saving gas?

[bucketthefrog]

Hey guys! I found this article that gives us information of saving gas… I haven’t done any of the techniques yet… im going to try it out on a new tank… what do you think of the tips?

Howcome the V-Power over there is 100 octane and it's only 98 here in Ireland. Interesting though, I drive both with the windows down and when they're up with the aircon on, fuel hog.

Most of it is obvious stuff. Baiscally, the further the throttle is pressed / the higher the engine revs, the more fuel is being used. Hence, lowest throttle position and highest gear whilst still achieving what you want is the best way.
Some of the stuff I don't agree with. E.g. It requires more electrical power to pump fuel from a 1/4 full tank than from a full one - Not unless you have a massive vacuum problem I would have thought. My understanding of that one is that you have more air in the tank and hence more evaporation, though the weight is also a concern on the other side.
Coasting up and down hills works (obviously). The comment about wearing brakes less if you're in neutral is complete cobblers.

Just drive gently, anticipate early to avoid braking and keep electrical/aircon to a minimum. Just by keeping a sensible distance and using the space to coast rather than braking, I gain 4-5mpg on a journey. On this side of the pond we're used to getting better 'gas mileage' as we've been paying big prices for fuel for a long time. My best advice is bin the US built heap and get a modern European Diesel like we run!. Take the 320cdi C/E/S classes. All the space and toys you'll ever need, real sports car performance (faster than many US sports cars) and near 40mpg!

On this side, we all marvel at how Americans can get so little power out of such big engines! I've driven new US cars recently and they are still awful. 4l V6's 5.7 Hemmy's etc - put your foot down and bugger all happens. A Merc/Porsche or even a Honda with the same size engine would spin the wheels and tear off into the distance!

hmmm obvious stuff...

However keeping ur car more the 1/4 tank is intresting point i see the point, less fuel in tank the more the car has to work to get the fuel from the bottom of the fuel tank. hell i might try this theory hmm....

hmm i've been doin the 3/4-1/4 gas tank thing.. and it does kinda make sense

The fuel pump is on the bottom of the tank, it does not pump faster when the tank is full as it is gravity fed, the head that the pump sends to stays the same,the amount of fuel it can send is dependent on the throtle opening it can therefor make no difference.

In my opinion carting round the possible 50-60 extra kilo's of a full tank over an empty one will more than wipe out any theoretical gain from easier pumping from a full tank and the extra visits to the petrol station will also hit economy. Just fill it up when it's getting low.

It takes a man that earns his living from driving to come up with a sensible answer.

Why not just mount the fuel tank higher up?

That would mean that the bottom of the tank would need to be higher than the bonnet, short people would not be able to reach it, and the car could fall over, going round corners on a full tank.

The obvious thing to would be pressurise the fuel tank then. Why not make the drivers seat the fuel tank? When the driver sits in the seat it would pressurise the tank. You wouldn't need a fuel gauge either.

There must be some reason why this has not been done before, cant think why.:idea: :neutral:

LPG tanks are pressurized - and LPG costs half as much as petrol - therefore more pressure (gas compression) + less pressure (reduced expenditure) = happiness! (to the man who knows the price of everything and the value of nothing perhaps ...)

Turnipsock has got something here, the interesting bit is the the more the person weighed, more fuel would get through to compensate for the additianal load, and when you get out the engine stops.

Very fat people's cars would be breaking the land speed record.
