WJ Jeep Grand Cherokee sucess, is relative aparantly
Hey guys, I just wanted to gripe with some folks who'd understand.. For 2 years now my wifes complained about her Pontiac Sunfire and how she wants a Jeep SUV. So I traded off her Sunfire for a 2000 Grand Cherokee Laredo, 6 cylinder + 4 speed auto & 4x4.
Serviced the diff's with synthetic 80W90, trans with synth ATF+4, engine with synth Rotella oil, new spark plugs, intake cleaned out, fresh air filter, removed roof rack and 35PSI in the tires.
EPA is 14 City, 19 Highway. ACTUAL is 16.2 City, 22.8 Highway.
To me thats awesome gains considering there's no aero, no retuning or anything else just maintenance. To her its "terrible".
Its never occured to her going to an engine with 2 more cylinders, double the capacity, a 4 speed auto instead of 5 speed manual, extra transmission (tranfser case), two more driven wheels and extra 1500lbs of vehicle might have a negative effect on fuel economy.
The good news is, she's a bit more interested in driving efficiently now. So on the road trip yesterday we discussed and practiced drafting techniques and picking smoothest lines and such.
