Re: 4.7L gas mileage...

Hello newbie here chiming in With my 4x2 Grand Cherokee Limited im getting right at 17 in town and upwards of 23-24 on the highway, I run both Lucas and Seafoam about every 7k miles through the system to stay on top of these marks. Some might say different, however the numbers dont lie 325 to 350 miles a tank. Reground Cams and home-made CAI.

Re: 4.7L gas mileage...

Yup, about the same for me even with the slightly taller/wider /more agressive tires. 12 to 14 every day driving, 19 to 20 all highway.
