how the hell do you guys get 37?

 

Coasting alot, especially downhill.

I just set the cruise control and go.

 

Happened all by itself, I wasn't even trying. I'm sure I could hit 40 if I tried.

 

The only mod i have in my car is K&N air filter. I get even much better on the premium gas

 

A K&N is highly unlikely to do anything positive for your mileage, and running Premium fuel may even reduce your mileage.

 

when i sometimes fill up when the "low fuel light" is on, the pump will automatically stop around 12-12.5 gallons. the tank is 14.5 gallons. so, in actuality, i still had about 2-2.5 gallons of fuel to spare, right? see, my MPG is probably actually better. if only i knew when i was really close to empty.

see, this is why the scanguage II is a cool device.

Before what I am assuming is full engine break-in back in Nov 2005 we made a trip home to Pa. 1643 miles averaging 33.2mpg. 2.3L 5-sp HB.
Of course I was averaging 27 w/o A/C @ that time. Now w/50k on the clock I average 27 with A/C. She just might do better on a trip these days(?).

EDIT: And Danny, there is are reasons you shouldn't run the tank so low. The old school reason is that you will pick-up any sediment and debris that is heavier than gasoline. The new-school reason is that the electric fuel pump that lives in the tank will not have enough coolant, in this case gasoline to keep it from burning up.
Refill before reaching dead empty is highly recommended.

 

I have a 2008 5-speed Manual iTouring 2.0, and average 32mpg. My daily commute is about 50% city and 50% highway, almost exactly 10 miles in each.

However, if you've ever seen that episode of Mythbusters where they tailgate a semi and get better gas mileage? Well I intentionally tailgated semi-trailers on a tank of gas as much as possible a few months ago, and got almost 39mpg. I don't know how people feel about tailgating them, but it doesn't bother me, my brakes will stop me before their's stop them. Plus it saves me money!

The lowest I've gotten was around 27mpg, I guess I hit a lot of city traffic on that tank.

EDIT: Also to Danny, Consumer Reports did some research, and most tanks stop filling at 80-90% percent, to allow for expansion of gases within the tank. So even when you put in 12 gallons you may have only had another half gallon to go!! I try to fill up before my low level light ever comes on.

 

On the Tailgating, when much younger and moving across country, while I was talking to the driver on the CB since I was close enough that I was hitting the brakes to avoid being sucked into the back of his trailer. I went from Lincoln Nebraska to Wiggens Colorado, at pretty close to 420 miles in a 1972 Ranchero getting close to 30 MPG.
I Don't tailgate now, trusting your own vehicles safety is 1 thing, but trusting the other vehicle is totally different.
