I have a couple questions based on some of the replies to the original posting: someone said (I think) that coasting in neutral does not save gas. Is that true, if so why? The rpms drop way down and there is no load on the engine. In this regard, someone suggested coasting in gear, saying that the engine used no gas. Is this possible? I mean the engine is still running. Also, someone else suhhested 89 octane. Will this have any adverse effect on engine (deposits?). Thank you.

I know that someone from a TSX forum tested different gas octains, see link below. It is a long read, but the experiment was interesting.

If the engine computer sees no throttle and the engine is above idle then it shuts the injectors off; the engine becomes a big air pump.
If you coast in nuetral then the injectors will stay on to keep the engine idling.

This can also be seen in something like a ScanGauge.
One of the hyper-miler techniques is to accelerate up to a speed and then coast down with the engine off. It's a sure fire way to surprise/piss off the people behind you!

100% true. If you're bored and want to verify this, coast down in gear and turn the key to the 'acc' position. Then back to the running position. There won't be any change. Use your brain: you lose power steering in acc, and the steering can lock if you turn it right off.

Quit going to Starbucks, and brew your own coffee. You will save waaaay more money then the couple hundred bucks a year driving your S like a granny!
I drive it how I like and get 23mpg. I drive it the same roads very easy and get 26mpg. so for the torture of driving slow, I saved a couple bucks.
Bottom line... there are easier ways to save a few bucks

So many of their techniques are soooooooo unsafe and illegal. Also I would think that most of what they do lessens the life of several components on the car.

My mileage varies between 17 to 30mpg.
Yes, 17 was the lowest I've seen!!!!!!! It was 100% city driving. I do get stuck in city traffic a lot, and the car would sit through the traffic for 20 mins to get through 5 blocks
I feel sorry for my engine.
Anyway, enough of blaming on the traffic. I also love downshiting with rev-match, and of course, I get to VTEC from time to time as well
That probably robs away from mpg as well.
But then, on the highway, I do get around 30mpg.
I generally accelerate slowly in city driving and shift too early (i.e. 3.5k?) on flat roads, maybe that has to do with my fuel-economy partly. Along with downshift and everything, I definitely am not the most fuel-efficient driver. There are also a lot of hills in the area that I live in. On average, I would say I get around 22mpg with a combination of spirited driving, city driving, highway driving, hilly driving and my shifting habits.
