Better Gas Mileage?

[matt5112]

lol at what this thread has become.
I get 25 MPGs... and i drive it like i stole it.

Thats impossible.

But continue to amaze us with stories of your brochampionship.

[E IN v Y]

I can prove it.

[matt5112]

25 mpg or that you go wot every time you touch the gas?

seriously had it with GP owners claiming they're "hard on their cars" then get amazing fuel economy.

Just doesn't happen.

[indygrandprix]

and most of it wont do anything.

Use seafoam or STP complete system cleaner or best of all: GM fuel system cleaner.

If you don't want to pay 20 some bucsk for GM fuel system cleaner Techron Fuel System Cleaner made by Chevron has almost the exact same chemicals in it. Its like 12 bucks

Well my DIC is wrong then i guess.
You win Matt.

Yeah, its the same thing, but as to where you'd find it out here, I cannot say.

Damn I feel bad. I get a little better than 200 miles a tank city and 350 on the highway. I am running slightly shorter tires and cooler tstat. I'm about to swap back to a stock Tatar and correct size tires. I used to pull 30+ on the highway, now I'm around 27 the last time I was on the highway.

[dbextreme]

Let me know if that Tatar helps and where you pick one up.. I might need to get one myself..

they're all around 17-18 gallons.

Not sure why mine is not 17-18 gallons. From E, it takes around 13 gallons to fill up.... and that is fillng it after several "clicks" off.

[Sandman]

It'll help some I'm sure, the little stuff I've done to take my MPGs down add up so I'll do some stuff to bring it back. Plugs and fuel filter as well.

Your fuel gauge is wrong then.

Your tank is just as big as mine. 17 gallons.

all gauges are a bit different car to car. but also keep this in mind, when the low fuel light comes on, you should have 100 miles of travel left in the tank, so there's 3 or 4 gallons right there in the bottom of the tank.

ive also noticed in my regal it only takes 13 to 14 gallons to fill it up from E.

Yes mine is 13 gallons from E, it always has been.

[Adidasdude1989]

Maybe different sub models the tank size is different? Possible?

i thought i just cleared this up.

every car has a reserve of 100 miles in the tank when the light comes on, thus leaving at least 3 to 4 gallons in the tank when the light comes on. 4 + 13 = 17 last time i checked. we all have a 17 gallon tank. plus the fuel lines and filler neck.

[Fivefingerdeathpunch]

You have a 17 gallon tank, read your owners manual lol.

[GTP in RTP]

I thought our tanks were 18 gallons.

[silvapain]

It's 17.5 gallons according to my 2002 manual, page 6-74.

Left to right, top to bottom guys.

Fuel level senders are simply a potentiometer connected to a float. They never have been very accurate. A better way to check distance left to empty is to always reset the trip meter every fuel up.

On the highway I can get well over 400 miles on a tank without using more than 16 gallons.

Well then i guess i should stop freaking out in a middle of a drive when my low fuel light comes on. I know the most ive ran before putting gas in was about 317. I always assumed it was 13.5 gallons because of filling up after 317 miles and it would stop around 13 gallons. I usually avoid the low fuel light and under the quarter of a tank line is when i put a little bit back in to over at least half a tank.

I did get some Pro-Gard fuel injector cleaner with techron additive for about $5
