    I've read a few of you managing to get 20 mpg out of your 4.7L, what route did you take to accomplish this? I'm clocking at about 15 mpg right now.

    It is actually very easy to get 20 mpg or even more. This is how you do it:

    The short answer is keep your foot out of it. But that's sort of like living your entire life on nothing but veggies in order to eek out an extra month on the planet. The usual techniques apply. Keep your air filter clean, and your tire pressures up. Avoid big gnarly tires and lifts, use cruise control when possible. In short, don't drive it like the truck it is.

    Ive noticed that if i drive hoghway with my larger tires i get killer mileage. Larger tires, engine spins slower to go the same speed. On the contrary, in town im only getting 15 15.5 or so

    I've got the 5.7L, and I swear it gets better MPG at 76mph than 72mph. Around town there might as well be a hole in the bottom of the tank.

    Lol, au contraire mon frere. I am helping you out more than you think.

    Do the math on buying a used Lexus GS350 rwd that is in the picture (11-13k with 85000 miles)vs buying fuel, a new truck 5 years earlier. Might reconcider your position kind sir.

    This is the last truck I daily drive in my life.

    Lastly, you can buy a hell of a lot cheaper car that also gets 35+ mpg. Then you see even more savings.

    I used to get 20 on the highway, 15 city pretty regular. In the past 20k miles my truck has significantly dropped in fuel economy. Not sure what happened. Now, if I am lucky, the ebb and flow has blessed me, I get 15-16.5 highway and city is dismal.

    Check with your muffler shop to see what they say. Your exhaust system has something to do with mpg. But I seriously doubt that you will get up to 20 like you wish. I had a Flowmaster installed and I got a bump of 1 mpg. I installed the Flowmaster for the sound not the mpg. I big truck needs to sound like a big truck. lol Before I retired I drove 25 mile each way on a country road and that is what I saw. But it may not be worth the price of muffler over the cost of getting 1 mpg. This was my experience as I am not an expert.

    an extra 1 mpg is about $100 per year

    Heck, why stop there? Might as well buy a motorcycle. Cheaper to buy up front and cheaper on gas.

    Maybe for you. It is about 260.00 for me.


    Before anyone says it, if you don't think that is a big deal, PM me and I will send you my PO Box number so I can get a cashiers check from you since we all seem to like giving it away. Hell, I might have a new diesel before Christmas. Better than a Go-fund-Me page....

    No, I meant for the average driver driving 10k a year. Yeah, $260 a year starts adding up. For me, it's like $40 a year, I only drove my truck 4k this year.

    That is how I am going to be now. My Tundra isn't moving unless work needs to be done. I have filled my truck up 6 times since September 26. I'm done doing that.

    On several 400 - 500 mile trips with mostly interstate driving, I get 17 MPG or maybe a little more with my 2002 4.7 Limited. All around driving, I get an honest 15 MPG. To date, I have 200,000 miles plus on my Tundra. In the Winter with snow and stop and go driving, I get 13 MPG or less.

    I used to have a 1983 Ford E150 Club Wagon XLT with the 300 CID inline six and a 4 speed manual trans with overdrive on 4th gear. The truck weighed around 5600 pounds and it held 42 gallons of fuel in two tanks. I put over 330,000 miles on it. For the first 100,000 or so miles, it had a 3.0 rear end and I could get 20 MPG on long trips using cruse control. I pull a 2500 # bass boat and I had trouble pulling it out of the lake so I changed to a 3.5 rear end. My gas mileage dropped to 12 - 15 MPG in town and on the road. However, I could pull the boat up any ramp and acceleration was better. That old 300 CID inline six with a 1 bbl carb was rated at only 120 HP and but it developed 240 foot pounds of torque at 1800 RPM. I wish that they still made engines like that.

    With gasoline now 30 - 40 % less than at its peak a few years ago, 15 MPG is not all that bad. Plus, the 4.7 V8 runs real smooth and has good acceleration and pulling power.

    A well tuned engine, properly inflated tires and conservative driving will help you maximize MPG. I think, once you reach 55 MPH, you loose MPG the faster you go as you are pushing more air out of the way. Streamlined automobile shapes low to the ground are more efficient cutting through the air than a wide and tall pick up truck.

    My ultra gauge reads 16.4 average. I drive 30 miles one way to work every day. Mostly highway but about 5-7 miles. City driving probably 50 miles a week. Stock everything
