    Since the gas prices have been killing me lately and I have a good 45 minute commute...

    In your opinion, what speed is the most fuel efficient on the highway?

    .
    IMO, it's not speed as much as it's RPM's I do pretty well keeping the motor under 2K

    The better coast
    And what ever you do, don't get a bro lean. All that up hill driving will kill your mpg's.

    35-55 MPH is the butter zone, with the instant MPG is around 30 MPG-ish. I'd avoid the interstates that go faster than 65 MPH. What kills it to an average 22 on my truck is the take offs, idling and hills.

    45-50. Always coast to a stop if possible. Any time you hit the brakes you are wasting energy already expended.

    When the truck slips into final gear, that is your best mpg. 40 - 45 MPH is the best gas mileage and my little car app confirms that.

    Lowest speed in the highest gear.



    RPM is only half of it.

    Its mostly dependent on throttle position. Some guys tested this a few years ago. Least throttle position below 60mph i believe

    Get a Scan|Ultra guage and use the instant mpg reading to fnd out for you. Too much variation in truck, road and weather conditions for one answer to be totally correct for you. I will show higher mpg's at a steady 55 then at 40 (both in high gear), so you need a bit o' data to decide.

    So far I've added an Advance folding bed cover and since removed it. Gave it to my son in Maine, he has an 05 2wd. GT perfect fit seat covers. Weathertech floor mats and window vent visors. Waag center brush/grill guard. Hose clamp tailgate mod. Turned off the seat belt chime. Added Ultra-Gauge. Trailer hitch. Softopper. Replaced sun visors with slide out style. Toyota bed extender. Had Firestone Destinations and now Michelin LTX AT2 in stock size. More mods to come; Fog lights, locking storage in bed, intermittent wipers. Now looking for Radio/HU upgrade. and maybe a lift way down the road.
    Straight out highway 65 - 70 mph I'm getting around 20 mpg. Back roads with hills but long runs between "stops" I get 23 almost 24 mpg plus. That's doing about 50 or so. I found 2000 rpm seems to be sweet spot regardless of speed. Hills kill it as do stops and starts. Also watching the UltraGauge even a higher gear with a lower speed isn't ideal. An efficient engine speed seems to be the determining factor.

    I drive a manual shift 4 banger 4x4 regular cab.

    Mileage dropped recently. Winter gas I guess ???

    RPM's don't matter as much as load on the motor/throttle position
