Gas goes up, Car weight goes down

So since gas is getting so high lately and I deliver in my car, I decided to get my car to loose some weight... Here is whats going on so far.

Weight of each thing is based on using both of the scales we have at home, nothing fancy so I cant say its to the oz but it should be close measurements...

10.6 lbs..... Taking out the bottom part of the back seat
23.6 lbs..... Taking out the top part of the back seat
07.4 lbs..... Taking out the piece that covers the spare tire
03.6 lbs..... Taking out the rear floor mats
02.8 lbs..... Taking out the giant jumper cables I got
26.4 lbs..... Taking out the spare tire
00.5 lbs..... Random crap sitting in car I didn't need
02.3 lbs..... Passenger side-side view mirror (Electric)
--------
77.2 lbs Total

Will update any of this if I pull more stuff

Also: Geez, nothing like gas going up a ton to make you start watching that SGII like I hawk again eh? haha

I always like to see weights posted for a weight reduction. If you don't normally carry a passenger, you can take out that seat, too. It goes back in quickly, should you need it.

Me and my girlfriend take turns with cars as far as driving around to get groceries or food so Id have to keep that one in there, would be too much work to take it out and put it back in every other day

I'm considering a quick release for the partner seat on my golf... None ever ride with me, so it's extra weight/less space.

Yeah when I had my neon and my fiero that my girlfriend never wanted to ride in but did occasionally I was thinking about using like hood clips to hold the seat in and I could quickly take them out or put them back in. If they can hold a hood down safely you could use 4 to hold a seat down eh?

Some other things you can save weight with:

Spare/tools -replace with plug kit and small air compressor
Rubber foot pads on the pedals
Fixed glass - poly-acrylic
Seats: suspension seat rebuild
Exhaust: pre-muffler/resonator if equipped
Cut the plastic behind your air dam

There's more, but some involves cutting/drilling parts

Urethane is typically lighter than rubber, for bushings, but dont go out of your way to replace ones that don't need it.

With effective anticipation of lights & stop signs (i.e. not using your brakes), weight is only a second-order MPG effect. You need a longer pulse but you get a longer glide.

Some members of this forum have reported higher MPG with increased weight, because it fits the pulse & glide cycles of their commute better.

Aerodynamics, tire rolling resistance, and engine efficiency are first-order effects.

And yet still, it's fun to see just how light you can make a car without making it structurally unsafe.
