Fuel Economy - What do you get out of a tank? (3rd gens only)

Using cruise uses more fuel. That could be one explanation.

Only thing i can think of is that the drive from Sydney to canberra is flat, good quality roads and little traffic. I just put the cruise on and steered, very boring but the car just got in a groove and i dont think it changed gear once 2.5hrs.
Also checked it agianst the fuel amount used and it was right on the money, i did notice a big difference in driving north of sydney where i saw mid 8s, alot more hills, crappy roads and heaps of traffic.
I know it seems hard to believe but i double checked everthing.

I know this is a thread where you just state fuel economy, but is your car stock or any mods!!!!. I am still shocked at those figures as the best I got as stated was 9.4 on a recent trip from Mt Barker here in SA to Melbourne.

eh?

i dont think it does. if anything it uses, well, not less. but as opposed to an unsteady foot, and fluctuating throttle openings.

Using cruise control uses more fuel than not using it. I've had this discussion on here before, not meaning to be rude, but believe it or not. Try for yourself.

yes it uses more fuel on the AWD too, and I"m surprised at how much more - almost 30% as it constantly accelerates then back off, and accelerates again to match the set speed - I think the cruise control could be tuned with better in-build intelligence. I don't use it.

yeah but it shouldnt fluctuate that much. unless you are on a very uneven/hilly road.

Thats the only time you will use less by not using cruise.....and even by not using cruise I couldnt be bother driving 1000k n saving 0.05l per 100 just from not using it... gimme cruise anyday

Whoops forgot why i came in here ....

Just drove from Emerald too Brissy, total 1024k's averaged 8.7l at average speed of 101k/hr
