klms per litre

HI philzer, Easy solved mate have a fitch fuel catalyst fitted better econ less emissions Thats what I have done.

Hi Benspoon,Answe is fit a FITCH and see what happens,remember you have nothing to risk the product is covered by a 90day money back guarantee. p/s I realy like your profile

Some folks use a system of km/litre to express fuel consumption, I guess its an old carry over from the mpg days.
It is NOT a good system IMO, the numbers you get are just too small and would require two decimal places to be reasonably accurate.

I much more prefer to use the litres per 100km figures, as in the above post, they give larger numbers for easier comparism. These also reflect the fuel usage better, IMO.

No need to convert anything here, it makes perfectly sense to me, LOL.

Hi V8troopie,
just wondering if the km/lt system is no good then using the lt/100km system how do I figure out how many litres I need to cover a 738km stretch, or how many km's I'm gonna get out of my 75lt tank?

Pezza, is it really soo difficult for you? With your first question, multiply the l/100km figure by 7.5 = (738km rounded up to 7.5x100km), therefore 15x7.5=112.5 litres.
the second question: divide 75 l by the l/100km figure, eg 75/15=5x100km or 500km.
I assumed a 15l/100km economy in both cases.

You would have to do multiplications and divisions with your l/km figures as well and get no advantage there.

Where I see the advantage with the l/100km method is: the smaller the figure the better the car economy. It is also much easier to use this method for the actual testing of the car's economy. Fill her up, drive 100km, top her up and see how much she'd used, done.

You'd have to go through several tank full's to get a reasonable accurate km/l figure since you never know *exaxtly* just how much fuel is in the tank at any time.

The economy figure is the opposite with the l/km method and you'd have to deal with 2 decimal places to get any reasonable accuracy.

Clear as mud?

G'day V8troopie,

Point taken, though I still think my system is easier, 15/100=6.66km/lt
738km divided by 6.66=110.81lt, accurate, no rounding up or down.
Second, multiply 75lt by 6.66=499.5km. simple and accurate.
You say much easier to use your system to measure a car's economy, I wish you luck in finding a servo after EXACTLY 100km of driving, using my system you top it up, drive however far you like to a servo, example 106.5km, then top up again, 106.5km divided by however many ltrs you filled up with=your km/lt.
Please do not take this in an "I know best arguing type tone" my reply is in a fun, light hearted debate. I was genuinely interested in how you use your system to calculate those fugures without first converting it to the km/lt system, now I know, so I have learnt something new for the day.
In the end, the diferences in our final calculations aren't worth losing sleep over, to travel a 738km stretch we both have nearly the same figure, add in a safety margin and neither one of us is going to run out of fuel, you say tomato, I say tomato.

Happy fuel economic traveling.

Hey Browny, THIS one isn't bad.

Good onya Blue,
