V6 hilux upgraded to the 2.8 - DISSAPOINTING

[stevebison2000]

I had the 2007 v6 hilux extracab 4x4 for several years and was thinking about upgrading
I finally placed and an order on a new 2019 sr 4x4 2.8 auto trayback extracab
I received the new vehicle end of feb

Extras steel bullbar
2 inch lift
All terrain tyres
Canvas canopy on tray.

These are the same extras I had on my v6 extracab 4x4

I have 5000 km on the new hilux and just returned from a 3000 km camping trip towing my tinny

My thoughts so far:
Car drives great, is comfortable
Very happy with it off-road
In all love the vehicle
BUT
The motor , This is where it all changes.
Fuel economy is terrible.
Packed with camping gear (300 kgs) and towing my Tinny (600kgs)
Fuel economy ranged from 15 to 18 l per 100
Towing speed range 95 to 105 km/h
This is no better than my 2007 v6 hilux was with the same mods , same canopy and towing same boat
Around town unladen in getting 12.5 l per 100 , which was very similar to my v6
And as for power , WHAT POWER ?
Overtaking road trains was a nightmare.
Max speed overtaking was 125km/h , that’s all she had in her
This is towing a 600 kgs trailer, I’d hate to be towing a 2.5t caravan with the hilux

I have contacted the dealer and he said wait until it gets 10 000 kms on it , but also admitted that there wouldn’t be
A big difference in consumption or performance.
For the record , I’m familiar with diesel utes as my work utes are all diesel tritons.

Anyone have the same issues ?

I can tell you the reason I bought a V6 2010/11 over a diesel was I do basically what you do but with 1200-2300kg on it. The V6 was adequate, the diesel no chance. The V6 would have easily seen to your requirements. I supercharged mine so I could easily and safely tow 2250kg with overtaking a breeze as my normal towing routes all have big hills and the overtaking lanes are always uphill! The downfall is the A750F’s converter though. But a replacement fixed that.
Mine is due for replacement soon, a Hilux diesel or any of this class diesel cannot do the job. So either I have to compromise on a sub-requirement power plant (which you are seeing) or buy a Ram1500 or the like. I was actually looking at a 2018 plate demo Patrol Ti yesterday, which are about the same price as a top spec Hilux. Rumour has it Nissan will be doing the Titan factory RHD next year and you have a 5.0L V8 diesel or the Patrol’s 5.6L V8 petrol engine available in those.
Doesn’t really help with yours though unfortunately! I’d sell it and buy a Ram, if you can justify and/or afford $79990 and have some more space to park it!

I don't think your economy will change much... maybe 0.5l/100km as some have reported a long time ago and maybe another engine, but not much. There is a lot of variation on fuel consumptions reported here. Be good if someone did some analysis but probably isn't enough detail in the data.

My D4D tows our 1200kg TVAN slowly but it does the job just fine. Especially with all the morons out there on our roads, I don't mind taking it easy while towing. My 200kw 600nm X5 will tow the TVAN at the speed limit up any hill I can find in SE Aus. Its only limited by the distance between service stations. I think that kind of power is way too much for your average aussie who has no professional training.

I go away with a ute full of camping gear and a trailer full of bikes and kayaks and I usually return around 11.4l/100 sitting on 110 km/h. Usually get 10.4l/100 around town and settles to 9l/100 if I do mainly freeway driving. Mine's just ticked over 27,000km and only now feels like it's run in. Before I got rid of my boat I would get 16-17l/100 and that weighed 2100kg.

Firstly I don’t tow so can’t talk to that.
I averaged basically 12L per 100 over 10,000km on my NT trip last year.
That was a lot of smooth cruising but also had a couple thousand km of bad dirt, soft sand and hard gravel.
That trip I would have been over GVM at all times.
I speak km per L so that’s equivalent to 8.5km/L
As for a Safe power boost if your interested check out the Safari ECU comes with a warranty and drivetrain warranty. Try and get that on a remap.

It’s not the most aggressive program but the fact that it won’t let you blow up the ute is a big plus. Also has a tow mode and from all reports I have got from the huts I seen running them in a 200Series they love them for the towing (yes I know V8 but still)

I have the older D4D motor in a 2013 SR5 Dual-Cab with a 3,140tonne GVM upgrade and all the non-aerodynamic parts (2" lift, steel bull bar, snorkel with mine-spec head, roof racks carrying a spare tyre and Maxtrax, etc); I just did a 4,500km trip (3,000km on gravel) fully loaded with the family and towing a 1.4tonne TVan and averaged 14.37l per 100km; so your usage seems pretty high especially given that the new motor is meant to be more efficient. One thing I would say is to look at getting a device like a Scangauge or manually work out your fuel usage if you are not already, as the standard computer is less than reliable in my experience (Not sure if this has been rectified on the new model).

n80 is using more fuel than older models - that is well documented

[Gipsy]

I guess the old adage fuel in power out comes to mind. Allowing for improvement in technology and such it is not surprising that the new 2.8 D4D uses more fuel. There is no such thing as a free lunch.

[jmag]

Ditch the DPF remap/chip seems to be the go if you want to take the chance legally and warranty wise.

[hiluxxury]

How much does that reduce fuel consumption? Does anyone have real world info?

[Bushwalker8]

Last trip in my SR 2.8 with maxed out GVM and towing 1540kg trailer averaged around 12 to 14 l/100 max over 25,000 km so the reported consumption seems high. I'm typically staying in the lower revs torque sweet spot and not gunning it unless really needed.

2018 SR. 4” intake and 3” turbo back exhaust. Airbox restrictor cut out. Remap + EGR delete.

8.5L/100 on the highway. 10 around town. Don’t even change down from 6th to overtake and I’ll see it go 100-140 in a flash. No higher than 12L/100km off road even when loaded. It’ll break traction on dry tarmac. On dirt I can barely touch the throttle without tripping up the traction control. I do anticipate I’ll need to replace the clutch early.

Granted I’m not towing but I doubt it would struggle.

[stevebison2000]

It seems from reading other posts/forums the auto uses fair bit more fuel than the manual
I’ve thought about the DPFs delete/tune and heard great results, but don’t want to affect my warranty
As the cost to repair these new diesels is huge.

Comparing it to my work ute, 2014 triton single cab 4x4 manual trayback
Ali canopy on the back roof racks and pipes on the roof ,
And 800kgs of tools/fitting permanently in it returns 10.5l per 100 religiously
And she pulls like a train

As the hilux has 50nm more and slightly bigger displacement motor was expecting more, but guess
It is what it is and hopefully it will improve with more mileage

[ggreenie]

Agreed. That seems to be a consistent report.

What’s the kw nm now?
Sounds great

Don’t know mate I haven’t had it dyno tested. I don’t care too much either.

It is great.

For reference though Just Autos claim their remap with the same mods makes about 180hp and 600Nm atw.

That package 3 power and torque curves are very similar to my supercharged V6, the diesel doesn't quite have as much torque across the rev range but close enough. The power curve is as near identical as you'd want. Not sure If you'd see a long life from the little 2.8 though pumping out that much!

Re OP, thats pretty sad. By comparison i did a 12k trip last year in my 2011 d4d which has similar mods to you but with bigger muddies. Normal i get around 10/100. On my trip towing a 2t caravan and usual speed 100-110 I averaged 16/100 in 40deg heat. 14 being the best and 18 out centrsl aust with the dredded cross winds. On the hills slowed down to its sweet spot
around 80.
With your tinny did you have it covered as the wind drag can be huge.

Yea, from reports the 3.0 does seem a lot better on fuel
That’s great economy towing a 2t van
Interesting point regarding a cover, no I did not have a cover on it
But I did just put it on a new trailer and It does sit much more horizontal, wonder if that is causing
A major drag happening In the back of the boat ? Something to investigate , thanks

I do all my driving in 5th, not drive, Automatic trans, a lot better fuel return.
Towing I use 4th or 5th depending on fuel.
I have just had fitted the Richards lockout system to lock trans in what ever gear.
Trans runs a lot cooler.
Mine is a 2016, took about 20,000 before fuel use got really better, Runs around about 12/100 on normal driving, dualcab with tray, bar and alloy box on tray.
