My scanguage II is depressing me

[FJ FunJunkie]

I never realized that I average 10 mpg. even if I barely touch the gas to get up to speed slowly It drops to around 4 to 6 mpg. cruise control will hold me steady at 12 on a flat road at 60mph. I always thought it was at least around 16. Building taller, flatter, wider, and heavier really takes a toll.

It sure does. I'm able to ave. 17-18 on the HWY with my 265s and full armor.

Dude the hubby got the onboard computer on his '08 Titan (actually I got him the onboard computer and the '08 Titan... the man HATES change). He had to turn the thing off because that big 5.6 V8 is just crazy bad on gas. He was not even getting 10 mpg around town and he was MAD!!! He hated the small V8 that he had in his F150 but now he hates the gas mileage. Advice from the spouse, turn that thing off man. You cannot change it so don't get so bummed!!

I disagree, use it to your advantage. Learn what makes a difference. Coasting to lights, drafting in behind other traffic instead of leading the way. Staying somewhere near the speed limit, etc...

You should sell it to me then.

It's not about mileage, it's about smileage!

Good point. Drafting and coasting make a huge difference.

I thought it was a problem with the Scangauge but I get the same! My rig is fully stock except for sliders and I have nothing in the trunk too!

When I first hooked up the scangauge, it showed me like 17-20MPG. Then, when I refilled for the first time...I probably inputted the information on the fillup screen wrong. It's giving me readings of under 10 mph for freeway!

I really don't think it's this bad. Anyone know what could be wrong?

Make sure you guys are adjusting the "fillup" thingy each time you fill up your tank.

Make sure you have the SGII set up properly (tank size, engine info, etc.)
