Thread: New Hilux Fuel Consumption

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

I know the answer. Apparently its all the 'other' logistical parts at each end that make rail uneconomical. The train itself, loaded to the gunnels from Auckland to Wgtn will beat them hands down in a fuel economy challenge.

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.
Big thing is have power gonna use it.....power uses fuel.

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 ????????

and if you drive to conditions and slow down BEFORE the corner...the new work truck your boss buys you for fert spreading will still be on origonal brakes 8 years later too....... slow down slowly,speed up slowly...yip could well be mantra of a heavy truck driver....

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'

What exactly are you trying to acheive here? Best pulling/overtaking in top gear? Best economy?
Changing two diff ratios is gonna take many many thousands of km to pay off if it even does for fuel savings.

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 well

You will probably find peak torque is at 2200-2400 peak power will be up around 3500.

Raising the final drive ratio will be a gain in economy in light load situations like flat roads tail wind etc but a loss in economy when load goes up and more strain on everything in the driveline.
