Time for an MPG update

[alrock]

Greg, I thought your rig was ON cinder blocks right now

 

[MaxPF]

Nope. It needs a lot of TLC, but it still runs for the moment.

 

[M22KLARS]

18-19MPG city. Rig is on 37's, weighs 6300lbs, and has the aerodynamics of a cinder block

Wow that's damn good for that beast.

 

[crank]

No matter what I do.... Never fails.... Highway/City.... 11.5 mpg on my H2.:sigh:

 

[MaxPF]

Wow that's damn good for that beast.

Yup. When I first lifted it and put the 37's on it was still running a fuel-injected 350 and got 10-11MPG. Thats why I swapped in a diesel

2008 H3 5 cyl 16 city 20 highway!

 

[SolidusJ]

09 H3T 3.7L
16 MPG everywhere
285's

That's with the PCM E-fan kit and tune and a whole lot more things to kill my MPG!!!!!!!

 

[08SolarFlareH3]

Just filled up the other day and calculated MPG. All short drives, lots of stop and go. Also the 2 mile drive to work and 2 mile drive home kills gas mileage.

264.7 miles x 1.03691 (difference in tire size) = 274.47 actual miles / 20.7 gallons = 13.25 MPG

08 H3 w/ a 3.7L & AT and 33x12.50 mud tires

 

[06 H3]

My mileage hasn't been the best I need to get my pcm tune to get some back

On my trip to South Bend IN in May from Montreal to South Bend my Alpha averaged 23.53 mpg (10L/100km) on cruise control at 68mph. (110kmh) I was very pleased, since my 2 previous H3's (06-09) I5 MT, I was averaging 19.60 mpg (12L/100)

Right now im running stock 285-75/16, with OEM UCP and rocker protector.

I have been checking my mileage....just got an alignment, it was out from the factory, and installed a K&N drop in filter. Doing about 16.5mpg right now. I'll check it again on the next fill up. 09' Alpha

 

[alrock]

I had a trip this month where I did 80-85 for nearly an entire tank on winding, moderately hilly two lane road. Averaged 13 mpg, down about 3 mpg when I take similar roads at 65.

2008 Alpha 33.1x12.3/16 BFG km2's with h3t steel wheels. I think when i switched to the steel wheels i lost a little mpg, could be wrong. Superchips flashpaq set on 88 octane tune, magnaflow exhaust.

Average City- 16-17
Average Freeway- 18-19

It always varies due to # of times i start the car, idling time, etc. Those #'s i can get pretty consistantly though, can't wait to see how the gobi stealth effects those numbers. :giggle:

 

[FormerUser]

Last tank was 267.3 miles, all city driving. 14.1428571mpg. Kinda crummy, but at the same time it took me three weeks to log 267 miles.

 

[M22KLARS]

Yesterday I put away the toys and today I started using my H3 as a daily driver again. I'll report back in a week or so.

I wouldn't be surprised, the steel wheels are noticeably heavier then the alloy wheels.

 

[WarMongur]

Mine is a daily driver, so this is city miles with the following components:

2007 I5, Front Level, 35's, OEM light bar, OEM roof rails, PCM tune, AirDoc, K&N filter, 87 octain fuel, and I drive it like a BMW .... a whopping 11 MPG average.

 

[M22KLARS]

According to my SGII I've been averaging 13.5 per day... We'll see when I do that math at the end of this tank.

Every time I get around to calculating MPG's space aliens abduct me and erase that part of my memory. They tell me they are my friends. I think they might be right.

 

[SolidusJ]

I wish I could get 18 MPG.

 

[Hunner]

I got 15.7 with a 40-50 mph tail wind as indicated on the digital display on the side of the road.:shifty:

I still think it is that giant electromagnetic sterilizer you have on your roof that is doing it.

:giggle: Well how do you think I communicate with the aliens in the first place?
