I have had my 8 for about three weeks now. Its a 04 6spd with the appearance package. I knew the gas mileage wasn't great with 8's but I wanted to check and see were I was with other owners. It has been kept up with all maintenance and has 54k on the car, 35k on engine. I drive about 25 miles to work each way half city and half hwy. I filled up and got 235 miles just as the gas light cut on so i could have got a few more. Is this good? I use 93. I drive pretty conservative. Thanks for any insight.

 

Middle of the road, or good side. Sounds like you have a decent engine on it. Do an all-highway cruise stretch and you will probably see ~280-320 for a tank.

 

235 isn't bad, I get around 160 in-city enthusiastically driven miles per tank. I will replace coils, plugs, and wires soon and see if that helps a little.

 

Thanks for the quick replies, what size fuel tanks are in the 04 8's ?

 

anything near 200 miles on a tank is good for the 8.

 

tanks are 15 gallons for all series I's im pretty sure

 

15.9 gallon tank, all years.

 

hmmm thats interesting, driving my car like i stole it i average 250 miles in town. and when i fill up it takes like 12.9 which means i still have 3 gallons left????
ive been attempting to drive nicely for an entire tank and see how i do, but then i will be extremely late for something or it will rain and i wanna have some fun and whooop there goes that!!!

plus i live in chicago, so traffic always sucks

 

Yup.

Since the gas tank is split left to right and has to siphon back and forth when you are under 1/4th of a tank, you might have varying amounts left from one fillup to the next. Generally flat cruising keeps the sides balanced, and it's at 2.8 gallons left when the light comes on, 13.1 gallon fill.

 

so if i take a hard corner, all my gas will go to one side lol just kidding. well thanks for the info, love learning new things about my 8

 

that's not far from the truth navy. If you are low on fuel AND its mostly on the side where the pump is NOT AND you take high g turns to the left you can get fuel starvation.

 

so its a split tank however the pump only picks up fuel from one side?????
if so which side is it??

 

Pickup is on the left side. High G left turns under 1/4th of a tank CAN (repeat CAN) cause fuel starvation. The lower on gas you are, the longer the high G left is sustained, the more likely you are to hit the fuel starvation. Above 1/4th of a tank and the gas is "cresting" the split, so you don't have this issue. Below that and you are relying on a fairly slow siphon to transfer the gas from one side to the other.

 

if im low on gas, ill be sure to take some hard rights lol

 

yay mpg again

average is anywhere from 15mpg to 25-26mpg

 

click on my fuelly link and compare. or you can goto the browse vehicles and look what other people are getting.

 

another mpg thread ... how many of these do we have here ? anybody know ?

 

14,190

 

well searching thread titles for:
MPG gives about 340 threads
gas mileage gives about 195 threads
fuel mileage gives about 25 threads

so prolly around 500-550 threads on fuel consumption...

 

16.9 gallons for series II cars.
I can squeeze out about 400 miles...

 

my avg has been around 240mi / tank. Well, until the light comes on anyway which is usually before 13.5 gallons. mixed city/highway


edit:
And more than one red line a day! haha
