For those of us with 5.4L 2000 Xs, what products are recommended for increasing mpg and performance. We are considering a Jacob's Mileage Master - has anyone had any experience with these ignition systems on Excursions? Any info is greatly appreciated.
hi, i am the proud owner of an x 2001 with the 5.4 engine. this truck has nothing to envy the v10 engine. i do not tow nothing larger than a jetski, but i can assure you that it has excellent power and great gas mileage. it is a 2x4 and is driven in florida. :-X12
I get 13 - 14 mpg around town, 15 - 17 highway, and
>never under 11 towing an 8000 pound boat.

Man ! What am I doing wrong? Best I ever got was 13 going downhill with a tailwind. I get about 10 or 11 all day, in or out of traffic, freeway or not, loaded or un.
Something wrong with my 10 gunner?
