Message: [QUOTE="Turbosuzuki, post: 1527895, member: 5973"] OK guys any info on how to increase fuel mileage. My truck seems to really suffer in this department. I'm no mechanic but I can change some parts as long as I can watch a video on it. Truck is a 2001 7.3 4x4 and it's gets about 95 miles to a 1/4 tank. It gets under 400 to a tank. I need to do a full tank and calculate it but I feel it gets horrible fuel mileage. Truck has a tymar intake 4" exhaust with a huge muffler stock tunes 3.73 gears 285/75r16 tires with 65psi front and back. Oil which is valvoline has about 1700 miles on it fresh fuel filter also. I just replaced the ebps and tubing with no noticeable results which suck. I drive 65 mph when I do 70 mph it kills the mileage quick so I try to run between 60-65. Truck seems happiest at that mph also. Oh the hubs are locked but would that make that big of a difference? The increase in tire psi made the biggest change so far. I'm fixing to do another oil change maybe try something another type of oil. I baby the truck plus it's REALLY slow and it just made 272,000 miles. Thanks for any help or advice [/QUOTE]
