% highway). That included a heavy foot, and about 10 miles doing 90 mph and flooring it constantly (playing with some cars on the freeway)

 

im from the garland/mesquite area. only mods on the car are a hooker catback. im seriously thinking about changing the fuel filter i just dont have time right now. how much should it cost to get like an oil change place to do it?

 

My car is completely stock and i do a mixture of city and highway driving and i usually get about 19-20mpg. And i have a heavy foot alot of days.

 

I just got 200 miles to a tank. I had a big heavy foot day today though, i have noticed...the LT-1 has great fuel economy on the highway while just cruising

 

You have that 6 spd and the 6th gear is at a .5 ratio. That is why you get awsome highway mileage. I get about 12-14 around town, and about 25-27 on the highway with my 6spd

 

Change the fuel filter yourself.. i just got some cut off pliars and snap it in... esaiest filter i have ever changed. Than again i've only changed 3 but hey lol. I get about 180 to a tank around town, and just drove from were i live to St. Charles(about 80 miles) and back and i got about 280 miles out of here.. i guess thats regular for the lt1
