The best way to gain MPG is to drive the speed limit if you have a 4 speed because you have only one over drive gear. While 6 speed trucks can travel faster because they have 2 over drive gears but get equal MPG. On my 96' I can get 21MPG US on the highway when going 55, but I lose like .2 MPG per every MPH faster I go.
Warning to the starter to this thread sometimes they can get very opinionated.

My z71 was getting 16.7, it was depressing for a while, untill I saw what others were getting around here, I did switch to nitro fill in my tires, I was not fishing for better mpg in doing so,I did it becaue of all the perks that come with that. however it did make an improvment. same tire pressure, 35 psi all around on the factory 18's, my mpg went to 17.1. that is not huge, but it did give me a happy face. I cant swear nitrogen in the tires did it, but that is the only change I made in the past two months other than wheel well liners and some graphics, I would sound like a whack job giving the credit to those, lol.Life is short compared to history

I started running Tc-w3 marine 2 cycle oil in my fuel in March. I add one ounce to every 5 gallons of gas. The truck runs and idles smoother than it ever did. The slight fuel pump buzz I had is now gone. The oil is supposed to lube everything, fight corrosion, and clean the ring packs. I was getting 15.4 mpg in the city before I started using it. Now I get a consistent 17.4mpg in the city. My dad started running it in his Avalanche and Saturn Vue last month and has also noticed a smoother idle and increased mpg. I just bought a bottle of injector cleaner and dumped it into my wife's van. Then I poured one ounce at a time of the Tc-W3 into the bottle marking each ounce with a sharpie on the bottle. I started with a fuel tank of gas (31 gallons) and dumped 6 ounces in. If I stop and put 10 gallons in, I dump 2 ounces in and refill my bottle when I get home. Like I said I have been doing it since March and have not finished my first gallon of oil. I stopped using it for 2 tanks of fuel because I thought I screwed up my mixture. My mpg returned to 15.4.

I know people will argue with me, but the best way to get better fuel economy is to use the friggin cruise control. This is especially important on long trips.
People will blab that they are "better" at controlling engine RPMs or "I want to be in control", blah, blah. Studies have shown using cruise control can net people 7-14% better fuel economy. Cruise is on there, you paid for it, use it.

The only thing I really do is keep my tires aired up. I run 45 psi in my tires and I have noticed about 1.5 mpg gain over the recommended 35 psi.
I'd definitely like to hear more about this 2-cycle oil in the fuel.Clint (TX) 2001 Silverado LS 4.8L auto 2wd ECSB [GARAGE]
