I filled up my tank on Thursday. My car told me to expect 325 miles. At the gas station, I reset the trip odometer so i could check how accurate the car's estimation was.

Now, it's Sunday night. I just hit 270 on my odometer, and the gas warning has popped up.

I am hovering around 16.5 mpg now, which i think is pretty crappy gas mileage.

2 questions...

1) Why is the mileage reading so erratic?

and

2) Why am i only getting 16.5 mpg.

i have an '02 tiptronic 1.8t.

Thanks.

 

alright, well i figured out the erratic gas mileage reading...

if anyone else was wondering about this, it has to do with the air conditioning. i turned off my ac, and the mileage went right back up to the originally expected 325.

so now, i guess my questions are, is 16.5 mpg decent on an '02 tip 1.8t, and is 325 miles per tank alright?

 

If your gettin 325 then your mpg is higher than that. Isn't the tank 15 or 16 gallons?

 

15.6 gallons

 

So your gettin more than 20mpg.

 

hmm, interesting.

i didn't know the tank on the '02 a4's was 15.6 gallons.

since i bought the car used, i guess the person before me just got really bad mileage due to mostly city driving...cause my avg. mpg reading is only 16.5 mpg. it's slowly been creeping up since i bought the car, so i guess once i put some more driving on it, it'll be around 20 mpg. that will be nice to see.

thanks.

 

I have a 2001 A4 1.8TQ that average 9.8L / 100km.
