Guess I better get those weights out of the car (Christmas Present). That's going to kill my back.

This is so true. I always keep my autos as empty as possible.

PLEASE !
Where are you getting this "information"?
2-5% is absurd. Can you provide a source for this "estimate"? The number most commonly cited is approximately 0.1 mpg for every 100 extra pounds carried as extra weight in a vehicle.
My 1981 Ford Bronco has a 32 gallon tank. At roughly 8 pounds per gallon, a full tank would increase the Bronco's weight by more than 250 pounds. That would yield a 5-to-12.5% reduction in fuel economy with a full tank, based on your figures, which I can attest it did not.
To further emphasize how absurd those numbers are - do you realize how many construction vehicles (namely Ford F-150s and Chrysler/GM 1500s) carry thousands of pounds in tools and equipment as part of their work? 2000 pounds (one ton) would result in up to a 40% to 100% reduction in fuel economy based upon your numbers, which I think agree is absurd even at 40%.
Next, how much does your mileage drop when there's four people in the car? That's easily 500 to 600 pounds in added weight, which would result in a 10% to 30% reduction in fuel economy (500 pounds at 2% and 600 pounds at 5%, respectfully). Does YOUR mileage drop that much? I don't think so.
My brother has a racing trailor he tows with a F-150, that I know weighs-in at well over 2000 pounds with tools, equipment, and bikes (motocross). His mileage drops from ~15mpg to ~12mpg when towing - and I think most will agree the most significant loss is due to wind resistance, not the added rolling weight.
And a car seat a "projectile"? By law, they're required to be strapped-in when in use, and I would venture to guess that most people do not "unstrap" them when they're not being used, only to have to "re-strap" them every time they have their children in the car.
Sorry, but nothing written above passes any sort of common sense test.

Common sense. Gee, that trunk in the photo is really full!

my trunks belong on an elephant. I've got a lot to learn; I'm already not driving as smart as I know how.

You would be surprised what people have in their trunks.

I do not think many people have a hundred pounds of dead weight junk they are carrying around. They may need to cleanout their vehicles but the posts have better ways to increase mileage than this article does.

Even worse are luggage racks - sometimes they cannot be helped but when use is over - that them (cross bars) off - even if they are partly integrated.

Thanks for info! But also, aggressive acceleration and deceleration would also play a big part in 'wasting' gas. i was driving a 4 cylinder Malibu as my rental car and i put petal to the metal any chance i get without being danger to my environmental obviously... my gas consumption is more than my actual car that is 10 years older, 6 cylinder AWD A4...
