Fuel problem
 
Burning fuel really bad. This started happening all of a sudden. I think I might be loosing fuel somehow even though there are no puddles on the driveway. Any suggestions? Just changed oil too.

Burning fuel? Like, poor fuel mileage?

tsteb 02-15-2013 07:20 AM

Yeah. It's going down a lot faster than normal. The gauge. I used to get 240mi on one tank and now I get 180mi per tank. Same driving habits.

replace your up stream o2 sensors

I noticed the same thing. I thought it was my jeep until I noticed my girlfriends car (toyota corolla) doing the same thing. It has to be the gas... It's a conspiracy.. Just kidding but not really

Winter gas? Where are you at?

Try running a tank of non-ethanol through it too. It's better for the older engines than this crap E-10 stuff they're selling us now

Patrick H 02-16-2013 11:21 PM

Around here, at least, you can't buy gasoline without 10% ethanol.

PStov98TJ 02-16-2013 11:27 PM

That's no fun. I live in Mississippi so there are still a few mom and pop gas stations that sell it. It's more expensive but because I have to leave my Jeep sitting at home for a long periods of time while I'm away at school, the non-ethanol is better for it. And after I started running non-ethanol in it, I noticed a slight increase in gas milage (like 1 mpg maybe) and it definitely runs a little smoother. Just my 2 cents

I get a bit better mileage with the non ethanol gas, but not worth the extra .10 a gallon. Stupid question but are you doing any extra idling? Letting warm up?

tsteb 02-17-2013 08:39 AM

Not much. I let the oil pressure come up and then I put it in gear and start going.

Patrick H 02-17-2013 09:02 AM

I let mine warm up for usually 10 minutes every morning from October-April (I don't like getting into a cold vehicle ;) ) and even with winter blend fuel I'm getting right at 16MPG in town.

What's your secret??

tsteb 02-18-2013 07:41 AM

Haha x2 on how to do that

Pesty15 02-18-2013 08:35 AM

I am having the same problem with gas mileage. Where is the best place to find the upstream o2 sensors for relatively cheap.

KingTJ 02-18-2013 09:10 AM

Rockauto.com.. I bought mine there for a fraction of the price that others are offering them at!

I don't keep any secrets. Last week I checked @ fill up, and was at 16.08. The fill up before that was 15.6. 32" tires, 3.73's, 5 speed, and my speedo (odometer) is about as dead on as I could ask for, according to every radar speed sign I've driven past, and we have quite a few.

scott howard 02-18-2013 09:21 AM

Only buy oem or ntk o2 sensor . you can find them on amazon for really good deals

tsteb 02-18-2013 10:24 PM

Is this a do it yourself job or should I let a shop take care of it?

Replacing o2 sensors? Easy enough. Easier than changing spark plugs.
