Got a Jeep Wrangler Hard top 4 door- averaging 12-3 MPG. Seems very low- typically other people say they get closer to 19 city. Could it bet tire pressure? I have roof racks online that's it- not sure but this seems crazy low even for this Jeep- anyone?

A lot of people don't do the math to know what they are really getting. I see this a lot and I tell them how to do it. They were not doing it like this. I'm sure that you know but I have to put it out there.

Best way to do this is zero out your trip meter when you top off. Then next time you top off, wright down the gallons you put in and the miles driven. Use the formula below to calculate your mileage. Then you will know what your getting for mileage.

290 ÷ 10.3 = 28.1
290 miles driven ÷ 10.3 gallons used = 28.1 mpg

@Driven4fun13 -- "Got a Jeep Wrangler Hard top 4 door- averaging 12-3 MPG. Seems very low- typically other people say they get closer to 19 city. Could it bet tire pressure?"

Has it always been "very low"? There could be lots of reasons your MPGs are low.

- A lot of stop and go driving.
- Lots of very short trips
- A failed thermostat
- Two foot geezer driving
- Boy racer jack rabbit driving

The average shown by fuelly.com for recent Jeep Wranglers is 17 mpg. Somehow if your tire pressure was bad enough to lower it to 12 or 13 MPG it would show up in really poor handling.

If it is an older model they only got 13 mpg in the city vs. newer ones that get 17 mpg. Check www.fueleconomy.gov for your specific vehicle.

DRIVEN4FUN13: Have you checked the EPA ratings for your Jeep? That's the first place to start. People tend to overestimate their mileage so most of the time, this isn't reliable information.

Beyond this advice, there's nothing more that can be said since you haven't given us any information to work with.

There are many factors in that such as tire pressure, year model, how the engine is running, and even how it is driven.

Something else you need to take into account. If you drive with reckless-abandon, then you deserve to get poor mileage.

that seems low, but you can try easing on the gas from take offs and start braking earlier to save gas.

Does your Jeep have larger or same brand of tires than other jeeps? Is it a new 2012 or 2013 Jeep?

You can't compare your jeep with others unless it is almost exactly the same.

A lot of factors figure into gas mileage and the way you drive the vehicle.

First, the General Gas Talk discussion category is for general talk about gas stations, fuel, oil, etc. There is a separate and more appropriate discussion category, Fuel Economy, which is for talk about automobiles and fuel economy.
Talk about automobiles & fuel economy.

Second, you're not saying anything about the Jeep other than it's a hard-top four door. You haven't said anything about the year or if you're doing full time city driving, and/or if you're driving in four wheel drive.

Not knowing anything else, if you have a 2013 6 cylinder 4-wheel drive Jeep Wrangler with the 3.6 liter engine and an automatic transmission,you can expect 16 miles per gallon in city driving, and about 18 with highway driving. That said, and yes, tire pressure and roof racks can affect your fuel economy, if "typically other people say they get closer to 19 city", some other people may be rounding up, and some other people may not be taking highway driving into consideration. And still other people will exaggerate their fuel economy (making "guess-timates"). But without your providing more information about your vehicle and your driving habits and road or traffic conditions, for example if you're in stop-and-go commuter traffic in or around Miami, or what your typical cargo load is, anything anyone here can say is just a guess because, while your fuel economy may seem low, (speaking as a Jeep owner/driver) it doesn't seem extraordinary low.

That said, I'm sure your fellow Miami Gas Buddy members look forward to your posting gas prices to help them be more knowledgeable shoppers.

Is you jeep full-time AWD? AWD gets the worst mileage. Secondly, a roof rack is aerodynamically bad for mileage too.

yes check tires, I'm guessing should be over 30 PSI. also try make sure it's in perfect tune, new or not. "check engine" lights don't always tell you a tune up is needed - as in my SUV's case; misfiring, running rough, but no lights came on.

if your Jeeps a 6 cyl your mileage wont be great- heavy vehicle.

Jeeps never get good mileage.
