#56 of 102 Re: Gas Mileage [marty21] by reholmes Aug 23, 2007 (7:57 pm)
Replying to: marty21 (Jul 28, 2007 7:02 pm) Took my 05 GCL Hemi with 20k miles on a recent trip to LA, returning I got 20 mpg from Oxnard to Palm Springs driving about 70--the speed limit--and up and down the hills, etc. Today, I drove from Phoenix to Sierra Vista, around Fort Huachuca and returned via the wine country in Sonoita keeping the Interstate speed at 70 and around 60 on the mountainous state routes--20 MPG. There may be some things that Jeep could have done better, but it's not the Hemi's gas mileage. OBTW, there is nothing that can beat it off highway in the desert canyons--nothing!

Replying to: naatz1 (Aug 23, 2007 5:33 pm) A Saturn Outlook, Hyundai Veracruz Highlander are simply not in the same class or capability of a 5.7 4WD Grand Cherokee-different vehicles for different applications. They are no more gas efficient than the 5.7. Do they get better mileage-sure they do but not because of more efficiency but rather less capacity.   I don't understand complaints about gas mileage. I get 22+ m.p.g. with my 2006 5.7 on the highway. Around, anywhere from 14 to 18 depending how quick I want to go. I am paying for the capacity and capability. If my primary concern was gas mileage, I never would have bought it.   By this day and time, anyone who thinks E.P.A. estimates on window stickers are accurate must have been in a coma for years. However, there' not a car out there that does not have numerous reviews about gas mileage. How could anyone not know?   Why would anyone blame Chrysler for E.P.A. estimates, they are required by law to post, which indicate gas mileage for a group and clearly states it will vary by many factors?

Replying to: podedwards (Aug 23, 2007 8:12 pm) There are vehicles of like type and engine configuration that simply get really crappy mileage, While identical others get really good. Even with the same driver. There are so many sensors, switches, inputs, etc involved with the fuel delivery and corresponding power output that modern day tune-up technicians can be overwhelmed.   In a nutshell, if they don't see an error logged on the computer, or if they don't have past experience on a particular problem, or if no help in the form of a TSB is available, they are stuck!   "Your car checks out OK. You will need to put 20k on it before you can expect to reach the EPA numbers."   Of course they are hoping we will get use to the poor mileage or trade cars. OR develop better fuel efficient driving techniques.   My wife has an 03 Honda CR-V. She averages 20-21 MPG locally. When I drive it, the average is more like 23-25. Simply stated it is different driving styles. Most people don't realize how many times we touch the brake then the gas, then the brake, and so on in local driving. Each time we do that we are either burning extra fuel or have been burning fuel needlessly, resulting in heavy braking.   I've talked with people with late model Dakotas, Grand Cherokees, and old style Durangos with the 4.7L that were getting much worse mileage than my larger heavier 98 Ram with the 5.9L. Right now, I'm driving an 03 Honda Pilot. (I'm on this forum because I'm considering a Jeep GC with a higher towing limit than the Pilot).   This is an example of poor mileage and good mileage with the same car. On a Trip from Atlanta to Myrtle Beach, the cruise set at 80 mph, and AC on full time with 4 people and luggage we got 18+ mpg. On the return,trip the next day, we ran at 65 mph, the cruise was only used on relatively flat terrain, and the AC (Compressor) was turned off when it wasn't needed. That yielded 26+ mpg. Understandably there could have been slight discrepancies in the way each tank was filled. A gallon more or less would have possibly yielded 19 going and 25 returning. Still a big difference.   Some people have a natural knack for getting good mileage. Obviously "podedwards" has it. Every engine and drivetrain configuration have "sweet spots". If we stay in them, and observe common sense MPG driving techniques our mileage will be better than if we don't.   My neighbor just bought a new Honda Ridgeline. With a few hundred miles on the clock, he went to Florida. He was disappointed in the 20.01 mpg he got. Especially since the Ridgeline and Pilot are within a few pounds of one another and the gearing is the same. As it turns out, he was running 75 mph with full AC and cruise. He was out of the "Sweet spot"!   Axle ratios can be misleading. A car with a 3.73 axle and 17" wheels can actually have an effectively higher ratio than one with a 3.55 and 16" wheels. Then the transmission ratios can also differ. The only way for us to tell is by driving different configurations and see how many RPM the engine is turning at a given speed in a given gear. Example: At 60 MPH my Pilot is turning about the same RPM with its 4.428 axle as the Ram did with the 3.55 axle.   Kip

I'm getting 15-16 in town and 21-23 on road with a 4.7, marty.
#60 of 102 2007 GCL V8 by hodget Oct 03, 2007 (6:12 am)
At 1600 miles we are getting 17.8 MPG. in a city and highway driving mix. Will be changing to a synthetic oil at the 6000 mile oil change.
#61 of 102 Re: Terrible Gas mileage [offer] by tsfromtx Oct 10, 2007 (7:55 am)
Replying to: offer (Jun 17, 2006 12:25 pm) My '07 GC with 4.7 V-8 has about 11K miles. Now that it's broken in, mileage isn't that bad. Only about 13.5 mpg around town; around-town traffic in Arlington Tx is horrible. Mixed city/freeway is more like 16 mpg. I get consistently 20 to 20.5 mpg on interstate driving at 70mph (I drive with a light foot & avoid hard acceleration). Pulling our 3,000 lb camping trailer, we get 15 mph on long trips.   My Jeep has a trip computer. For the first 6K miles, I checked every tank with a calculator. But computer is close to accurate - it consistantly reports 0.5 mpg better than what I get by hand checking, so I just rely on the computer now.   Overall, my observations are that the GC gets decent mileage if you are a disciplined driver; the mileage drops rapidly if you're prone to jackrabbit starts or frequent use of passing gear.
#62 of 102 diesel grand-cherokee owners in the hizzy? by elias Oct 11, 2007 (7:15 pm)
speak up diesel cherokee peeps! real trucks don't have spark plugs. seriously now, how are your diesel grand cherokees doing on mpg especially once they get >10k miles.?? maybe there just aren't enough of you folks out there, or you are cranking out so many miles per year, you don't have time to post?
#63 of 102 2006 Jeep JGC gas mileage by kpsra Oct 31, 2007 (8:17 am)
First 1/2 tank I got 13.65. 5.7L Hemi, dealer told me that gas mileage would be about the same as my traded in 98 5.2L. Does anyone think that using 93 octane would increase mileage? I currently use 89. What about acetone to increase mileage? 4oz per tank? Replies to this message: reholmes (Oct 31, 2007 8:53 am)
#64 of 102 Re: 2006 Jeep JGC gas mileage [kpsra] by reholmes Oct 31, 2007 (8:53 am)
Replying to: kpsra (Oct 31, 2007 8:17 am) I have had five GCL and all have gotten about the same mileage--I get about 17 with mixed driving and often over 20 on the road. Having said that, I have a very light foot--real tempting to jam the Hemi and scald the jerks in the Acuras. I have always used 87 octane. Am presently using full synthetic 5-20, but can't get Chrysler to commit on a full syn oil recommendation.
#65 of 102 New 2007 4.7L MPG by naatz1 Nov 11, 2007 (5:28 pm)
Using the trip computer on my first tank of gas at 302 miles I am getting 15 mpg in 100 mi's of in town average. I got 21 mpg 60mph for 20 miles of rural highway last night. This is with fairly conservative driving, no AC, usually only 1 person in the Jeep. The sales rep said expect it to increase a little after 2000 miles, also to watch E85 ethanol usage in winter temps; I was tempted to do a E85 fill today with temps in the 50s but in MN that won't last.   I will post more results in another 1-2 months after vehicle breakin but so far this is about what I expected with a small V8.
