I made a Fuel Sonsumption System @ lfs.finalgear.com.
Below the tracks you can post your own fuel consumption for each combo.
Select the car and track and fill in your fuel consumption data.
You can find the fuel consumption in lfs by pressing F12. You see a menu called 'Pit instructions'

When you completed 1 lap the fuel consumption read appears, e.g. "0.7% per lap"
You know now how much fuel you need for completing 1 single lap. To let others know what your fuel consumption is, post your findings here.
Its quite empty still, but sure it will be filled soon.
I hope it can be usefull for you. and comments or ideas are welcome.

update
If there is a fuel report for a combo you can calculate your fuel strategy.

There are 3 basic strategies.
1/3 , 50/50 and 2/3
Start fuel, pitlap and refuel amount

If you set the Pitlap you can define your pitlap, then it calculates for that specific lap

Nice, but sth like this already exists for over half a year.

nice idea, but already done by me since more than a half year...
unfortunately you are using the same name as I did... FuelControl

FuelControl - Online
==> http://lfstools.crazyice.net/FuelControl

but maybe we can merge your data into my database...
think about it!

His is pretty nice though. It is a fairly quick and easy to read chart. If enough attention was brought to it, I am sure people would use it.

well, a redesign is easy and fast made...
so, if u only need a list...then its done in minutes

but if u use "Show consumption" you've got the same chart, but only for
one track location...

but use what u like!

but FireFox86 please us another name...

I changed the name from "Fuel Control" to "Fuel Consumption". So people won't be confused which is which.
edit: I'm wondering how active your fuelcontrol is? Is it updated on a regular basis?

Quote from FireFox86 :

Is it updated on a regular basis?

what do you mean with that?

How many reports do you get in 1 day, or in 1 week.

i don't know...
since relaunch (27. April 2006) I've got 171 posted values!

Quote from Andreas Grauel :

Tweaker is right there...
his is much easier to read etc.

now, you can also see all consumptions of all track/car combos by default:

I use CrazyICE's FuelControl. Posted a few results, and used several over the last year when calculating initial race strategies.

It's great to see what a little friendly rivalry and competition will do!
