Re: How low can you go....
By far the single most effective mod to improve mpg was to increase tire pressure. I now increase to 48psf on long highway trips (from regular 42 in city), and get maybe 1mpg better, without changing my driving style (pedal to the metal
).

So, on a hot day, running the x-ways, you are hitting approx. 52 psi in your tires? What is the max pressure labeled on the tire?

Re: How low can you go....
I hit 395 miles the other day and probably could have gone further....but I chickened out. Turns out I put in 21.6 gallons at that fill.
Does the H3 have a 22 or 23 gallon tank?
oh yea, I have 26K miles on it adn the mileage definetly got better after about 8000 miles and continues to improve.
