Thread: New Hilux Fuel Consumption

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.

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)
