[QUOTE="Schwepps, post: 290643, member: 3592"] I know astro :), but not everybody may look at it that way. That's why there's surprise that you can get 600km on a full tank while others get only 430++. My OBC can also show close to 600km remaining when I fill up but this drops more rapidly than the km actually travelled if I then drive more aggressively than just before filling up. Logically, km remaining must be calculated from most recent FC samples, not the long-term average, in order to give you a close forecast. So using the lit/100km stat is more accurate, especially if you reset only the journey reading before doing a specific cycle like a highway drive or a home-office commute or a Goh Tong Jaya rip. You can measure the FC down to a particular route and speed. [/QUOTE]
