Petrol prices, and driveing sloooooow

[kiwigeo]

Just be happy that ya car doesn't run on ottled water or Coke.

Cliff...youve hit the button!!

People who complain about paying $1.30 a litre for petrol don't bat an eyelid at paying much the same price for bottled water.

They tend not to buy 60 bottles a week thought.

High petrol prices have increased the cost of lots of things delivered by road, Bread, milk, vegies, meat....I'm wondering if the price of petrol also increases the price of petrol. It's delivered by road too ?

Most petrol tankers are diesel powered

Thats why you need to drive a v8 landcruiser

Uses a &^%&* load whatever speed you go

And the quicker we use up all the fossil fuel the faster earth can recover .

Looks like I'm a greenie after all. Now to save some trees!

People in this great country need to realise that the water is going to run out before the petrol does.

Well, we did a trip recently, about 500km return. Normally the car gets about 450-500km to a tank, but including that trip, nearly 600km.

The scary part is we were doing about 130 in both directions...

In cars with half decent fuel injection systems, it also makes sense to keep the revs low. If the brainbox decides you are wanting more go, it will dump bulk fuel into the engine, especially on those cars that have a bit more go than standard. I know with the RX-8, it's about 4,000rpm, and the fuel economy goes out the window.


Next car will be a hybrid for us thanks.

I'm getting about 5.4l per 100km out of my Hyundai Accent, having changed 3 things:

1) removed the convoluted resonator before the airfilter box, and replaced it with a straight tube from grille to filter box.
2) stick it in neutral any time the road slopes down.
3) given up washing the car. I used to believe that the air resistance bit was lowered if the car was smooth and slickly polished, but look at shark skin, whale skin, golf balls, olympic swimming costumes. They all have lumps and bumps to deliberately create a small layer of turbulence close to the surface, which is supposed to reduce resistance all over.

Cheers,
Andrew

Thank you, now I finally have an excuse.

Don't forget, you save even more fuel if the boot is full of fishing gear and the cabin full of sand ... like mine

I found what buggers my fuel economy on my Cruiser is SWMBO towing the float with two TB's and the hand brake on.
Complained when she got home that accelleration was a bit lacking, also put about 500,000k's on the floats brake linings :mad:

Well that will do it.

Best economy is when you get the thing into top gear or overdrive in its recomended speed range , touch the breaks as little as possible use cruse controle , don't carry any extra weight , or roof racks, accellerate slowly , get picked up rather than pic up









Oh and pump you tyres up to a brazillion kpa,


The trouble with life is there's no background music.

If game, tuck in behind a semi and use their drag to pull you along.

[ozwinner]

Yes.
Air resistance is a square law.
Double the speed, four times the energy required to overcome the air.
Dropping the speed does improve fuel economy.
Try riding a motor bike to check out the air resistance.

If you are doing 50 kms per hour no wind, and I go to 100kms per hour no wind.
How can the wind resitance be 400 kms per hour?

Al :confused:

[Cliff Rogers]

AIR resistance Al, not wind resistance, thar's a diff-a-nance.


The amount of power required to overcome a 100Km "wind" is 4 times greater to overcome a 50Km "wind".
