Torque Converter?

[ticopowell]

Thanks for the Advice! I have the inst mpg up on my gryphon and the average mpg up as well, and I usually try and keep an eye on them (havent hit anyone or anything yet lol ) and I am getting a better feel of my truck after having it a little more than a month so far. For filling it up, there are so many gas stations around here I usually go for the cheapest. last time I filled up on base but who knows what kind of quality that gas has... but there are a few shell stations, and a couple conoco stations, but mostly I go to the random stations that are around. Even though my truck only has about 52000 miles should I worry about adding a fuel injector cleaner to the gas every once in a while? would/should/could that make a difference? or would it do more harm than good? Ive never had a vehicle with so low mileage so Im not sure what to expect
I also assume that my altitude has something to do with the mileage, i live at 7258 feet, and the springs is about 6000-6500 feet, so i guess i drop and gain a thousand feet every time I go to the movies...
