[QUOTE="Traveler, post: 397124, member: 7248"] Ok, I have an idea for people who are interested in comparing FC for different fuels. How about for each club drive (starting with the Kulim drive next weekend), the club does a survey of FC for each participating car? Since everyone is travelling in a convoy and travelling at more or less the same speed, going on the same route under the same weather/road conditions, the results should be more or less comparable. You would need to collect the following data: 1. Type of fuel used; ie. Shell RON95 or Shell V-Power or Esso 95, etc.. 2. Type of car/engine: E36, 2.8L (unmodified or modified) or E90 2.0L (petrol/diesel) 3. Number of passengers/luggage (incl driver): so that we know if one particular car is extra heavy or not 4. Average speed: as measured by the OBC 5. Fuel consumed (in km/L): as measured by the OBC 6. Distance traveled. For best accuracy, measurement of #4-6 should start only once you start moving from the meeting point and end at a predetermined spot (such as start when passing the entrance toll booth, and end at the exit toll booth). Also measurement should be paused (if possible) when idling so as not to skew the data collected (this affects #4 and #5 quite a bit, especially if there is a long idle period). Then you can compare the results by grouping similar engines/fuels together and see how differences in speed (for cases where there are 2 groups, one faster than the other), engine capacity, laden weight, and fuel affect the FC.
