I checked my mpg on my car because it seemed like I wasn't getting very many and I got 100 miles out of half a tank so according to my calculations that's 13 mpg. Is this typical?

[TheUNZippee!]

Where do you do the majority of your driving? City or Highway?

[hardhitter]

mostly highway

[the real shocker]

my gas gauge reads at half tank at 100 miles and the gas light comes on around 260 miles... and i average 24 a tank

[hardhitter]

All right so I guess that just means that half a tank isn't the same as the gauge reading half

[Garhfer]

no when the tank is full the guage is past full and stuck there forever lol so it's definately more than the guage says

i done mine on the high way and got 28mpg.

[hardhitter]

I just calculated it as 14.8 mpg and the check engine light came on as a small fuel leak. Could this be my problem?

[HMUSN]

leaking fuel probably means your not getting what you should be bro..

[hardhitter]

Yeah but it says it's only a small leak down to .04". I just changed out the fuel pump too for a 255 lph svt.

[HMUSN]

you have a fuel leak and your not under the car fixing it right now?

that serious stuff.. even if it's small.
if you kick up one rock the wrong way while driving.. your toast

[hardhitter]

I have no idea where it is or how to find it.

[HMUSN]

check your new pump for any loose fittings for starters.

[hardhitter]

Am I supposed to use any sealant or anything on the gas tank cover?

[HMUSN]

no

i get 27 on highway and 20 in the city and 380 to a full tank at 14 gallons..and i have an automatic i just rebuilt my self..oh and thats doing 80 mph on 93 pump gas all they way from diberville,mississippi to gadsden,alabama...

Wish mine got that on the highway, most ive ever gotten was 22.7mpg on the highway with cruise set at 75 watching the needle creep from Full to Empty... maybe its time I invest some time and money into installing a CAI + air filter and new spark plugs

I'm not convinced that you know how to calculate your fuel mileage. What method are you using? My GT was averaging 22 mpg in stock form. After the Procharger installation, it has been averaging 17.5 mpg. And that's with setting up the tune a little rich to be safe.

Every time I fill up I always reset my trip meter to 0 and at empty (when check fuel light comes on) I check the mileage and I take the number of miles traveled and divide it by the ammount of fuel it took to fill the tank completely.

That's exactly what I did.
