Getting Better Gas Mileage

My truck tends to get about 17 MPG in my typical week. I tested this numerous times so it should be pretty accurate. With one of my last fill ups, I decided to try a few things. First, I put in some gas treatment before I filled up (a suggestion that Dan gave me). I then modified some of my driving habits, particularly trying to speed up slowly (keeping the RPMs lower). When I refilled the tank I calculated out my gas mileage and it was about 19.5 MPG. I would classify that as a pretty good improvement.

These changes amount to about 40 extra miles per tank and about $10 per refill (assuming $4 per gallon and adding 16 gallons of gas).

I am going to try and stick with these driving techniques...especially since the MPG that I get is already below 20.

Note - I am not taking this so far as to drive everyone behind me nuts by speeding up extremely slowly or merging in to traffic at a dangerous speed. Hypermiling is the proper term for some of that and I think some people take it too far. Hypermiling in and of itself is ok, but going to the extreme can be dangerous.
