Gas...

So I keep hearing about how our economy sucks right now and how gas prices are messing with everyone. Hopefully gas prices will be dropping (more barrels are being mined from the countries that were deemed unstable) sometime in the future, but until then I would like to ask the wise members of MCB on tips to save gas.

Obviously one should:
Clean filters
Inflate tires to proper spec
Limit harsh stops and heavy acceleration (having a hard time with this one )
Remove unnecessary weight and articles which may cause drag
Check the gas cap for leaks

But some things I have been wondering...
*Is it better to be in a higher gear and more on the pedal, or in a lower gear and light on the pedal?
*Is it better to run from a cold start (after the oil has had a chance to circulate) or is it better to wait for a warmed up engine?
*Is it better to be accelerate up to speed and coast, or to slowly accelerate up to speed (let's say on a decent stretch of road)?
*Is it better to fill up the entire tank, or to drive with a smaller amount of fuel (weight savings of the unfilled tank vs the amount of gas you loose in the hose)?
*Anyone try the water4gas thing? You supposedly make a setup to generate some hydrogen to supplement your fuel, supposedly increases gas mileage?

I'm sure there are more questions to come, but I was wondering if anyone had a clear answer on these questions and what you guys do to save at the pump .

Thanks in advance

Tall gears, low rpm, low gas used will get you efficiency. Smooth on the gas, not hammering it will be best. Fill it up all the way because the next time you fill up it will be 5 cents more anyways, save yourself the time.

If you want to save weight throw away the back seats...and other useless things like door panels.

Even on flats you will need a certain amt of gas at a certain gear ratio to keep yourself running at 70mph so just get there and stay there. For every car there is sort of an efficiency threshold. My car can run around 80 mph and get good mpg but most cars dont have tall enough gearing to do that, so at 70 or so you will get better highway mpg. Gearing is important.

Harsh stops are fine, thats break wear and neck wear.. but heavy acceleration is the killer.

Hydrogen maker thing id bet is a gimmick. Save the money and buy more gasoline.

Buy an 80s honda or toyota..

thanks for the response

I have a 00s honda so not much complaints here, I just find myself wondering little questions like if I should step on it more in fifth or go down to forth and step on it less sometimes. I've been finding gas has been staying at a stand still/going down in my area (from 4.79 to around 4.63 in washington...the state) so it may actually be cheaper for me to go the other way and put in less hoping for a cheaper fill

There are entire websites devoted to the subject- Even competitions called "Hypermiling".
Hypermiling :: No more need to compare gas prices

They say using these tricks, you can easily get over 100 mpg!

Some of those tricks are drafting behind big tricks, and turning off the engine while going downhill..... but some are a bit safer as well ..

Not silly at all....it works....ask any race team.....slick surface equals results...

Teams are also working on dimpled belly pans....like a pattern on a golf ball...makes the air underneth bounce by instead of draging by....

Move to a boonies-city like Whitehorse and buy an enduro bike. Gets 80-ish MPG, AND you can ride trails to work!

Anyways. I've found that my '04 Civic gets the best mileage in 4th, since most of my commute is highway-ish. If I stretch it, I can run 3 weeks on a single tank.

Actually, I would love a BMW RS1200... best of all worlds.

(Right now Im trying to thin the herd a bit... 5 bikes is a BIT much)
