Milage Increased ALOT all of a sudden
Not that I'm complaining, but my milage shot up significantly about four tanks ago. It's up to 23.0 mpg. Granted, this has been 95% highway driving. The first two tanks I was driving between 60 to 65 mph, the third tank was right at 65 mph, and the fourth at 70 mph. I do drive for milage (shift at or below 2000 rpm, etc.), but really don't understand why the milage suddenly shot up. Before this, my truck was getting 20 mpg. The only thing that I changed was teh air filter (stock filter just put in a new one from AutoZone - DuraLast brand ???). Could this be it? BTW, my truck has 40,000 miles on it.
For all you non-believers, I have kept track of every ounce of fuel that my truck has consumed since day one. The last four tanks were consecutive - 2718 miles w/ 118.0 gallons consumed!

If a better or no restriction filter is all it take to get that kind of mileage then why didn't mine with a fan pushing air into the motor? I never had negative air flow, positive flow most of the time.

If it's really that bad I'll buy your truck and you won't have to worry about it. My guess is you got one of the exceptional trucks that the odomiter is off some or a lot and you go less miles than it shows so it gets great mileage. Or maybe the computer is messed up and actually letting the motor run at its optimum effeciency. Man if someone could use your truck for a test vehicle and then set everyone up like yours.

Second of all, the calculation is hand calculated and based on the odometer. However, it is 'confirmed' by real distances travelled - been from bouncing back and forth from VA to Ohio as well as going up to Boston.
I'm not trying to convice anyone of anything, but do know that my data is accurate & real.

I only did one mod - the tone ring mod to advance the timing. This was done 20,000 miles ago. Seemed to help milage, but only by .5 mpg or so. Other than that (and the 315 tires - which was a break even prospect from a mpg perspective), my truck is a stock 6 spd. 4X4.

I bought my truck used and it still had the original factory filter in it. The minder was pulled down about 1/4. I put in a new Wix filter, with a higher flow rating, and swiss cheesed the air box. My highway mileage went from 18 up to 20 mpg with this change. So yes, I think a better flowing filter may have helped you. Was your minder pulled down any before the change?
