anyway... i was curious to as what ppl in japan get as gas milage for the 20B cosmo..... after searching for a while i came up with this chart:



at the top of the chart it says (l/km) so thats self explanitory.... the x (i think) the bottom numbers would be the rpm range?

and the number 4.6 is the average of all the numbers.... the lowest is 3.2 and the highest 6.2


4 L = 1 gal
2km = 1 mile
^^ close estimate

so i took the 4.6 average and estimated it to 5km....... 5km = 2.5m (miles)..... 5km = 1L (according to the chart)..... which is converted to 1/4gal per 2.5m

2.5 x 4 (the 1/4gal) = 10........... so bassically according to the average of 4.6km/L(estimated to 5) is 10mpg


so from that.... the lowest recorded was 3.2km/L which would be 6 mpg (very close estimate)............... and the highest recorded was 6.2 which would be 12mpg (very close estimate)

FORMULA = the km/L devided by 2 then multiplied by 4

your very welcome :]

ppl.... give me some props... this woulda been pretty easy for a say 20-40 year old..... but im a sophmore in highschool...... who sucks at math...... and happens to be VERY dedicated to FDs and rotarys for a longgggg time...... and soon to have a FD with a 20B (dont hate.. im not talking out of my ***.... give me maximum 1 year)

 

4.6liters per kilometer = 1.21 gallons per .625 miles which equals 1.936 gallons per mile?
that makes no sense?

usually, the japanese and europeans measure their gas mileage in liters/100km, but even thn, those numbers would give you 51mpg or thereabouts.

 

****.. holdup.... let me chek it again..... take into concideration that i did this at around 3:40AM lol

 

And I thought this thread was useless...

No, the horizontal X-axis is dates.
First number is month.
Second number is day.
So, this looks like some kinda diary for fuel consumption.

sorry i dont read japanese lol

 

guys.... i got it.... i "consulted" a engineer (my dad lol)


FORMULA = (z) x 0.54 = MPG..... z being the km/L value

so for example 20 km/L would be 10 MPG

 

It is still off. It should be:

x L/km * (1 Gal / 3.785 L) * (1 km / 0.621 mile) = Gallon per mile

or

1 / (x L/km * 0.425) = MPG

The problem is the numbers do not make sense. If the numbers are really L/km, the average is like 0.5 MPG. It can't be that low unless these are numbers while racing or something. If the numbers were really km/L (instead of L/km), they would make more sense for general driving. The numbers would be closer to what your first thread had shown (about 10.8 MPG for an average). So we don't really know the numbers without knowing more about that chart.

 

it is l/KM... sorry............ in my first post in the chart u can see it is l/KM


and the chart was rocored through heavy japan freeway traffic btw

 

aright **** it.... i give up on math

 

a neat trick - try to type this into google :

"4.6 kilometers per liter in miles per gallon"

It will do the conversion for you.

 

Yeah, I know what the chart says. The numbers just don't make any sense. As Steel said, in Japan and Europe, they usually measure fuel use in L per 100km. However, the numbers on the graph don't make sense that way either. Maybe you can put a link to the site where you found the chart. Maybe someone on here can read Japanese and figure out what is going on.

You did make a good attempt at the formula. Here are a couple rules that will help in the future.

1. Check to make sure the units are correct. Often things can get mixed up when converting one thing to another.

2. Check the answer to see if it makes sense. In this case, we know the answer shouldn't be real low like 0.5 MPG and we also know it shouldn't be real high like 50 MPG. If you have an idea of what the final answer should be, it will help to tell you if you made a mistake or not.

Don't give up on math. I know it can be hard at times. The more you use it, the easier it will become.
