LOL, what to do without a trip odometer... When I was a kid I used to keep a piece of paper tucked into a corner of the dashboard that I used. When I got my Buick I bought a hardbacked accounting ledger book and kept that in the glove box. I wrote everything in it. Fuel, reapirs, maintenance, etc.
the way I look at it, saving gas is one thing that I can do that doesn't affect my quality of life and I can still save money. not only that, it keeps me from potentially getting speeding tickets which further saves me money.
I could sell my house and purchase a smaller one but there goes quality of life. my car is the same car and now I am getting better mileage and I am monitoring it's functions more closely so in theory, it should last longer because I will catch problems faster and take care of them before they get out of hand.
my wife is trying to save gas also, it bugs the crap out of her that I can get 26mpg in her element and she can only get 24. I was hauling wood with it at that.
I think working towards the best fuel economy will be something I carry with me throughout my life regardless of fuel prices. my first car was a geo metro so it is kind of instilled in me already. why not save some money in gas and take a fun ship cruise or something.
Be the change you wish to see in the world
