Payload MPG Question

So if the tacoma Payload is 1200lbs does that mean I can put 1000lbs in the bed and mpg should stay the same? Thx

 

Toyotas are good, but they can't violate the laws of physics yet.

More mass to move means more energy consumed.


That said, it shouldn't be a huge hit unless you've got a heavy foot and are trying to make up for the weight by giving more throttle.

 

Whats the real payload I can put before mpg takes a hit, thx

 

Ha ha, not at all... mileage declines pretty quickly with weight unless you slow down proportionally.
If you want to keep riding at 75 and then add weight, then you need to slow down or or mileages will plummet.
I averaged 16.7mpg over a 145k.
With weight i would drop to 13-14MPG.
Embrace the pain, it is easier...
Cheers

 

Technically speaking you can't add a single pound without reducing mileage, acceleration is what will take the biggest hit on mpg so if you are hauling expect the truck to accelerate a lot slower if you want close to the original gas mileage. Also going up hills will take more gas. It also depends if what you are hauling makes the truck less aerodynamic too.

 

My normal fuel mileage is between 10 and 12mpg I would guess empty it might do a little better.

Besides the weight head winds and cross winds effect mileage.

Once the load is higher then the cab mileage drops fast.

I never noticed much difference in acceleration then to me the 3.4 has more then I need to do the job

 

I have a cap and low profile lumber rack and get ~17/18 in winter and my last tank in this 85* weather got juuuust over 20. With myself theres usually about 500lbs over empty in the truck. 4cyl with the 4.30s, 31" ATs on 15s. I drive like a grandpa mostly and half-ass hypermile.

 

Nobody is going to be able to answer that with a single number. Every extra pound you add will reduce fuel economy by some minute amount. However, I'll say that with the 3.4l I normally get 17mpg in mixed driving. When I am doing a lot of hauling it drops closer to 15mpg. My area has rolling hills, but nothing crazy steep. Typical loads include full beds of mulch (~800lbs) or compost (1200-1500lbs). So assuming for simplicity's sake the reduction in mpg is linear (it won't be) you could estimate that each 600lbs is a reduction of 1mpg.

 

This is like a 'what's the meaning of life' question, there's no one answer and yet the answer is obvious. Any weight you add to the truck will affect your mpgs. How much until it becomes noticeable depends on too many variables.

Gun to my head answer, couple hundred pounds maybe. Wouldnt be a bad hit but probably noticeable over a long drive.
