MPG's?

[UltrasportFreak]

So I bought an '05 Ultrasport Avant 1.8T about a month ago, so I'm still getting used to everything and trying to figure out all the different parts and pieces of the car. My vehicle has an APR chip in it, not too sure which one, but I know that it requires Premium fuel now.

On the highway / freeway going a steady 65 mph on average I can get 28-31 mpg on a tank. My last tank driving probably 80% city, I got almost 21 MPG.

After my most recent fill up (2 1/2 days ago) and driving 50 miles, 70-75% city, my fuel gauge already reads 3/4 tank. I never remember it reading that low after so little miles. Is this normal for an Avant? Or could something be wrong? Anyone having any input? Thank you in advance!

PS - car is still under warranty, so any recommendations towards that if necessary are appreciated.

on my b5, 50 miles on the first tick on city driving sounds about right. I usually get 40-50 miles on the first tick in city, and about 65 miles if I'm doing all freeway.

Be happy, I never get more than 120 miles per tank with city driving in my S4 Avant.

That's around 8mpg.

Holy Crap! My old 91 Landcruiser beat that by 3mpg. Of course it went 0-60 in 15 seconds.

Did you have a hole in the tank?

You may have a bad fuel level sender. Go see how much it takes to fill the tank.

When my sender was bad the gauge would be fine until it got to half a tank and then the needle would drop to empty. Others have had different experiences.

Naw, it just weighed about 5000# without any body or anything in it. And it was a I-6 with about 155HP. It was a bulletproof, reliable engine and would go anywhere...just at its own pace. Luckily it was a 25 gallon tank so I only had to fill up every 200 miles!

Not sure who that was directed to, but I normally fill up at or around 1/4 tank and it will take anywhere from 11-13ish gallons so I'm sure my sender is quite fine. I normally track my mileage on over tank too by reseting the trip odometer - although I'm not quite sure why I track the mileage.... I guess for my own knowledge.

I'm pretty sure my fuel level sender is working properly, cause I'm still getting 20-22 MPG's for city driving, and thats calculating the trip odometer to the amount of gallons it took to fill up, so I think I'm good if 20-22 MPG's is pretty standard for a chipped 1.8T Avant.

i have a GIAC FXKO3 chipped USP avant and i get about 43mpg highway. i never really keep track of the city mileage.

Jesus thats horrid!

I hope my A6 gets that when its done!

Whoa, how the hell do you manage that mileage!? I'm still pretty new to all of this, so I'm not familiar with what GIAC FXKO3 is, maybe that's the huge difference between your Avant and mine. The most I get on the highway is about 32, with an average of 28-30, but through research I find that normal.

Although I keep track of my MPG I really don't care about it because I don't drive that many miles each week - but do drive my car every day to and from work + running around. I normally fill up once a week and with the price drop on gas it normally runs around $20 to fill up.

[Silver Bullitt]

Yeah so would Chipping make that big of a difference in MPG?
If so I need to Chip my S4.

Cruise Control FTMFW!

Find a lane and stick to it. The less you touch the gas pedal, the more mileage you get. My car is chipped, front mount, 380cc injectors, catless exhaust. It's all in how you drive. I try and keep the RPM's always around 2500 to 3000 RPMs and ride the cruise.

[ottyavant]

My avant has an unmolested motor I average about 410-420 per tank...... the best i've ever experience was when I drove from Hayward, CA to Santa Monica, CA.

I got about 545 before I had to fill up again, I took my roof rack off and I was running 17in" stocks. I was drafting a suburban that was averaging about 80-85 the whole way, I also coasted the entire descent after the grapevine and onto the 405.

I could not believe how efficient my car was and I was using the cruise control a good part of the drive

[D's Avant]

20-22 in the city and 29-30 on the highway (75-80 mph) for my 1.8 B5 Avant.

That's exactly what I'm getting, so now I'm comfortable knowing that it's not just my car. But I'm definitely going to work on the cruise control / using my TIP at 2500-3000 RPM.

[Silver Bullitt]

Yeah I am at about 17 for city, probably 25-27 highway in my B5 S4 Avant.

[lookaught]

20-22 in the city and 29-30 on the highway (75-80 mph) for my 1.8 B5 Avant.

That's almost exactly what I get too. 21.5mpg (calculated by hand after each time I fill the car up with gas) driving about 60% city. I mean CITY driving though...through downtown, lots of tall buildings, short blocks. It's also pretty hilly in Pittsburgh. High 20's on the highway, which is also pretty hilly. On flat highway I get over 30mpg.

[InTTruder]

Did 350 miles yesterday w/ cruise set to 80. Got a flat 24mpg, wjhich included about 10m og stop-n-go right after the fill.

[Greyhound Guy]

For Sep, Oct, Nov that I have recorded, my best TD was 443 miles. My highest average is 29.8. Top of the tank is small as is the bottom. The bulk starts right after 3/4.

[steve_malton]

On a full tank I get about 630 miles (1.9TDI diesel remapped to 180BHP)
