Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Right, I am about to blow ALL your theories out of the water guys!! Dubbo to Melbourne in a VX1 'S' on a tank of good ol' everyday 91 Unleaded and still had about 8-10 ltrs left. that's 825kms! Oh, and the boot was loaded!!! and 2 passengers!! So to all of you trying to UP your economy on 98RON etc etc, DON'T WASTE YOUR TIME OR MONEY!!! It ain't worth it, especially in a normally aspirated Ecotec. This was also done on Cruise control at the speed limit (90% 110km/h), no "granny footing" just sparing use of the brakes, no cruise control through towns and resume once on open road. I suppose if we did try Granny footing 1000+kms on the tank wouldn't be out of the question. Now, on the trip up we had an extreme head wind, never mind though, it still got to Gilgandra on 72 Litres of 91 Unleaded! that's 895kms that time! SO you see, it's not the special fuel you use that counts, it is the fuel it's tuned for that counts! Try it, you might be surprised! Go to VY as well if you'd like to read about my Clubby and how it went on the same trip.Roh said:Hi all, I get about 700-750km from a tank of 98 Octane fuel (only takes 60l but guage says empty) and was wondering if there was any way of improving the fuel economy. I know this range isn't bad but 1000k's per tank would be a lot better!! Can it be done without hurting the engine?

thats alot of money
After doing this in my VT I got water temp, volts, litres left, litres/h and other data I didn't understand. Can anyone expand on what read outs are?VX_KN079 said:Well use the hidden computer option on the trip computer to tell you EXACTLY how many litres are left.
Before you turn the key, hold down MODE and the UP arrow. Turn the key to on and then press MODE until it shows you the litres left.
