After reading an article on hypermiling in "Mother Jones" I decided to look at this website. After some frustration with the difficulty in finding succinct, easily-comprehended information on increasing gas mileage (yes, it's there - you just have to wade through a lot that doesn't necessarily apply to you), and after finally figuring out how to post (no instructions anywhere), here I am. I own a 1992 Civic VX and average 45 mpg, just driving the way my dad taught me and using common sense (I know very little about physics or automobile mechanics). Here's a question I didn't see the answer to while perusing the forums today. Since my car really coasts well, and since there's a long level stretch of road as I near home, where I'm usually going 50, I often put it in neutral a ways before my turnoff and coast home. My question is, "Before putting it in neutral, how much should I let it slow down? In other words, what happens to the gas I already gave it when it goes into neutral? Is it simply wasted, as when I brake?" I'm trying to balance that against the amount I slow down when I let up on the accelerator, because if I slow down too much, I can't coast clear into the garage and have to give it more gas. Please don't suggest turning it off (I know there's one of those annoying abbreviations for that), as my brakes really don't do their job then, and I'd like to survive long enough to reap the benefits of fuel economy.
