Didn't think this MPG was possible

[paddlenbike]

I'm not sure why people are calling bs on this thread. The stock MPG for a 5-speed is 17 city, 20 highway. I always got 21-22 MPG when stock. Now that I'm lifted, big tires, supercharger, etc., I'm down to 19.5-20 MPG. It's entirely possible, even with having some fun on occasion with the skinny pedal.

Getting over 20 mpg is very possible in a stock truck.

However, the method the OP used to get the 24.3 mpg figure is not reliable. You need to take an average over a greater period of time and miles. How do you know that you filled up to the exact same point in your tank? With that small of a fill up, even a half gallon difference between fill ups will throw your mpg number way off.

To put things into perspective, if you were to get 24.3 mpg over an entire tank of gas, that'd be 418 miles before you run empty!

Sorry for the delay. Everything on my truck is stock.

Clarification

Just to clarify I always fill my truck the same way. On the day I did this high mpg trip I filled up before and after at the same chevron in temecula. I initiate full flow and trigger the hold open latch. When it snaps off I wait about 10 to 15 seconds and then initiate full flow again. When it snaps off again I consider the tank full. Not sure why this mpg triggered a few bs accusations but what a ya gonna do. Who knows maybe my truck is just "special."

I wonder what my "M"PG would be if I put the rear axle on jack stands and set the cruise to 60mph and just let it go.

I think that number is more interesting than this thread =D

I just got a 97' and seeing these numbers is great. Rock on :brushteeth:

Not sure why folks are waving the BS flag at the OP. My Runner routinely gets 22-23 MPG even on snows in the winter. Mine's a 5-speed. My daily commute is about 10 miles, most of it over 45-55MPH highway (not freeway). I've managed to get 24MPG a couple times on long stretches of highway.

Sweet spot, fuel-economy-wise, is going to be about 50-60MPH with stock tires. Any faster and things start to go bad; when I go 80 in southern Utah I get about 19-20MPG, and when I drove out to Bishop on US-6 going 90 I got about 16-17MPG and was seriously worrying about whether I'd have enough gas to get between Ely and Tonopah.

I calculate my mileage every fill up. My '99 just turned 400,000 miles and I average 19-20 mpg.

Couple of days ago was my 1st highway trip with a ScangaugeII, 45 miles @ 72 mph one way, averaged 19.5 mpg. I usually get 14mpg city driving. On the way back I tried 75mph for 20 minutes and averaged 17mpg as well as 65mph for 20 minutes and got 22mpg. My truck is a 2000 LTD and has 230K miles, running 265/75/16 AT's.

Just bought a 3rd gen that had been sitting and with old gas and before I did a full tune up I got 15 mpg mixed driving...hoping it will go up since I've used all the old gas and did a full tune up

I'm on 265 Michelin LTX's on my '99 Limited and struggle to get over 15mpg in city travel. Haven't taken it on a trip to see what highway miles can be gotten but this vehicle gets barely 250 miles to the tank when my '03 Tundra 2WD on 265's with the same(?) engine can easily get 400 miles per tank.

Both have had the deckplate mod done. Both are in good tune.

Why does the 4R do so poorly? The MPG disparity is huge for the same engine.

Gearing?
ECM?
Weight?
4WD?
All the above?
