2009 H3T
I-5 3.7 L Auto Tranny
Less than 1000 miles on her at this point
Avg. MPG combined thus far on 2 tanks of 87 Octane = 12 mpg
Leveled with BFG TA/KOs 295/75/16

*My prior 2006 H3 (3.5 L I-5 Auto) consistently averaged 15 mpg around town and 20 mpg highway.

 

Just got back from a trip and here is what I got:

I5, Manual, leveled adventure.

Driving 80 with 400lbs of gear - 17
Driving 65-70 w/ no load - 19-20
City - 14-15

I drive spirited most of the time.

 

2009 H3T with the I-5, I have 25,000 Mi. and mostly all highway. With the stock tires I was getting around 16-17 mpg, But with the new tires, I'm hovering around 13 Highway. I was kinda surprised I was getting that much off the lot though.

 

2009 H3T I-5 Adventure Pgk, 4500miles avergage is 17mpg, next week getting it leveled.

I used to get 14mpg in my Titan

But I sure like my H3T!!!

 

Alpha

Since buying w/ 4k miles on it in November 2009:

Avg MPG - 14.27
Max MPG - 16.18
Min MPG - 13.02
Total Miles - 10,788
Cost / mile - $0.18
Miles / $ - 5.56

I keep track using GasCubby for the iPhone. Great app.

 

Yawls city numbers are a lot better than mine, Ive got the T with Alpha pkg and no suspension mods or new wheels (stock 32s), and Im getting around 10mpgs city; but thats also drivin in New York City and most of their traffic lights are not synchronized anymore.

Im getting over 20mpgs Hwy now since getting the Air Doc and Diamond Back cover installed, if I dont set the cruise control over 50.

My I-5 Manual is great on gas... I can drive from Calgary to Vancouver on a single tank of fuel (600 miles).

City Average: 16-18 MPG
Highway Average: 20+ MPG
Extended Trip Average: 22-24 MPG

Sugarphreak's HIGHWAY TIPS: Use Cruise Control on the highway; keep your tires inflated around 38 to 40psi; for manual transmissions don't strain the engine in 5th on steep grade hills, you should be gearing down to 4th for more power and better fuel consumption well before you start to lose speed in 5th.

 

Are you sure you don't mean 600kms? if it is 600 miles you would be around 30mpg? I drive alot on the highway and I average about 21mpg.

 

^^ No I mean 600 miles... that trip is 1000kms

I averaged between 22-24mpg (US MPG)

Keep in mind the H3T has a much larger gas tank than the H3 SUV
