Title: Is a V8 petrol comparable to a V8 diesel for towin

Things may be changing.

...........  In many thousands of kilometres criss-crossing Australia towing caravans of varying weights with diesel V8-engined Toyota Landcruiser 200 Series 4WDs, I’ve come to expect their fuel consumption to range from 18-21.5 litres/100km, depending on the weight of caravan, the road conditions including the terrain, the wind direction and the average travelling speed.

My recent round trip from Southern Queensland to Daintree, towing my 2.7 tonne Trakmaster with the petrol-engined Patrol Ti-L returned an average of 21.4l/100km for the first 1000km, battling traffic and interminable roadworks up the coast, constantly travelling at the posted 100/110 km/h speed limit.  Returning via the less trafficked Atherton Tableland with a strong headwind at similar speeds, consumption rose to deliver an overall trip average of 22.7l/100km.           .............

..........  Yes I agree with all these points.
My BT50 motor failed and I now tow our 2800kg slideout Bailey caravan with a Jeep Grand Cherokee Laredo 4x4 3.6lt V6 nonturbo petrol.
It averages 16 - 20 lt/100km normally 17-18 lt/100km on 91 octane ULP. The Jeep does not need weight distribution bars with its standard Jeep tow ball and rides stably and safely with its self leveling rear shockers. The 8 speed automatic gear box does a great job but does get a bit revvy up a steep hill in cruise control. Petrol stations need to be assessed for access and exit if pulling a long van.
When not towing, it is a great daily drive with plenty of performance from it's 213KW motor and quiet smooth ride.
A V8 Jeep would be nice but fuel cost and purchase price would only be ok if you have to tow upto 3500KG        ............

About 5 years ago a V8 petrol landcruiser (used) was about $15K cheaper than the same ago V8 diesel.

Main difference was, the diesel had huge kms on it, often while towing 2.5 tons.
The petrol had had much lower easier kms on it

.........  Nissan’s 5.6-litre VK56VD VVEL mill is a beautiful bit of machinery. It comes from the same engine family as the engine used in the Nissan V8 Supercar (the American-built VK56DE, which is also E10 fuel-friendly). VVEL stands for Variable Valve Event and Lift system, which allegedly helps with fuel economy and performance especially under wide-open throttle.

It’s an all-alloy 32-valve twin-cam engine that uses direct injection to get petrol to the pistons; it’s smooth, powerful and a lot of fun. There’s also the added benefit of this Patrol being quite reasonably priced considering the amount of kit it offers, and it’s a lot cheaper than its big diesel wagon rivals.


A 200 Series Land Cruiser VX diesel (its closest rival in terms of options) has a price of $99,170 – even opting for Toyota’s 4.6-litre petrol V8 only drops the price to $94,070. The eight-seater Patrol Ti you see here drives away for $78,393, and you can buy a lot of juice for that price difference.

2017 Nissan Patrol Y62 V8 badge.jpg  Maybe in this new Euro 5 environment, the case for shelling out a premium price for a diesel fourbie isn’t quite as compelling as it used to be? The thing about Cape York is that, unless you live in Cairns, it’s a big drive from anywhere. So, with a full load of camping gear in the back, we pointed the big wagon north and rolled out of Brisbane.

As a mile-eater, the Patrol is awesome; it cruises effortlessly on the open road and is impressively comfortable, plus having 300kW on tap made for effortless cruising and overtaking. Open road fuel average to Cairns was a respectable 12.5L/100km.

Cairns proved to be the last time the Patrol was going to see PULP for more than a week, so with the 140-litre tank full to the brim, we pointed it over the Great Dividing Range and beyond to the Peninsula Development Road. Many bemoan the drive to the Cape isn’t the adventure it used to be, which is easy to say unless you have to live there.     ..........

...........  The chassis, drivetrain and suspension on Y62's are very strong beefy, similar to a LC200. Jeep's and Disco's are toys in comparison.

Fuel economy wise in Melb peak hour traffic I get 17-18l/100km whereas in the Jeep I got 11l/100km. On the highway the Patrol will use 12-13l/100km, the Jeep 8.5-9l/100km. The only time the Patrol will use lots of fuel is short trips and rapid acceleration. The journalist fails to mention this but the Patrol will do 0-100km/h in @ 6.5secs which is Golf GTi territory and when you're shifting 2.8t that quick, you'll use fuel. I don't drive like nanny either as I luv the acceleration and noise the Y62 makes. No other SUV out there goes like this unless you paid $150+K for a X5M, RR Sport, Porsche Cayman Turbo, etc.

We've got a 22" caravan which weighs 2.7+t. When I tow the van with the Patrol we get 23l/100km and with Jeep I got 18l/100km. I also drive at the speed limits (100-110km/h) unlike a lot of caravaners who drive at 90km/h and pee everyone off on the highways. People with LC200 diesels get 20-21l/100km towing vans similar to ours at similar speeds. So what's the big deal with an extra 2l/100km's? Compared to the Jeep the Patrol is super stable and doesn't get pushed around by wind and the caravan. CB, I don't know what your neighbour was doing wrong, but 25l/100km is extreme or maybe he was driving at 140-150km/h?

Yeap the suspension is soft and it may lean in corners but it weighs 2.8t empty, can carry 700kg inside and tow 3.5t - all at the same time. No SUV in AUS outside of a LC200 with a GVM upgrade or a US import can do this. Also I'm not expecting hot hatch handling as it’s an SUV, nor should anyone with a vehicle weighing this much or as capable as this. I also bet though, the Patrol handles and rides better than a dual cab ute or SUV with a GVM close to 7t.

So the Y62 is actually a very good buy, it's cheap to purchase compared to the competition, is big, has tonnes of features and goes like hell. Yes it may use a little more fuel than the turbo diesel brigade, but the $20-$30K I saved in the purchase price can go towards the extra $5-$10 of fuel I use every 100km. I’m back ahead when it comes to long term maintenance………      ..........

To be pedantic they used to use it since Nissan ended their V8 Supercars program. Additionally, it was a variant, since the VK56DE is a 5.6L and the rules state 5L engines.

Just a personal question.

Why do people aim for V8's especially in Urban areas.
Do they make the effort to give these V8's a run on the outback roads? Or do they do what the rev-heads do in Canberra and have quick 'drag races' between lights and cameras? ;D

I'd imagine that the VK series engines are an updated/improved version of the VH41DE/VH45DE V8s from the early 90s. Very sound engines. Some issues in early examples where they used a plastic timing chain tensioner, but otherwise very robust. (6 bolt mains, forged steel crank etc.)

"Overshadowed" a bit by the hot rodder's favourite  - the legendary Toyota 1UZ-FE (and to a lesser extent, it's "big brother" the 2UZ-FE which graced the engine bays of some 100 and 200 series 'Cruisers).

To summarise the OP, a diesel is what you want if you're going to be a long way from fuel. Simply because they go (a lot) further on a given amount of fuel.

But, the gap is narrowing, as petrol engines become more efficient (and there's probably more "ceiling" available in petrol engine development - and more appetite for it, given emissions legislation - than there is in diesel.

Additionally, the price for entry (and, indeed, maintenance) is considerably higher for diesel vehicles, than it is for petrol equivalents...which buys a lot of extra petrol!

Spoke with a mechanic about swapping over to a diesel - he said stick to petrol - the maintenance on new diesels is astronomical in cost, mainly due to pollution laws.  Not like the old diesels where a cap of Diesel Power in each fuel load will keep the injectors clean... lots of smokey diesels around here - they have no real idea I think.

While I take your point re: entry price and maintenance costs etc. diesel vs petrol, you are aware that the 1HD-FTE is a 6, right?

And yes, maintenance costs will be higher for the diesel. That said, if the 1HD is looked after, it will go forever. Same goes for the 2UZ, come to that. It's not for nothing that both engines are venerated as being bullet-proof reliable. In the fact, the 1HD-FTE is still regarded by many as superior in many ways to the 1VD-FTV V8 which replaced it.

Yes - V8 engines can carbon up if used only around town.
Unless you are towing you don't need one.

Thanks.
I'm more a better Driver than Mechanic although I've worked around many Mechanics. Driving Taxi while back and having to use the Jedi Mind Trick on Highway Cops who think they can make some money out of drivers they think are Indian, does bring an added dimension to driving.
Like dodging Chinese drivers in hire cars going up the wrong way of streets and roads.  ::) Tourists J-walking in front and behind you and American passengers who can't understand that in Australia 'The Worker is Right' - not the Customer. I don't need to 'grovel' for tips. In fact, I made more money trying to give passengers a 'tip' themselves - but they always argued to pay me a higher tip than I was offering them.  :-? Go figure!? :P

I can see now the value of a V8.
But it's really a waste of money for anything else.

Remember when petrol skyrocketed, they tried to offer Gas alternatives and packages until the Gas price was also jacked up to make no-one 'get ahead' with the conversion.
Heaps of big gas guzzling V8's and 4x4's were on the side of roads For Sale.

So V8's beyond 'towing' are really just a facet of the 'Self Indulgent' waste culture?

Reasons to consider a petrol over a diesel for towing.

1/ Petrols are cheaper to buy.

2/ A Petrol uses more fuel when towing. Take into consideration how often you tow. If it is for limited times, a diesel loses it's advantage even more.
If you tow sensibly a petrol does not use that much more.

3/ Diesels are much more complex engines.
If you have to add that blue stuff, that is just another cost and complexity.

4/ Diesels cost a lot more to service. More often.

5/ A diesel repair can be horrendously expensive. Every part in a diesel is dearer.

6/ Diesel mechanics are dearer.

7/ Diesels are noisier and vibrate more.

8/ Diesel is smellier.

9/ Diesels can be hard to start in the cold

10/ Diesel emissions are carcanogenic and bad for the environment.

Diesels are better for towing generally sprint
That's just where diesel engines Excel

A good old-fashioned diesel engine provided you change the oil regularly
Will give you hundreds of thousands of kilometres of trouble free motoring

The problem is that to try to make them zippy
They add turbos which are a really bad idea
Then they add exhaust gas recycling systems which are a really bad idea
Then they add catalytic converters which are a really bad idea

the beauty of a diesel engine is it's very simple design

But to try to comply with pollution laws
They have made them smaller
They recycle exhaust gases and burn them twice
Which cakes the intake manifold
With something resembling burnt on carbon in a badly design oven
And then they put a catalytic converter in
Which has to be regularly burnt to stop clogging up
And all of this affects mass air flow sensors
And all the associated computer rubbish in modern engines

If you are going to buy a diesel engine
Try to buy one with a lot of cubes
And change that oil regularly

Get a smart mechanic to disconnect as much of the anti pollution gear as possible
Lol

Then the engine will be good for 500000 km

I can't stress enough how important it is to change that oil and filter
Probably twice as often as the service interval says
Change that fuel filter so the injectors are always clean
Change that air filter so the air is always clean

And then you will have a car you can keep for 20 years

Diesels without turbos have 2/5 of bugger all power

Post by aquascoot on Nov 5th, 2020 at 10:26am
They all put turbos on them nowadays

But with the anti pollution regulations
You are feeding dirty half burnt fuel back through the turbo and into the engine

So yes you get more power
But it is at the cost of longevity

And a set of diesel injectors might set you back 2 grand

Having the head decarbonated might set you back 2 grand

Replacing the catalytic converter might set you back 2 grand

Having the engine died at 250k
Rather than 500k

Means you are having the effective life of that engine

I'm more than happy to spend a little bit more on fuel
To save thousands on servicing costs
And tens of thousands on premature replacement

And if your mainly doing touring
The turbo only comes in to play
When you are tooling around in the city

They all put turbos on them nowadays

But with the anti pollution regulations
You are feeding dirty half burnt fuel back through the turbo and into the engine

So yes you get more power
But it is at the cost of longevity

And a set of diesel injectors might set you back 2 grand

Having the head decarbonated might set you back 2 grand

Replacing the catalytic converter might set you back 2 grand

Having the engine died at 250k
Rather than 500k

Means you are having the effective life of that engine

I'm more than happy to spend a little bit more on fuel
To save thousands on servicing costs
And tens of thousands on premature replacement

And if your mainly doing touring
The turbo only comes in to play
When you are tooling around in the city




Exhaust gases through a turbo don't enter combustion.

we now enter the world of the DPF

yet another source of catastrophe for the modern turbo deisel

A blocked DPF prevents exhaust gas passing through the exhaust system at the required rate. ... Increased exhaust gas temperature and back pressure can affect the turbocharger in a number of ways, including problems with efficiencies, oil leaks, carbonisation of oil within the turbo and exhaust gas leaks from the turbo.

Indeed, if only there was an easy way to clean out your DPF.


Oh wait there is.

nah,  youre wrong bojack.

a good old landcruiser HDJ 79 R 6 cyl deisel was unbreakable to 500,000 km if you did the filter changes frequently.

with a modern 4 cylinder turbo desiel  (that is in the ranger, bt50, hilux, navarra, amarok, isuzu and triton )  ie  in nearly every modern 4 wd

you wont get 1/2 that mileage.


the CAT in a hilux needs a burn every 700 km, drive thru water after a burn abd its good night CAT (2000 bucks).

the exhaust recycling ensures the top of the engine is baked with black gunk,

old cars sprayed fuel all over the valves and fuel cleans,
to save a bit of fuel , some now spray direct into the cylinder, so there go your valves.

toyotas have an oil dilution problem.

tritons and navarras gum up.

injectors get fouled.

computer codes come on and you spend 1000's at dealers getting things fixed.

its false economy.
its great for the dealers, they make a fortune fixing crap when the warranty runs out or they scam with things like the tritons 10 year warranty  ::) ::), and then have some 18 yo with acne charging you 900 bucks to do a service  ::) ::) ::).


fuel is the least of your worries,

buy the most simple vehicle you can get without all the junk on it.

service it yourself

if it sucks a bit more gas, you will still end up way way in front.




OR

buy a new 4wd
spemnd a fortune fixing the "built in redundancies"
junk it at 180,000 km when the cost becomes overwhelming

get me to tow it to the wreckers for you in my indestructable toyota

Sprint wants a good experience touring OZ.
I'd advise a low km diesel 6 from Toyota with a good service history, preferably from western nsw or qld where it hasn't been on the beach and has mainly done highway miles.

Us farmers get them sans sales tax and with a deisel fuel rebate.

Such a car , with say 150 k still has 350 k of great motoring and sprint can service it himself.


Or he can spend more than that on an endless money pit, over engineered modern turbo deisel and suffer the indignity of breakdowns

When was the last time Toyota didn't have a turbo diesel 6 in Oz. I'd suggest its 20 years at least,

You have got to be joking.

Modern cars are DESIGNED to last just a bit longer then the warranty and they are DESIGNED to only be serviceable by dealers whose BUSINESS MODEL is based on high costs due to built in complexity.

Even the modern hilux requires a special tool and a change of a factory only washer to change a simple oil filter.

They don't want you doing it .

They suggest a 20000 service interval knowing it will die at 7 years and you have to buy a new one,

Manufacturers seal their transmissions so it is close to impossible to change the fluid and the car is junk at 7 years.

They put plastic parts in engines that they KNOW will crack after a certain number of heating/ cooling cycles and cause a failure.

They want people changing cars like they change phones.

That's why a 2006 land cruiser holds its value and a modern car does not

They certainly are one of the better vehicles at holding their price.
I think  this one is a bit optimistic. it does have low kms and has many extras.

it is certainly NOT a good buy
