Just home from my wee North island adventure. Did 3200km and averaged 9.49L/100km. I worked it out each time I filled up. The computer on my dash shows 9.6L/100km.
I don’t drive like an old lady either, I’ll give it some jandal when needed.

3 days......300kms each way,each day...60 R2 heifers on board.....trip times,4hrs empty 4.5--5hrs loaded fuel usage???? 392 liters 400 liters 408 liters didnt fill up when got home today...but it sure shows how consistant things really are...and also Im plurry pleased I dont pay the fuel bill.
So MD you are using about 6 times as much fuel as some of these new Hiluxes, with them weighing in at 2.3 ish T, and you weighing in with a truck and trailer and 60xR2s at about 27 T of animals....so 50 T all up???
6 x Hiluxes would weigh in at 13.8 T, so your 50 T truck and trailer is somewhere around 3 times as fuel efficient in moving weight along the road as a new Hilux. Seems about right.
Now calc it for rail ;)Quote:

hilarious really....... but it is what it is....and dickheads in cars zooming past on blind corners,getting stopped by snow,grit chucked at windscreen by said dickheads thinking they are the next Hayden Patton......
my old terrano stacks up pretty well...... surprised the heck out of me to read its as good as if not better than a new wagon.
It's just being driven appropriately , if a modern vehicle was never to be accelerated any faster than you accelerate the teranno and towed the boat up the hill at 60 instead of 120 it would be more frugal than it on fuel.Quote:

so you saw me take my family of four over the haast pass with an 7x4 trailer loaded up with camping ger and the dingy upside down on top...with a 1600CC nissan avineer station wagon a few years ago then ????????Quote:

I just remembered today that my brother has a 'full on Dyno set up' in his shed for tuning his and others race cars. If I put the Hilux on it and found out at exactly what revs the max torque is at geared the hilux to be at that point or 10% below at 100 km would that be the way to set it up ?
The mantra of a Bus driver on the other hand is 'Pull out quick to avoid children'Quote:

Just arrived back from a quick trip down to Ashburton.
Averaged 8.5l per 100km not sure if thats good or bad for a 2.8 Colorado. Diesel is nearly 20 cents a litre cheaper in chch at most places.
watching road postings..NPD seems to be only beaten by the wee McKewon sites...like one in winchester and surprisingly the one in otamatata by the benmore dam beats most pump prices by good few cents.
After best fuel economy. Hilux is at 2500 rpm at 100kmh D4D. I haven't looked up specs but I presume that this would be at max HP ? Dont even know the final drive ratio. I thought that rather than change diff heads I would change tyre sizes. In the past I had a BJ45 with a 14BT and swapped out the Gearbox & transfer box for a 5 speed out of a VX Cruiser as well as the rear axel. Was 20% overdriven and went wellQuote:

Mines bang on 2000rpm at 100kph, but it’s a 2014.Quote:

I remember the 1994 2.4L sheep shagger a mate had was bang on 3 grand @100kph. Those hair dryers and other improvements have certainly managed to drive the revs down a tad. Then again a big lazy 4.2 NA diesel turns at 1950 in an auto Safari
I'm at 105kph, same model but 2015. Doubt it's a different ratio.Quote:

9L/100 km av fuel use if driven carefully
Rear end ratio selection is not a panacea
How you use your throttle is
If that crankshaft is turning your paying
Fuel use is a balance of engine load versus time running
Yep to that, kinda sums it up. Most vehicles achieve best fuel economy in the region of 65-80km/h - going over that increases the drag effect exponentially and hits you in the arse pocket.
My patrol cruises at 100ks doing 1800rpm in O/D.But the sweet spot is about 110ks doing 2000rpm.If you are gentle on the throttle all day she will do 13-14litrs /100k.Just seems to love that 2000rpm spot.
No substitute for cubic inchesQuote:

Good video on Ronny Dahl YouTube of 18month Hilux review and real world fuel consumption with different tyres. He gets 11l with similar set up

@MSL What is the actual diameter of your tyres out of interest please ?Quote:

Yea good vid that one. After a few weeks and some more manual calculations plus resetting the calculator in the vehicle i’m sitting on about 10.8 - 11L for empty driving to and from work each day. It spikes as soon as I tow anything though even my light little trailer with quad bikeQuote:

Has done a bit of towing in that time, horse float with couple cows in it, tandem trailer taking side by sides to and from town etc and probably a quarter to a third of those Ks have been off-road on farm etc. Doesn't really have anything done to it to add much weight though, Load Master flat deck, iron man winchbar front and sideboards and running Maxxis 764 in 245/75/16 which I'm pretty sure are same size as factory. See a lot of trucks with all sorts of shit on them that seem to be all about the look, big tyres and lift kits and bars all round etc and I guarantee you most simply setup farmers truck would do a shit tonne more sketchy shit than they'll ever do, day in, day out.
Definitely, I always get a chuckle seeing the utes that drive around nice and clean with a big lift, big muds and blacked out windows and a hard lid or bunch of impractical crap on it lol.Quote:

4WD vehicles today would die of fright if they were confronted with cocky's feeding out utes of old. 750 x 16 SAT tyres with every second lug cut out or if it was really serious a set of 825 x 16 Tractor grip recaps and wheel chains all round.Quote:

I've still got a set of chains too, shall we meet ?Quote:

Perhaps a meet up on the 42 traverse as been meaning to do it for years and never got around to it?
Just down the road from me to be fair!

I'd be keen to do the 42 traverse - although I think it is currently closed? Reopens 1 November.
Did a long haul up and back down the NI over the weekend unladen less a few bags and loaded with the wife and kids. Reset the consumption reader at the start of the trip to see how it went. Not too bad considering the what it was first looking like when I got it.
Just don't look at it any more:)
