Gas Mileage and Gravity

[Rockey]

Food for thought: statistically speaking travelling eastbound would yield higher mpg due to prevailing winds and weather systems that are eastbound.

Higher tire pressure, advanced timing, weight shedding, efficient engine mods all affect mpg. The component that affects it the most is the one between the steering wheel and brake.

Bah, has nothing to do with magnetic fields, changes in gravity or prevailing winds.
In most of the U.S. North just happens to be towards higher elevation.
Over a long enough trip, if you were driving in a windless tunnel at a constant speed the entire time you would see a small change.

However I don't seem to recall too many long distance tunnels.

ummm, well first off; i think they were referring to the constant magnetic field that is in the northern directions.. hence the reason your compass points north. If you're at the bottom of a mountain you're compass doesnt always point towards the top....


And sorry dude, but wind resistance is a huuuuuuuuge factor in mpg...

I saw a 1-2mpg difference driving I70 W vs. I70 E across Kansas during a spring break road trip

Kansas has a constant NW headwind

Where did that come from?

And reading is good.
"in a windless tunnel"

 

[sk1er17]

i thought the windless tunnel thing was aimed towards wind resistance not mattering in some wierd way.

its 11pm here and im tired as hell, gimme a break


but a windless cross country tunnel... hmm we might be on to something here!

 

[sk1er17]

i re-read it.. think i still got ya with the magnetic field thing though

Nope, in general the Northern U.S. is higher than the South, I didn't mean compasses point up.
Of course it's 10PM here and I got up at 5AM so read what I mean, not what I type.



One of the future advances for mag-lev trains will be vacuum tunnels.
Engineers estimate that after removing air friction current trains could hit 3-4 thousand MPH.

How does one hour New York-London trips every hour on the hour sound?

I order to get my gas milage down im finally going to get a winch. I'm going to attach the cable to a harpoon and whenever I'm on long trips I am going to harpoon the nearest tractor trailer rig and coast till he exits. Can anyone figure out a way to break free?

Anyways, most of whats said in this post is pretty far-fetched. Though, it is true the most noticable changes in mpg will deal with wind and weather. If you're traveling and have a tail wind, you'll get better milage, if you're driving into a headwind you'll get worse. Have strong crosswinds and you have to worry about gusts knocking you off the road. All part of the joys of owning a top heavy vehicle.

Magnetic fields and generally the slope of the country in general- will never measurabily change gas milage. (the country slopes downwards from both sides of the rocky mountains/continental divide)

I'm mostly bored and talking out of my ass on the thread.

So... how 'bout them gas prices? It's only 2.01 for premium here, but thats still bad for what it used to be...

I always get better gas mileage going south rather than north.


(If I go south, I hit downhill ranges that are at about a 10% downgrade, when coming back north, this makes a big difference)

 

[Sallad420]

As for the megnetic aspect of getting better gas milage. It has no bearing on MPG. Just becasue you are travling North desn't mean the North Magnetic poles is going to "pull" you north. Becasue the Suth pole "pulls" with the exact same force. So if the magnetic poles could affect MPG, the south pole would cancel out the north pole. But then again, if you were far enough North, the North would have a stronger force due to the facxt that you are closer to it.

But either way, it's just plain stupid. I'm glad most people on here are just having fun.. at least I sure hope no one is serious on here. besides the wind aspect of it.

I get better MPG with a fresh coat of wax.
Smoother finish = less resistance.
I also lean forward too.
I am sure that does nothing, but if feels like it does.

 

[AniGamor]

I just paid another 35$ for a full tank of gas, maybe I should put on a coat of wax....

OR you can lift the rear of your Ex three inches so that way you are ALWAYS going down hill.

Plus Kansas is all uphill as you go west..
Goodland is like 3600 feet ASL whereas Topeka is about 900 feet ASL
