| It gets between 14.5 - 17 mpg on highway at 70-80 mph. City 13-16. I put about 3000 miles on a month. My driving is always with cruise on. I was told Cherokees can get in the 20's. That must be at 45 on a flat road! | |

Where are all the previous posts? Did this forum get archived? I used it prior to buying my 07 Laredo 4.7L V8 w/X pkg last Fall and there were a lot of posts here. Anyway, here is what I have measured in 3 sets of conditions after about 2000 miles of initial breakin: 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.

Jeep tweaked the 4.7L for the 2008 model year. The engine now boasts improved horsepower and a slight improvement in fuel economy. Is the latter true? I would love to hear from anyone who has real world knowledge of the fuel economy and performance of this vehicle. I'm going to be buying a 4WD Limited.

Replying to: cmdr17 (Nov 16, 2008 3:33 pm) $2.00 a gallon thats a cost savings of $150/year. I took the 72 month interest free loan so over the 7 years I will save approximately $1050.00 in fuel alone. Plus the new muffler has a nice powerful mellow tone!
