Replying to: coolrider (Jan 14, 2008 4:39 pm) Very few drivers these days ever consider how they use their vehicles. Oh sure, they have utterances of being environmentally conscious, having concern about mileage and costs but who can honestly say that they have reduced the number of their vehicles or have decided to combine a number of stops in to one trip rather than just getting in the vehicle and going where they want when they want to? What does better mileage have to do with these decisions? Does better gas mileage justify the lack true conservation? I don't think so. When my children were small (30 years ago) I worked as many as three jobs at a time to meet our needs. My wife and I had to make tough choices about groceries, cars, vacations and travel. We understood that groceries, health care and housing came before luxuries. We had one used car-a two door Datson (now called Nissan)710 and it got about 25 miles per gallon. We grocery shopped once a week, I swapped out driving with two co-workers on two of my jobs and I walked to work (seven blocks) for my primary job. The price of gas was less but the real cost was substantially more with my gross monthly earnings at about $750.00. It is not that the gas is high now but rather that we want to use our money for non-essential things and feel oppressed when we have to make adult choices or if we are even threatened with adult choices about when and how we use vehicles. I am sorry but driving a "high mileage car" to make yourself feel superior while owning several computers, DVD players, Ipods, cell phones, multiple and or big screen and or HD TVs, having a carpeted , fully air-conditioned house with all the appliances and 2300 square feet or more is just short of delusional. If folks really want to express some altruistic or some necessary economical behavior, drop the trinkets, sell all but one car and live in a modest house. Having a vehicle that gets even double the gas mileage of another vehicle is a drop in the bucket for the "environmental" cost of your existence. I am not suggesting that it's necessary at all but get real. The best way to save fuel is just to slow down and drive less. |

I have a 07 3.6l larado and I am getting horrible mileage. I can actually see he needle move when i'm just driving around town. I figure the mileage to be about 9-10 MPG. A full tank is only hitting about 195 miles around town. Is this normal and what are others getting?

Seems like you need to have your dealer do some work: any smell of gas (leaks)? are you driving conservatively, ie keep it at the speed limits with slow smooth starts from stop and coasting vs braking a fair distance before a light? My son has our 01 4L I6 and gets 13 in pure in town driving, fairly aggressive but it's got 85K miles and needs plugs this spring. Yours seems very low mpg. |

Replying to: kwteng2 (Jan 17, 2008 11:42 am) After driving home (which I call "city" driving but has 1 mile of freeway,2 miles of 45 mph with a few stop lights and 1 mile of frequent stop/go ... so perhaps it's more suburban than pure city) I was up to 14 mpg in 7 miles. -NET- I am not sure what all that means but I suppose if you have pure stop/go city driving you could be in the 9mpg range around town and have nothing wrong with the vehicle, especially if you are in a cold part of the country with winter warmups and less efficiency too. |

There apparently are two MPG Jeep sub-columns, so let me post this data here that I just put out on the other Jeep Owners: MPG-Real World Numbers. Here is what I have measured in 3 sets of conditions after about 2000 miles of initial breakin on the 2007 Laredo 4.7L V8 with X package AWD Jeep: 1. SE Minnesota winter driving Dec7-Jan12 25% highway/75% city driving using 87 octane (MN requires 15% ethanol in it's gas). 1000 miles 15.8 MPG using the onboard computer. Frequent remote starting with 3-4 min warmups too, so this represents "real life" in northern climates. 2. MN to central TX Jan26-27. Conservative driving at 65-70mph speed limits 98% fairly level freeway with 2 adults and about 400 lbs luggage. 1162 miles 62 gal or 18.75 mpg using actual mis & gallons BUT onboard computer shows 19.4 mpg. 3.Central TX back to MN Feb15-16. Slightly faster driving at 70-75mph, 2 adults and 500 lbs luggage (big storm "chasing" us back, bought souvenirs & too many groceries). 1181mis 64 gal 18.45 mpg $187 fuel costs, but computer showing better again almost 1 mpg better than actuals. So my computer calculated mpg seems to be about 1mpg or 5% better than reality, bummer. However, an interesting point: leaving the midwest the 87 octane gasoline is not mixed with 15% ethanol. (I have yet to try E85 due to our colder than normal hard winter where it runs rough below 10 degress and plan to try some this spring, but it's a known fact you lose 20-30% mpg/efficiency with E85.) I suspected coming back to the midwest gas pumps yesterday with a fill on the southern Iowa border my MPG might drop a bit due to this 15% ethanol ... but no, it improved?! The last 300 miles with this 15% ethanol based gas I got 19.2 mpg actual (20.2 on car computer). BTW, this 07 Jeep vehicle is SUPERB for handling and comfort as well. Compared to our 2001 Jeep it rides MUCH better. I'd get tired in the 01 after a 4 hr trip (it also was a loaded Laredo). I can easily drive this 07 Laredo for 8 hours and even did an 11 hour stint Feb 15, more than the longest road trip ever taken in my wife's 300M which I always considered to be the most comfortable road car we have ever owned. I now have 5600 miles on this 3 month old Jeep vehicle and it's impressing me so far, no problems. |

I have a new 07 JGC 4WD Laredo with the 4.7 V8 that can burn E85 (85% ethanol). E85 is fairly common in the upper midwest although even in our SE MN town of 100K there are only 10 stations that offer it (Iowa, Illinois have quite a few spots, not as much in Wisconsin). I waited until March to try it since it does not start well in below zero temps which we had intermittently during our longer than normal MN winter. I know there is a lot of debate on the viability of current corn based ethanol and I am not a big proponent of that but do believe when/if we get the cellulosic "switch grass" ethanol refinery and distribution perfected we may see real benefits to this alternate fuel in 5 years or so ... and I bought my lifetime powertrain warranty Jeep to last me at least 10 years. Here is an excerpt of a posting I just posted on an E85 forum: I am now on my 4th tank of E85 which has crept up from $2.28 to 2.39 and now 2.49 in just the past month in SE MN. Of course reg 87 gas w/10-15% ethanol has gone to $3.15 and now 3.25. Yikes. So E85 at 2.49/3.25 is 24% cheaper than gas (I got lucky & filled at 2.39 one more time, but corn is going up in price - where is our cellulosic ethanol please !?!?). My MPG varies from around 13 in town to 17 on a hilly 60mph 2 lane road. I got 16mpg  70 mph level freeway that measured earlier at 19mpg w/gas which works out to 16/19 or 16% less than gas. Net: I am slightly ahead with E85, 8% savings or on a $150/mon gas bill I save $12. Not a big deal and still harder to find stations. And some are higher than $2.49 so any advantage rapidly diminishes. It feels good to fill up at $2.39 but you do it more too. If GM and the government would push cellulosic "switch grass" ethanol we might start seeing real reasons to use it but for now with all the subsidies etc I am not in the E85 cheering squad, but not a naysayer either. |

Replying to: steve_ (Jun 17, 2006 1:52 pm) I just changed all the fluids to Amsoil, Motor Oil, oil filter, Trans fluid, front and rear diffs, and transfer case. I've always used Mobil 1 but afer looking at the ball wear test data found Mobil 1 to be at the bottom of the pile. Spent a little more for my Jeep. This is about a 4 mile per gallon increase from last years same trip, the jeep seems to want to coast forever.
