Is a V8 petrol comparable to a V8 diesel for towing?

[sprintcyclist]

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

........... How much fuel does it consume?
Fuel consumption is a claimed 14.4L/100km on a combined cycle. The Patrol has a 140-litre fuel tank, so the fuel-consumption figure would give you a theoretical driving range of more than 900km.

It was showing 17.5L/100km on our driver display when we drove it, but after more than 150km, including plenty of low-range 4WDing, we calculated a whopping 22.9L/100km. ................

Wow

......... 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……… ..........

A diesel will outtow a petrol engine all day long. Diesel fuel economy is better and you can reprogram the engine management computer to make a diesel pull like a freight train. Diesel engines last longer.

However, diesel costs more than petrol, the diesel engine costs more, oil changes cost more, and most diesels are turbo charged and more complex and expensive to work on.

You need more gears with a diesel due to a narrow power band.
That's why semi trucks can have 12 or more gears.

Diesels have incredible low range torque. You only need 12 or more gears for the large semi tractors. Petrol engines tend to have more horsepower and do better on the top end for racing performance, but they don't compare to diesel torque and pulling power.

Here is a video of a guy in Australia who is reprogramming ECU chips on Ford 2020 F250 diesel trucks. You can easily pull a 6-7 ton trailer with this truck and hardly know it's back there. That 10 speed transmission is a beast. It has 5 different modes for different driving conditions. Economy, Towing, Performance, Rain/Snow, and Normal.

My neighbor has a 2004 F250 with a chipped 7.3l diesel and he pulls a 35 foot(11m?) 5th wheel camping trailer through the Colorado Mountains with ease.

My thoughts on Diesal VS Petrol

Diesel as others have said is high torque and good for towing

Petrol is high power as used in motor racing engines.
