Thread: New Hilux Fuel Consumption

Originally Posted by stagstalker

After 9 months of waiting we finally got our new hilux a week and a half ago. Really loving everything about the vehicle so far except one thing, at 1000km on the clock she is drinking 13L per 100km with no load and doing mostly open driving with some short town transits. Automatic transmission.

As seen in the photo it has a bit of extra weight: Bullbar, winch, snorkel, under vehicle protection, steel side steps, canopy, old man emu suspension upgrade/lift, maxxis razr AT811 265x70r17 tyres (40 PSI front, 38 PSI rear), etc.

Based on the mods above I knew it would drink more then normal but when the specs say 7L highway, 9.4L city and a combined average of 7.9L, I thought it was reasonable to expect something along the lines of 11L per 100 for my setup. I get those figures are almost always ambitious but my Holden ran at 9.5L with M/T tyres in the same size and a canopy and snorkel on it..

So there lies my question to any other newer model hilux users, how is your consumption and did it improve much as it ticked up some km and broke in?

I was told when i brought a new vehicle that it won't settle down and free up till around 20,000km and then fuel economy should improve.

I fully understand that it will be a chunk more due to the mods but I really can’t rationalise it being that much. I know of a few other trucks with mates very similar with bullbars winches snorkels and big muds etc that don’t run this thirsty. Talking to my mate today who has a lifted amarok with winch, bullbar, snorkel, 33” big mud terrain tyres and when I told him what I was getting his jaw dropped as he’s on 10.2L… It’s early days and maybe it needs to be really run in and get some hard working km on the clock. 11 - 12 I can accept as an increase over the stated 7.9 in specifications but shit 13.. should have just bought a landcruiser hahah

Or better still a Ranger

I’ll let you know what my 4.5 ltr landcruiser figures are tomorrow.

The GPS on my work Hilux has the speedo out by 10km so that would push things out as far as consumption is concerned. Either way >12+/L isn’t flash I’d suggest regardless of a winch etc.

Biggest mistake you’re making @stagstalker is comparing other makes to yours. That’s a complete non-starter. Totally different engines in many respects.

Also a snorkel is meant to increase fuel efficiency.

A snorkel is designed to keep water out of your engine when you are wading in deep water. As a bonus, in dusty conditions at reasonable speed, they will reduce the dust intake. They are restrictive to air flow and if added to a stock engine with no other mods to counter their restrictive nature, will pull back horsepower and reduce economy.

For sure. Another good mate has a 2019 hilux built practically identical to mine but with BP-51 suspension instead. Last we spoke his was 10 point something but I need to follow up with him again to see if that’s still accurate. I think he had a tune done though to be fair. But yea hence why Im wondering if maybe it does need to be looked at or just get some more km on the clock.

Curiosity got the better of me, went upstairs and checked what my 4.5 ltr V8 drinks and it’s all bad news for you Hilux drivers.
An economical 13.8 Litres per 100km and that’s in shitty Auckland traffic with the boot up it when given a chance.

Mate just sent me a photo. As mentioned his is practically identical to mine and it’s on 10.9L with not the most efficient type of driving. But yeah his has been tuned too I think.

You'll need to put stock tyres back on it to see if there's a problem.

Shouldn't be too hard to do. Someone will have some.

Huge variations in tyre / fuel relationship. Rubber compounds can vary from batch to batch within the same brand.

Process of elimination will get you there.

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

Your gonna piss people off at that speed,

well them people can just "piss off" themselves...... not overly hard to pass someone who is consistantly sitting 10kmph below where you want to sit.....

Before you go digging to deep into potential issues I would get a scan gauge to give you accurate readings. I have one in my ranger and gives quite different readings to the inbuilt computer. Simple and easy to install yourself.

Mine is similar set up to yours. Steel Rims and same size and brand of tyres as yours. Bull bar but no winch or snorkel. Hard lid instead of canopy. Getting about 10.5 without the off road kms. Stock engine with no tune.

Run it in and check again I’d say

An LC200 I drive uses about 15L/100km, it has full steel ARB bar and winch, wrap around steel running boards, stock wheels but has a lift, about 100kg of kit in it and normally 4 guys.

Makes me cringe at the pump, I reckon it uses close on double what my RC Colorado uses, They do sound nice though.
