Am looking at updating my current 2000 3.0litre Nissan with a current 4.2 or 3.0.

Can anybody help with a current summary as I intend driving the mountain trails plus some long distance towing of an 18foot caravan.
I notice the 4.2 has a diff ratio of 3.9 compared to the 3.0 with 4.3. How does this effect high speed towing & trail work

Actually contemplating an upgrade myself, however I'm looking closely at the 4.8. Why?? The extra cost of the 4.2 takes at elast 10 years to recover in fuel savings, and with petrol, you have power on tap, and a quieter engine, and less maintenance. You also get the higher diff ratio!

I think you'd find the 4.2 TD quieter than your 3.0, they are noisy buggers, go like a shower of sht but not real quiet. My surf 3.0 TD sounds like petrol it's so quiet, but I think it's all about this pre ignition garbage they put on the 3.0td patrols, the ford transits are the same. Must be somthing to do with them being powerful and efficiant, that europein technology.

I suppose it comes down to how long you wish to keep your car. For 3 years or less I would buy a 3.0. For longer term I would not go past the tried and proven motor in the 4.2. Having both towed and driven in the high country I have found the bigger motor to be better even though it may not have the power of the 3.0. You cant have everything but with a little work you get can pretty close. The new 4.2 is a lot more cramped under the bonnet than a 2000 model and comes with cruise as std. The console is slightly wider than the 2000 model also and some switches have been relocated such as the volume button on the stereo which I use to knock sometimes whilst taking the hand off the gearknob and frighten the crap out of everyone. For long distance towing I would not pass the bigger motor either diesel or petrol.

Don't forget that the current model with the lighter plastic trim in the cabin eg dash, door surrounds, centre console etc are a bit dodgy - Nissan have taken the cheap way out and painted existing darker grey stocks of trim. A mate of mine has a new GU (couple of months old with 10K on the clock) and the paint is peeling off - making the interior look like it has been genetically modified with dalmatian code.

Patrol 22, When getting my new bullbar under warranty the dealer mentioned these paint problems with the interior and said they are covered by warranty.

Hey Old Johno,

On that same path myself. Having read this forum conducting searches on Gu's have a look at some past strings on the 3.0L TDI. Not a good report.

Leave it to you mate,

Hi Johno, Dont forget when you trade or sell privately, you will always get the extra money back with the big diesel, every cent, also you can sell privately very quickly. The petrol, well could be some time to sell privately and at a big loss.. The 4,2 is chaep at the end of the day. Regards Michael

P.S. And 11 litres per 100 ks with the 4.2 not 20 !!!

You're right about getting having a slightly higher 2nd hand value, but you have to consider the cost of having more money tied up in the car in the first place! From the Patrol list, mileage consensus for the two vehicles is 17l/100 for the 4.8 (man) and 14l/100 for the 4.2. If you drive 15000k per year, you'll spend less than $10 per week extra on petrol.

At the end of the day, you can toss numbers around to suit any argument you wish (and to get the wife to agree!) ... so as always, it comes back to what suits each best!!

Its fun discussing it though!

Gotta agree with Andrew on the economy. My 2000 model 4.2 has a permanent roof rack and lotsa gear, weighs 3050kg before I load it up for a trip. I get around 15l/100klm average since new. The 3" exhaust makes it breathe better and has helped get the power at rear wheels up to 91kw. She'll do me for another 6 years or so (at least).

Andrew, 15k a year?? I do that a quarter just driving to work!
But yeah, it's all case by case ain't it.

Hi Old Johno,

I recently went thru a similair process when upgrading my old 80 series to finally a new GU 3.0TD. I tow a 1.6T van regularly with my 2003 GU 3.0TD and could not be happier. The only two things that bug me with the 3.0TD were;
1) the lack of torque at idle and
2) the poor low range gearing.

I ended up fitting a dtronic and that has made a big difference to torque, right from idle to redline. Previously, I could not idle my van up my driveway in low range. After fitting the Dtronic, it now idles up with no clutch slipping required. Worth it for this reason alone. But it now also makes towing so much better with the extra power throughout the rev range. And best of all is fuel economy, the same or slightly better but with extra power. Who says you cannot have your cake and eat it too!

While a 4.2 and standard 3.0 may be similair in power/torque, the dtronic certainly turns the tide in the 3.0's favour by a measurable margin IMHO. Given the diff ratio of the 4.2, its low range gearing is worse than the 3.0, which I find sucks compared to my old 80 series.

Anyway, just my thoughts.
