OMG My Gas Mileage!!! General Question Need Everyones Help

[Joe Isuzu]

No worries Lizardmen, I'm not that much better and I have ZERO power mods to the VX. I get basically 16-17 mpg, if I get 18 I'm thrilled. I have no dreams of getting 20 or above. I don't know how some of these other guys do it. Yes, I use constant throttle pressure, very limited brake action, always in 4th when I can help it, rarely goose it around traffic and my mileage still stinks. Oh well, I knew gas mileage was one of the faults with the VX. At least we get to use regular gas!
The only thing I can think of in your case is to make sure the tire pressures are good, if one is really bad or more than one are kind of bad, that would be a cheap and quick fix to your problem. Especially given the large size of these tires. Good luck!

seafoam gas tank, oil, through pcv. check spark plugs, o2 sensors, injectors. Clean egr, throttle body. Change fuel filter, drain a little from the bottom of your gas tank.

Check your brakes maybe they are not releasing completely,check egr valve it could need to be cleaned or replaced and check your intake gaskets.Just had my intake gaskets replaced and all my problems went away,bad mileage,bad idol,exaust smelled rich.

i think the 18" vs 16" wheels have a lot to do with it. i bet most of the guys with the higher mileage are running 16's with stock tire size.

your 285 60 18's (i run the same size) are heavier than the stock 245 60 16's AND considerably taller. remember the profile number (60) is not a direct measurement, it's a ratio that depends on the width.

i think the speedo is off by 6% with my terra grapplers of the same size. and most of the extra weight is now located further from the center of the wheel, which requires much more enegy to rotate.

16mpg combined on stock 16s with a pv muffler.....

[18Foxtrot]

New, 21mpg with everything stock. Now, 19mpg with K&N air filter, Bridgestone AT Revo 265/70SR16 tires and Mobil1 oil, changed every 3000 miles. Everything else on the engine/transmission is still stock.
