Thread: New Hilux Fuel Consumption

@stagstalker 2022 9.4l per 100km same canopy as yours. Running factory tyres at the moment. Mostly open road.
The snorkel is meant to help with fuel efficiency.

Manual or Auto ?

My 2016 hilux ( manual) is 9.2L/100km all terrain tyres but no bull bar ( yet )

Do the sums on how far you have to drive to see a return on the cost of a tune, assuming that you achieve the promised fuel consumption improvement.

Then… retrain your right foot to lift and coast. Drop 5km/h off your max cruising speed. Don’t carry unnecessary weight.

Look at what just happened to the fuel consumption.

Put factory spec road tyres back on and watch the consumption fall by twice what a tune will give you.

Been through all of this for many years. Have run two sets of tyres on Hilux since the early 90s. Just recently put Toyo Open Country ATs on the wife’s Highlander due to tyre damage on the previous Goodyear HT tyres from the rough metal roads. Consumption immediately increased by 1.8L/100km. You can feel the increased rolling resistance.

I’d hate to see you waste money trying to chase a small decrease in fuel consumption.

Good point, to be fair my mate was after more power rather than economy as he wasn't paying for the diesel.

You have to compare horses really
Upgrade to 150 kw comes at a price.
My 2021 hilux has pretty much all mods.
Driving normally withoit towing just under 10 l per 100 km
Towing the side by side 13 l per 100
It uses approx 2 more litres per hundred than my 2018 model

The marketing tells you the latest engine upgrade makes it 10% more efficient on fuel

Been slowly setting up the latest workwagon (and play wagon) sticking with same OA diameter and width tyre but swapping from the factory highway tyre to Falken AT3W ATs has made 0.4L/100km increase in fuel consumption.
Even with roof racks on still getting 9.4L/km average including some light towing so not bad (new shape BT50)

On a factory vehicle with correct tyre pressures, as an average of all highway conditions.

Increase weight, rolling resistance and decrease aero and the $$$$$$ will fly out of your pocket.

Interesting thing with the 2013 ranger I have - currently running 8.5L/100Km reported on the display, and it's reasonably close to what I work out on the receipts. That's .4 higher than factory and it's on aftermarket suspension with about a 2" up at the back and 1 and a bit at the front.

Ford replaced the rear springs without touching the front which resulted in a 3" lift at the back and 1" drop at the front - made the thing a widowmaker fu*ken dangerous. I stopped driving it until I fixed it it was that bad, totally fluffed the front end alignment and it was completely uncontrollable. But, interesting finding with that much of a wedge driving down the road - fuel consumption dropped by about 1.4L/100Km, I was getting 6.9L/100Km. So possibly the aerodynamic effects of how we set the ute up on aftermarket suspension has more of an effect that we would think. The snorkel does more for drag and increasong fuel consumption than anything else I suspect, especially the ones without a scoop on them and face the rear...

Are all the figures you guys quoting measured miles by the odometer and liters put in at the pump, recorded and tabulated, or are they quoted from the reading on the dash?

I wouldn't be trusting the dash readouts. I have found them to be highly inaccurate.

My 2015 4.0L V6 petrol hilux with canopy, roof rack, 270deg awning, running oversize 286 70 R17 Hankook mud tires, all in including town/highway/towing gets me 13.25L/100km on 95/98 recorded at the pump. In standard form, I was getting 11.56L/100km on 91.

My 3.5L V6 Surf (standard on AT tyres) used to go 12.36L/100km on 91, and 11.7L/100km on 95

The forward facing snorkel are designed to force clean air in.
Also a snorkel is meant to increase fuel efficiency.

Quite happy with that. Although I only drive at about 90 km/hour normally.

No that's around 12 litres per 100 by my calculation
