    Welcome back to the grind :D

    The national average gas price has crept up 1.2¢ since last week to $2.877 - this time last year it was only $2.252 so it's 27.8% (+62.5¢) dearer.
    Diesel is unchanged at $3.169. It's 29.7% (+72.6¢) more expensive than this time last year. Diesel is at a 10.1% premium to regular.
    E85 is up 1.8¢ to $2.432 - a year ago it was still below $2 at $1.961 so 24% dearer.

    I thought it was only 1 mpg per hundred pounds?

    Nice ride , Gord ! If I had THAT , I could probably average xx.x MPH. :)
    Today , 70 deg F , wind SE 3-6. 15.4 miles , 82.68 MPG.
    Tank is at 441.5 miles , 76.07 MPG. Tonight , Wednesday and Thursday will
    be challenging for me. I have to drive at inconvenient times to improbable
    places after work. I might "only" get around 70 MPG actual. I will do my best to
    keep this tank up. Right now it's close to my PR tank MPG , but there's a long way to go.

    Wind, uphill/downhill, traffic, my own inconsistency, etc. It's so hard to pin anything down with so many variables. I just looked it up, 6 mph tailwind then headwind.

    51.6 / 5.2 - home last night
    66.7 / 5.1 - this morning

    Tank is at 51.6 / 160 miles and right on F.

    That would make no logical sense. It's more likely to be a roughly constant number of gallons per mile per hundred pounds than a constant number of miles per gallon.

    What I posted — probably not too logical.
    The ol’ rule of thumb is 1% to 2% mpg loss for every 100 pounds of added cargo.

    / somebody should write an mpg app, so you can plug in your car’s epa city / highway and all the variables for a given trip
    // Toyota should write it— prolly sell a few more Prius

    So if you load 10,000 to 5000 pounds on a heavy truck that gets 10 mpg empty, its mpg would drop to zero?

    You're lucky your passenger tolerates your efficient driving. :D

    Sounds like Carcus has a rule-of-thumb that may well work in some limited situations and with limited vehicles upon which the rule was derived.

    Hey, if you stuck 10 tons on (might not all fit *in*) any of my past ICE vehicles, I'd probably get zero MPG as well. :D

    Well , I met her there , so all my driving was solo. But this girl HAS been a passenger before and knows what to expect.

    This would depend on the car, and where you put the weight - if you add all the weight in the very back, and the rear of the car is lowered, then there will be a lot of change to the aero drag. Also, the proportion of added weight to the total weight of the car - a lighter car would be more affected by a given added weight, vs a heavier car.
