Give the devil his due, he is correct on 1/4 weight reduction.

First tank mileage came in at 37 mpg. From what I can find, stock 1.5 L automatic civic hatch got around 27 combined. I did a bit more highway than city on this tank, but was also in hilly/mountain terrain. Or at least what we call mountains here in the eastern US!

Effect of weight on a hypermiler:


Stopping more often will probably cost more fuel than you might theoretically save.

My best commute is 50MPG city in a 2+ ton van. It's not about weight.

Why not get rid of your fuel tank all together, and just install a 5 gallon fuel canister in the trunk; or a milk jug or something?

If you go really small, like with a milk jug, you could temporarily put it on the dash.

Graduate the cannister if transparent, then you can see PRECISELY how much fuel you are using.

If you're going with a small, graduated container...

May I suggest strapping one of those "rolling IV bag holder" stands to the vehicle and hanging a graduated container (with cover! IV-type bag for bonus points!) from it, with clear fuel line running down to the fuel pump? If you're going to do a precise fuel usage study, make the car look like a patient. Especially if you are driving slow, or doing pulse and glide - behaviors that make it look like the car is "sick" to the general public.
