My tyres are 44mm over size from memory but i still reckon it hauls! (auto).
Under 13 around town is pretty good imo, 9 to 10 cairns to perth shouldn't be to hard, have a good trip!

i think some tyres are a lot heavier than other brands, and added unsprung weight makes a huge difference to performance. I've heard the BFG AT are a heavy tyre.

my Dmax is still getting 8.8l/100km urban only weighing around 2500kg with 20,000km. manual, 2" lift, bullbar, rear bar, sliders, toolboxes and drawers with tools/gear, roof rack with cannon and ladder. stock bridgestones.

Hey Guys,

I have a few mates that purchased the LTZ Crew Cabs. 1 of them took his factory side steps off and left them off and he said it did make a difference to his fuel economy. I was a bit sceptical about it until i did it myself. I went from about 10.1 -10.9 down to 9.5 - 10.2.

The other mate of mine replaced his factory sidesteps with the ARB Side Steps (no sliders). and he said it has made no difference. if anything 0.1-0.2 difference down.

My RG LTZ Crewcab has ARB Deluxe Bar, Bridgstone Dueller D697 265/65R17's, ARB Canopy, 2" Dobinson Lift Kit. Tub Liner. ToolBox with Recovery Gear in it & GME TX3520. Odometer is 20,500km

2013 Auto LTZ space cab with 6500km, ARB steel bar, snorkel, 275/65 r17 Maxxis 980 all terrains. Carries zero weight in the rear, only dirt bikes on Sundays.

Dead stock around town (mostly city driving) I was getting about 10. With the bulbar and snorkel average 10.3-10.5, now with new rubber it's sat on 11lph for the last 4 days or so. These are dash readings so may not be 100% accurate. I've got a lift kit going in on Friday so be interesting to see how much worse it gets. I'm not overly happy with 11lph considering I don't thrash it at all and the only weight in the back is the odd leaf from a tree I park under at work. I'll have the oil and filter changed at 7500km as 15000 is just too much in my opinion. Wonder if it'll get better? I may look at a unifilter air filter as I've had much better performance and fuel economy with one on my CBR road bike.

I have only had it on a good highway run once and that was when it was stock and I was getting low 9's.

Could just be cos it's still got low k's and still needs a bit more freeing up

Suburban driving weighing in at 2450kg with the tools in the back, my RG on the last four refills is averaging 8.4 lt/100km measured at the bowser, not the trip computer. The trip computer is telling me 7.9 but it's not correct.

On my last towing trip weighing in at 4000kgs GVM, tripping around Mansfield, Bright, etc, average at the bowser when we got back home was 10.0 lt/100km. This was doing the whole trip without using 5th gear, as I always tow in "direct" (4th). I was very surprised by the result of that trip.

I got a new LTZ Crew Cab, had 7km on the clock and for the first 3 weeks was around 10.1.

I then got a Oztech 2" lift kit, Mickey Thompson MTZ muddies, ARB steel bar and snorkel, now it reads between 10.3-10.4 on the clock (no idea at the pump). That's around city and driving to Moreton Bay region.

P.S. Azza88 - make sure you take your Collie into the dealer for the 3000km check up.....if this is not done it can void the warranty! :-)

mine is a MY13 Auto. It is averaging 13.5L/100km. Vehicle has done 76K now, always highway driving.

Car is stock, with a bulbar, no lifts or big tyres.

Took it into holden complaining about the poor fuel economy, and apparently it is within Holden's accepted range.
Their mechanic took it for a 100km drive and returned the same economy, so its not a driver related issue.
Funny how they advertise such low figures, but don't back them up.

We got our 2013 (Duramax I) Colorado with 8500km's. Previous owner was driving to/from work in city but was showing 8.5 l/100 on the fuely which seemed impressive to me. One of the first things we did was swap the old Navara rims on which had 32" AT's, this brought it to about 9. After that I fit a Fulcrum 2" lift, that brought it up to about 10-11(my calculations) during our trip to tazzy, there was very little offroad involved but the ute was loaded with camping gear.

I sold my Navara with it's original rims and reverted the Colorado to the factory ones again, since then I've watched the economy vary between 8.4 and 9.5.

I'm interested to read that others have found the fuel meter to be accurate, our's always falls short, for example; Filled up last night, she took 67 litres of fuel but the gauge says only 64l used. It seems to be consistently 3-4 litres out which also affects the calculated economy.
Colorado calculates this...
760kms @ 64l = 8.5l/100km
This is correct....

But put in the actual fill amount of 67l and compensate the speedo and you get this...
760km's - 4% (speedo 4% slow with factory tyres) = 729km's
729km/67l = 10.89 km/l
100/10.89 = 9.18l/100km

I know which one Holden prefers!
Anyway, if the ECU meters 64 litres rather than 67, I'd like to know if that affects my fuel delivery?? (and performance/economy etc)

Thanks Toad, I've been wondering if all these great economy figures where actual or off the trip comp. Mine is the my12 and it's the same, always put in more than the computer says it has used. I know my speedo is acurate cause I have checked it with several GPS's and I check the litres going into the tank. I have done 55000k's now and its pretty consistant, around 8.5 to 9.5Ks/L or 10.5 to 12.5 Lts/100. To get the quoted 8ltrs/100 I think would be near impossible out of my car.

I've only done 1100km on my 2015 Colorado LS Manual.
Average says 9.1lt/100km
That's city driving.
If I take the reading for over 500km periods it says 8.5lt/100km
I use Caltex. That being said it had a full tank of fuel when I got it two weeks ago. So only filled it once.
Checking via fill/Km it's averaging 8.59lt/100km. Though I did fill it right up. 4 clicks afte rfull.
Next fill will be the check and so forth.

They can rave all they like about autos using less fuel but from what i see here nearly every manual is upto 2-3 litres less than autos per 100.

Yep. True that.
Will be interesting as I've started to get revs up higher a lot more this second tank of fuel. So results maybe a little misleading but looks good so far.
Got half tank left. But will fill it tomorrow with added 2t oil added also to test out.
