Max Power Member 381 Member For: 21y 13d Location: MENAI, NSW Posted 28/05/07 02:17 AM Share Posted 28/05/07 02:17 AM Was driving back from Wollongong to Sydney yesterday and, as the drive is quite boring, decided to work out the best cruise speed using the cruise control between 95kph and 110kph for economy by checking the 'inst fuel' reading. As it turned out there werent enough flat bits long enough to test all speeds out properly.Was wondering if anyone has done this so I dont need to try working this out next time again.Mine is a 6 speed manual. Im sure that a 5 speed manual and the 4 and 6 speed autos would have different optimum economy speeds so I guess we need all 4 for everyone to benefit from this.

Yet to try it in the BF though...thankfully But I’d much rather waste fuel and get away from all of the other maniacs on the road as quick as possible.
