Milage in Colorado

[johndjmix1]

Im begining to think somthing is up with my H2. No matter how gentle i drive i cant get the MPG over 11. And trust me, i know how to drive gentle and get good mpg, i got my ford expedition up to 17 in NY...

The real thing that makes me wonder is, if i drive normal i get barley any improvement in MPG. Also, the engine is very loud (sounds like the clutch fan?) when accellerating, espically with the A/C on. Power also seems low. Worst on hot days.

Is this normal? I want input from colorado people since i know out here mpg is way down from what we would get out east.

I know when i got my H2 it was doing much better. And yea, i checked the air filter....its clean.

Any ideas guys?

My life-to-date mileage is exactly 12 mpg. In this thin air, the H2 is a bit underpowered. Any time you go up a slight incline it shifts down into 3rd, and often 2nd which winds the engine like crazy. I drive up I-70 to Evergreen almost every day and spend 1/2 of that time in 2nd gear at 4500 rpm. I've added a rack, winch, and 200 lbs of underbody protection. The more weight you put on it, the worse it gets. Adam's loaded rig probably hasn't seen 3rd gear in 12 months!

Are you running your A/C all or most of the time? That sound you are reffering to is your fan clutch, it comes on to bring down the engine temps, and will come on quite a bit more when the A/C is on. When the A/C and or fan clutch is on it will suck down a decent amount of power. Enough to make a noticable difference, and will knock your MPG too.

I get 32mpg.

Actually, I found with my stock H2, running Breckenridge area, I got around 15 MPG no matter what. Here on the East coast, I have to be light on the pedal to get 12MPG. So I experienced a milage increase out there.

Were you going down the ski slopes when you were getting 15mpg?

John, does the roaring fan stop roaring at just above 2000rpm? i.e. is the fan clutch releasing or not? You can tell more easily when parked. Slowly increase throttle in park and see when it stops. If it's really noisy and you can't tell, you might need to lift the hood, stand on the rocker and watch it as you press the throttle and watch the RPMs.
