Thread: Y62 patrol

In a similar style..

My supercharged 5L D1 on 35s would go from Adelaide to Melbourne and back to Tailem bend on its tanks (not towing).

Around Adelaide for work it was good for 350km.

That thing carried 160 litres...

It used around 9L/100km on the highway, and 15L/100km in the high country, including hours and hours and hours of 1st gear moderate/difficult and somewhat extreme offroading, involving masses of very steep climbs. So, the Y62 at an average of 13L/100km, may use around 50% more on the hwy(?).

A 4.2L petrol Y61 did exactly the same stuff and used around twice as much fuel.

So how much does the Y62 use offroad?

I dont know yet as i havent taken it offroad. The y62 uses anthing from 10-12 on the hwy. The 13.1 is actaully the average since the day i bought it. What vehicle were you in?

As for torque; the 62 makes 500nm from 1600 rpm but the big kicker is the 400hp. The HP matched to its gearing makes it pull like nothing I've ever driven. The torque gets you up and going then the HP takes over. Those horses need feeding if you want to play with them

10 to 12 on the highway is pretty damn impressive. They have obviously paid attention to aerodynamics which would help, but the engine and transmission must be doing an impressive job.

Since its a heavy duty 4wd the offroad fuel consumption is relevant, and it will be interesting to see what you get.

I was driving an auto Amarok with a recently acquired stage 1 tune, so its gone from 420nm to 520nm. No noticeable difference to economy yet. Its a lot lighter than the Y62, but aerodynamics on mine arent quite as good. Fuel consumption and performance are great everywhere; in town, on highways, on sand, but it was weird to use at worst 40L to go only 170km or so, but that just seems to go with hours of first gear steep hillclimbing, and the 4.2 Patrol petrol used around 80L to do the same.

Its weird to be comparing small capacity diesels with large capacity petrols, but diesels are so grunty these days such comparisons are fair and meaningful. No question your Y62 has more top end, and if you rev it, it will go hard, but for most people most of the time thats not necessary with a modern diesel with all of their bottom end power.

Your right it is weird to be comparing a diesel to a petrol. However being a Patrol owner thats the subject that most often comes up when being asked about my vehicle.

The other thing people tend to forget is that a good percentage of owners will chip/remap their diesel, exhaust mods etc but forget that expense when talking about fuel economy. You see the patrols naturally aspirated v8 produces massive amounts of power and torque. Most owners dont bother with performance mods as there is literally no need for more. So as a example i spent over $5000 on my defender investing in a Alive remap, alive cooler, hoses, exhaust, EGT gauge. Now 5k buys me a lot of fuel!
A 200 series owner will bag my economy but forget that his chip and exhaust package buys me a lot of fuel and still not have enough power to give the standard patrol a run for its money in a drag race or up a giant hill..
....i know who bothers racing 3 ton barges, but it's an example of peoples mind sets.

A petrol will never provide the all round economy of a diesel but a diesel will never produce the HP of a petrol. However the gap isnt as big as what it used to be and the Patrol provides great all round fun that a diesel simply can't.
Ps if the cummins 5Ltr diesel was available at the time of purchase i would have bought that but i would have never known the true enjoyment i would of had with the Petrol.

I fully chipped LC 200 diesel will get fuel economy not much different from yours,in fact in some conditions may be worse.
A mate of mine has one that is done,it absolutely flies,but he pays for it in fuel costs,and probably engine life but only keeps them for around 4 yrs max.

The guy next door with a stock dual cab LC gets around 16 to 17l/100k around town,it weighs just on 3T.Loaded with accessories.

There are many diesels around that get a lot worse fuel economy than is documented.

Wow. At least they're telling u the truth, most tell porky pies regarding fuel use.

The crazy thing is that in 95% or more of driving conditions i bet my small diesel if put in a Y62 would feel more responsive and powerful than if you put an LS2 V8 petrol in a Y62, because the diesel likely has more power below 2500rpm, and that is all the revs that are needed 95% of the time with the diesel.

High output diesels give such relaxed and responsive acceleration and hill climbing that it is understandable that these days they are often the true premium offering.

However, if the Y62 V8 spec of 560nm at 4000rpm is kinda deceiving, and it actually has 500nm at 1600rpm, it might feel similar to my diesel in a Y62 below 2000rpm, and might feel better and better after that. So a bigger diesel would be a more appropriate comparison.
