new model patrol

>> You are not going to save any significant money , so why not do it right first time

he is Robin, he doesnt want a thristy heap... Still havent seen anything beat that 54/100 that 4wd mthly got...

1 vote for the 3.0l I see.

Diesel... diesel..
See even ebay has rebuild kits now for the grenade! LMAO.. thats low.

I see the advantages of diesel in three ways:
1) your motor will generally last longer before attention is required
2) better economy (even though the cost is a little higher). I carried two rather than 4 gerry cans (rather than 2 carried by my fellow forby petrol driver)
3) it makes your forby sound like it should be offroad ....just love the noise (yeah I know this is a fickle point that can be argued either way)
How much more powerful is the forby with the chip? Better acceleration?
Is it worth the $1000-1500?

Huggy - I think even Bruce would agree with me that 3lt diesel is not going to last as long as petrol Patrols.

Economy doesn't translate into real economy with a new car in first few years of its life because fuel cost is under 20% of total ownership cost. And if really want economy, gas is almost always cheaper anyway.

As for noise - I prefer to hear the wildlife not the "Ticky Ticky" sound of the diesel as my wife calls it.

The chips are significantly better and can take 1 sec off the 0-100kmh time such that the auto can keep up with the much more torquey manual version of the 3lt diesel.

Robin Miller

Robin - now I am confused. I was under the impression that as a general rule of thumb a diesel motor will last twice as long as a petrol motor. Have I got this around the wrong way? Is it possible to generalise with such a broad topic....or perhaps was it the salesman who told me that diesel was better than petrol. Would be interested in your comments.

Hi Huggy

Have to be brief as gearing up for another dash into the bush.

There are lots of misconceptions in 4wd field and many are feed by
general dumbing down of specs and more interest by buyers in multiple seat
memories than performance.

Typical case is that "diesels have more torque" when all the customer has to
do is turn over the brochure to see the figures.

It is a big field but following generalization is worth while.

The main game in engine life is determined by how much it does
over how big it is. This makes it hard for a 3lt to last as long as a
4800 pulling the same weight.

Indicators of engine wear are the Engine Life Factor (ELF) and the
Brake Mean Effective Pressure (BMEP)

ELF = RPM X Compression ratio
BMEP = Power / (size X RPM)

BMEP is more appropriate for lower reving/output engines like Patrols.

Relative figures for 4800 ,4.2TDI and 3LT GU's are

4800 = 8 4.2TDI = 7.7 3LT= 10.7

I.E. The 3lt has much higher internal pressures than the others.

This makes it a lot harder to keep temperatures in the cylinder
walls and bearings under control.

The engine pressures resulting from combustion, transfer the
power thru the crankshaft via the main bearings, and heat is
dissipated into cylinder walls and oil etc.

Don't take the above to mean I wouldn't have a 3lt , in fact I think they are great cars , the fact that engine life is shorter than other patrols doesn't mean they cannot give great service for several years.
You just need to work towards an honest apprasil of the products offered and get what most fits your requirement.

Robin Miller

Huggy ,
The theory that diesels last twice as long applied thirty years age when the diesels where truck motors(4.2td still is) But with modern high output diesels they tend to go bang before wearing out.Modern petrols by contrast often do 300,000 to 500,000 before overhaul. Fuel injection has helped a lot, no more raw fuel runing down the cylinder walls and less dilutionof the sump. Hope this helps
Cheers Pete

Never seen a 3.0l overheat. It's always the 3.0l waiting for the 4.2's to cool down. Mine and others temp guages don't move and we all have the aircon etc.

Leroy

Id have to agree with Robin here, just bought a new 4.8 GU, cant beat the power it produces and the sacrifice in petrol is worth it IMO.....My 2cents worth

Cheers

Hey Truckster, I took a Freightliner Argosy B-Double (500hp Detroit) from Hobart to Burnie and back the other week, 66 tonnes going up and 59 coming back, averaged 54.4 l/100 k's for the trip :-o Who needs a petrol Patrol ??? ;-)

Thats great mate!!!!!! how do you reckon that would go on the Madigans line??????

>> I was under the impression that as a general rule of thumb a diesel motor will last twice as long as a petrol motor. Have I got this around the wrong way?

Noipe you dont, your correct.

Madigan line - I think thats where Stan went last yr with 19 petrol jerry cans in the Playdo.... Not sure.

PG... I'll come for the run next time :)

180 litres main/sub and an extra 380 litres????? Where would you fit 19 jerries anyway?

ooops.... just saw his rig profile....19 jerries!

lol... its a real eye opener aint it!

6 of the jerrys were to combat the weight of the others.

Hi Phil,
What is "eastern summer time" ?

Cheers
Pezza

Daylight savings time on the east coast of australia except for Qld.

Do you know why Qld never had Daylight savings while old Jo was the premier ?

Becaus he thought the sun shined out of his arse and he wasn't getting up an hour earlier for anyone....lol.

Cheers ... Taz

OOOOhhhhh, right, well why didn't you say you meant 'daylight silly time' .

Who in their right mind changes their clock half way through the year and then changes them back again for no other reason than not being able to get themselves out of bed an hour earlier without doing so. CUUUUCKOOOO !! :-)))
