first tank of gas on '07 h3 with auto

[Wu Jen]

My 1st tank = All city driving I got 14.3 mpg. My last tank = All interstate driving I got 17.1 mpg. On a total of 8 tanks so far with the average being 16 mpg. I'm happy.

Can't think of why your getting lower though, unless its air filter related...or speed related.

Get 35's... then you won't care anymore.

I didn't even know I had a light for gasoline.

it's definitely not speed or heavy-foot related. i'll see what it looks like after the 2nd tank. if it's still lower than what everyone got, i;ll bring it up with the dealer. what would the aur cleaner issue be?

I'd suggest monitoring several tanks first (keep a log and do the math correctly), that way the truck will be broken-in. Personally I check my mileage at almost every fill-up and write the calculation (mileage, gallons, mpg) on my Chevron receipt.

Got my 06 H3 in august got my best hwy mpg of 17.5 all highway cruise set at 70 mph with less than 1000 miles on odometer, now with about 16800 my best mpg is 15 on hwy w/cruise set at seventy so after break in mine got a little worse all this with extra weight of winch, roof rack, high lift and pull pall. not sure what changed for less mpg but still get 15 on 20.1 gallons when light comes on so i,m satisfied although it would be nice to see city mileage during hwy driving
