So I used to get 280 miles on a tank and then one day when i filled up it had dropped to only 180 a tank I have looked in to all sorts of thing that could affect it but it burns clean it passed emissions with getting that kind of milage and looking at the results the hc's are normal any ideas?

To my mind, that much of a change can only mean fuel leak. Start with the hoses under the hood.
First turn on the ignition to power up the fuel pump -- without actually starting the engine -- and feel/smell around for anything seeping from pipe-to-hose connections. If nothing, try again after starting. If still nothing, try again immediately after turning off the engine.
All of that, of course, is assuming you're actually putting a full tank's worth of gas in. You'll get a lot fewer miles out of a dented tank, too...
-
No I have checked for leaks fuel pump gas lines. Checked while running too its been a mystery to me for the past few months.
-
What changed.............. tires, gears, any thing, new plugs(1s not firing)somthing had to change along with your gas mpg or you need to catch the guy syphoning your gas and take his wallet then kick his ass !!!!!!!!!!!!!!!!!
-
It's the new gas, try adding 2 bucks worth of Diesel to it per ten gallons of gas it seams to help mine out a little, the more they mess with the fuel the worse it gets, try sticking with mobile or chevron gas, I just took a two thousand mile trip and the cheap gas stations turned out to be not so cheap, I started out with 43 mpg and went down as low as 28 mpg with the same rig, same day of driving, same hwy, just diffrent gas stations.
-
Also, check your tire pressure.
I have problems with the helpful people at the oil change places setting my tire pressure to the "factory recommended specification" of 23 psi. Gas mileage drops to about 22mpg. pump the tires up to about 35 psi, and I get about 29mpg. Rides like a brick, but worth it...
-
It's the new gas,
This is most likely the problem. Ethanol kills mileage. I had a Saturn that routinely got 300 miles per tank. One day, I decided to "save money" and I filled up with the "cheaper" 10% ethanol gas. I got 200 miles out of that tank. Out of curiosity, I switched back and forth to test my findings. It was no fluke. Since then I've stuck to 100% pure gasoline.
pump the tires up to about 35 psi, and I get about 29mpg. Rides like a brick, but worth it...
I keep mine at 30 psi for the same reason, my TracKick rides like a brick, yours must be more like a cement block ;D
-
That has been pretty much the same response that i have gotten everywhere else that i have asked its the ethanol in the gas. Are there any certain gas stations that don't put ethanol in there gas? I have heard about the diesel gas but i was afraid that it would ruin my engine?
-
You can run a good amount of Diesel fuel mixed with gas it won't hurt anything most of the new Diesels run a cat and the new Diesel is ultra low sulfer.

Depends where you are. In MO, after the first of the year, they made it manditory that all gas contain at least 10% ethanol......but they didn't seem to lower the price per gallon any to offset the worse gas mileage you get with the 10% blend.
BTW, I hate 10%.....I tried it years ago (when it was actually cheaper than the regular gas) and it always made the vehicle I put it in run worse and mileage seemed to go down too.
Recently, I have lost about 4-5 MPG, and I am still researching whether it is in connection with the 10% blend or something else that has affected it.

are you serious? :-\
can anyone explain? ???
-
Diesel is less refined than gasoline so it does not have near as many chemicals in it as gas, When you make gas from crude oil it kinda goes like kerosene, jet fuel, diesel, premium gas ,regular gas, and lpg was a by product of making gas that used to be just let out into the atomosphere and like k1 was just dumped some times I have heard early on, maybe some one on here knows more about it.

but youve put it in your tracker?
any damage/pings, etc

I have run it in my sammie for years, It has the 16 valve in it and it likes it, there is injector cleaner and what not in it also, go buy a bottle of injector cleaner and smell it, let me know what it smells like!

Gen-Erix just leave it alone there is not point in arguing I know it was hard for me not to say anything

I do not remember how big my tank is, but I am thinking around 6-7 gallons. If my recall is true, he would be getting about 45 MPG.
The last time I checked, I was getting around 28 MPG, which would be about 170 to 180 miles per tank of fuel.
My idea is that you used to get 180 miles per tank, not 280.

If he has the 11 gal tank 280 miles comes to 25 mpg
9 gal comes to 31 mpg
11 gal 180 miles= 16mpg :(
9 gal =20mpg
witch came with what tanks?
sami = 9 gal???
2 door trackick = 9 gal????
4 door trackick = 11 gal?????
-
4DR kick has a 14 gal tank

The size of the tank is irrelevant, when figuring MPG. Simply take the miles driven divided by the number of gallons of gas you put in to fill the tank........that is by far the most accurate way to figure MPG....not by miles driven and tank size. ::)

Agreed.
To go a step further, log your next ten fill ups and average them. This helps to smooth out inconsistencies in highway/city driving as well as how full you actually filled your tank.
Only problem with this technique is that you have to FILL the tank. :(

Here I can add to the craziness.....
I have been running E85 for 4 or 5 months.
NOT pure E85 mind you. I read somewhere where they took a non flexfuel Tahoe and ran E85 in it for 100,000 miles. Then They dismantled the engine and found a clean engine with no ill effects. I then read about people running 30% ethanol in Minnesota, for a reason I cannot remember, with no ill effects. So I have been mixing the E85 with 100% gas to make a 30% mixture, in both the 95 kick, and 2002 Town and Country. I cannot detect any diffrence in power or mpg in the T&C. The Kick seemes to have less power, but my age old freeway on ramp test shows no diffrence. I might get 1 or 2 mpgs less, but winter time driving really kills my mpg, so its been hard to be sure. Now that the weather is warmer, I will be able to get a true test. Here where I live, the E85 varies between 80cents to 1.20 less than regular gas.
I would be interested in reading about diesel in gas, but since diesel costs WAY more than gas, whats the use?
-
I hope somebody figures it out,cause I am down about 5 mpg lately.No leaks,kick still runs great.i want my mileage back.
-
Is any of this possible from a faulty EGR system and/or bad 02 sensors? My mileage has dropped too...yet the truck drives great. I now know my EGR valve was stuck open so the truck ran really rich, and since i can't figure out where the tubes on it go i can't tell you yet if the new EGR fixed the problem or not.
-
I have been checking my mileage every time i fill up it has gone up to about 19-21 mpg so it has gone up but not any where close to what it used to be. my tank is 10.5-11 gallons
-
my 4-door auto 2wd always gets about 23-24mpg
i think 2-door manual 2wd gets the best mpg as ive heard claims of up to 35mpg
-

It doesn't take much idling in traffic, driving against the wind or running the ac more often than before to blow 5mpg.
Edit: Okay, 5 is a bit much, I guess.
I just picked up almost 2mpg by...finally...airing up my tires.

Yes both of those items will cause problems. Remember that EGR is only supposed to come on while crusing. A EGR valve that sticks open will cause the truck to run lean because it is letting more "air" into the combustion chamber. This can lead to detonation at lower speeds. The O2 sensors job is to tell the computer how much O2 is in the exhaust. That is how the computer determines how long to fire the injectors for. So if your EGR valve is stuck open the O2 sensor will read a lean mixture and tell the computer to add more fuel. Also if the O2 sensor is old and always reads lean then you will be running rich all the time. On the 8 valves the EGR passages run through the intake manifold and the head. Not to sure about the 16 valve though. The best way to find out would to put a scanner on the car and watch the data stream from the computer.

Diluting gasoline with any amount of ethanol will reduce power and increase consumption.
Unless the on-board computer can adjust timing and compression to compensate for the lower amount of power in ethanol.
-
Ya ethanol is the biggest scam since carbon credits. So the egr valve is where on the samurai? I think i have been mistaking it for the pcv valve. Maybe i have over looked that part of the emissions line up. How much would it possibly affect my gasmileage if it were bad?

It smells llike you're paying around $48.00 a gallon for diesel. :o :o
If it's truly diesel, at around $6.00 for a 16 ounce bottle and 8 bottles 128 ounces = 1 gallon) to a gallon. I'll never buy fuel injection cleaner again if all you get is 16 ounces of diesel.
Thanks for the tip!!

Exhaust does not contain significant amounts of O2, an EGR stuck lets hot exhaust into the cylinder, which raises the charge temp and could cause pinging, also because the exhaust doesn't support combustion it will effectively lean out the mixture also causing pinging.
