Whatever car you get her? I'd be like "Get a job. You're going to learn about payments."

Meh, she's in college full time, only child, spoiled

I worked part time all through college and grad school.

Payments FTW.

You may want to retract that low maintenance assertion. Music majors require ongoing maintenance well past the warranty period

Isnt this the same guy who didnt want to get a car with a sunroof because the extra weight would affect mileage?

Fill tank till pump turns it off, do not top it off.
Record mileage

Drive car till gauge is exactly at 3/4 tank
Record mileage.
Fill tank back up without top off

Take how many gallons used between full and 3/4th and take that and divide it into miles driven and you get mpg. Do this for several different driving styles, and mark down the one that got you the most and how you did it.

I HIGHLY recommend you do not FILL your take with something, you will ruin not only your tank, but your pump and sock as well.

This will give you a very close estimate of MPG doing this way and nothing gets ruined


If you need to get the absolute best MPG you do not use cruise control. Instead you get car up to speed and hold you foot still, even if you are heading up and incline, do not give it any more then what you gave it on flat land, and when you come down off incline/hill, let off the gass and cruise, and it will coast back to your speed limit, and at which point when road is flat, find that spot once again and repet. Granted you may piiss other behind you when you drop a lousy 5mph up a hill, but the goal here is to get the best mpg not make friends, and why no cruise control is because it will increase fule to keep you at speed going back up, and thats bad. This is the best way to get kick ass MPG, and why I can get over 20mpg in my astro van with a fitted L98 Corvette 350 under the hood. It all comes down to learning how to do what I mentioned and everyones car will all of sudden be getting 30mpg or more, or more it was rated for doing

Her Miata?... Damn, I'd like one. Not to hijack, but how'd it hold up in rear-end with such a short ass.

And OP, just take down your odometer reading, then save your refill receipt. Change in mileage divided by gas used = ???.

Oh no he can't do that, there's too much common sense.

I say he fills up the half tank with Great Stuff. Or fill condoms with sugar or sand and push them into the tank.

My fiancee was a music major and she's about as low maintenance as it gets.

This.

The feedback will make a much bigger difference than 50 pounds of gas.

You do know those degrees are bullshit outside of music studios or teaching right? And far less then 10% of people with those degrees get a job in their field, resulting in underemployment for the rest of their lives. The university is just taking your money from you.

Unless she is really gifted, I would get an intervention set up asap.

Yeah, just drive until your tank is about half empty instead of completely so. Then note down your miles, note down how much gas it takes to refill. And that will show you how many gallons it took you to go x number of miles. Simple!

I don't want to be carrying around 50lbs worth of fuel though if I don't have to...

So you're going to carry maybe 30 lbs of stuff in your fuel tank instead?

Anyways, just do what the others said and fill it up at halfway or something. It'd be a pain to remove whatever you put in your tank if you need to go to somewhere far away or something. Plus there's a chance you'll screw up the fuel tank if you put stuff other than fuel in there.

A thing that displaces the amount of fuel in the tank should not weigh 30lbs by any means, well unless it's a 1000 gallon tank! I don't want to be carrying a bunch of fuel around that I'm not going to use since it's heavy. I want to fill up often because I fill up so rarely that it makes it difficult to see how I can improve my fuel efficiency. I'm already a hypermiler but I can't use a scan-gauge because my car is too old. Why is it so unreasonable to want to make the tank's capacity smaller w/o having to buy a smaller gas tank?

Because it's mind blowingly stupd. Don't you have a loved one you can bounce this off? Someone you'll believe when they tell you THIS IS STUPID !

Well I was inspired by people who add a bladder to their toilet to reduce the amount of water they use when they flush.

This is the correct answer.

However sames OP doesn't want to carry a bunch of excess fuel around (which is retarded.)

I suppose if he could just drain his gas tank, the grab a 5 gallon gas can and fill it up at a gas station (he just needs to find a way to get there), and put it in his now empty tank. Then he knows exactly how much is in there and its not too heavy to be considered excess... rinse in repeat until satisfied.

That to me would be easier than putting something in the tank itself ...

Most things that you could use to displace gas would have a higher density than the gas itself, so you would be carrying more weight not less.

It is a stupid idea.

[StageLeft]

Castor beans, well known in south america to not react with gasoline of octanes less than 91. You can put them in and they will fit in the nozzle but are too huge to be taken up by the fuel system. You can calculate their displacement easily and fill the tank with them. When it's time to get rid of them 93 octane or higher (even an octane booster) can be put in and they'll disolve within about a tank or so. Good luck!

I've heard sugar is a good material to reduce gas tank capacity, and it's supposedly inert in gas.

a 10 lb bag ought to do it.

I heard about that. It was at the same place that told me that sand helped clean out my oil system.

How could he do anything dangerous with a tank full of sand? Actually it keeps him off the road and us safer!


I really don't understand the point of 'reducing tank capacity' - you want to make part of the tank useless to make calculations easier? wtf?

OP should just cut the fuel line and stick it in a gallon gas can.
