I am about to buy a new 4x4 to replace my 89 4.2 DX Patrol. No surprise for guessing I will be getting anther Nissan. I am leaning towards a 4.2 as I have had absolutely no trouble with the last one over 13 years. It suits my driving style and I managed to get 9.7l/km out of it in a variety of conditions over all that time (including towing, town and highway as
well as offroad). As a result any economy advantage of the 3.0 does not phase me.
Problem is I have only been able to extract a very short
test drive out of a dealer not in my area as he was aware I was not buying right there and then. I have driven a 3.0 several times and it was no surprise that it spins up really nicely and pulls more revs on the road. I was surprised at what appeared to be higher revs in the GU 4.2TD over my
old truck and was hoping to use this
forum as a defacto
test drive of sorts. Although if anyone on the South Coast of NSW is willing to take me an a decent drive I am all ears.
My GQ indicates a constant 2150rpm at 100kmh. Is this the same as other vehicle get or has me tacho been wrong all this time?
What are current GU 4.2TD drivers getting when on the highway?
I fully understand the diff and gear ratio issue and the tyre size changes. However, I can still not account for my brief drive indicating that a new 4.2TD will be pulling about 2500rpm at 100kmh.
Just for interest what are the equivalent figures for a 3.0TD Nissan? Or any other vehicle you might like to advocate to me!!! This will be my third Nissan in a row over 16 years mind as the MQ SWB was just too small whan the kids came along.
Cheers
Jamie

Hi Jamie, I'm getting 900km out of 115 litres on daily freeway,GU 4.2 TDI, Goes like a train. The 3litre makes more noise and the diff ratio is lower, therefore higher final revs. I think if you are considering the 4,2 then you must be prepared to pay the extra so there is really need to consider the 3 litre. The 4.2 only electronic bit on the motor is an electronically controled EGR valve and it will probably run without it connected. It still has the old mechanical fuel pump with tolerates dirty fuel much better that the 3 litre. If you are looking for the best performing engine ,
well there isn't much in it. Pay the extra, you will get it back when you sell it and you will sell it privately, very easily, as you will find out when you sell your current vehicle.

Hi Micheal, I am near Jervis Bay and am speaking to the local Nowra dealer. They (and most others) never seem to have a 4.2 to demo. As a result I have only been for a quick drive around some
Sydney streets. My guestimate revs were based on doubling those registered at 50 and 60kmh runs on a slight downhill (so as not to annoy the brand new gearbox too much).
A short ditty from the drive! The sales girl who I drove with had no idea about 4x4s ( I know many don't male or femaile) so when the LH hub started to make an great howling noise she was overawed. A quick
check revealed that the RH hub was locked and the LH was in auto and obviously not happy in a state between in and out. The fast remedy as I did not have time fish around for the lever was to engage 4WD to put LH hub in and then disengage 4WD without reversing to keep it in. Worked
well for the
test drive but I suspect they did not fix it after we got back to the yard. If you get a white ST 4.2TD minus safety pack from McGraths Nissan in Sutherland then keep an eye on this.
regards
Jamie

One more thing Micheal, I presume, based on the local freeway speeds, that you are sitting on at least 110kmh when you say freeway? Does yous have cruise control? If so how does it go especially on the hilly sections?

Hi Jamie. That is mainly at 120 kph, I drive to Bankstown daily so have to do 120 kph or i never get there. No one holds a 4.2 in stock because they are a slow seller.. Moss Vale Nissan told me the breakup of the 3 engines, Something like 15 only petrol, 7 only 4.2 and the rest 3.0L. That is not correct but similar so not much good holding a 4.2 if you cant sell it.. i found the same problem for a
test drive. I have looked at the revs but cant give you definates . I know in 5th 130kph is 3000 rpm, with standard tyres. I'm changing my original tyres this week so i should write some figures down for comparison. If you are up this way, happy to let you
test drive, i
check the
forum most days if i have a moment.

Micheal
have negotiated a deal I am happy with but still would love a drive how do we organise it? This weekend would be good.
for interest sake $57,500 drive away for a 4.2 Manual ST with Safety Pack, Bbar, Tbar, DLights, Safari Snorkle, Cargo Barrier, Roof Bars, Mats, HLight Protectors, Bonnet Pratector and weather shields.
I guess they are still making a profit but it is a shipload off the starting price.

Jamie,
Mine is a 2000 4.2T/D with 265/75R16s instead of the 70 series they came with.
The speedo is about 7% out as checked against my GPS (when the speedo shows 100klm, the GPS shows 107k/h).
At 100k/h on the GPS I'm running a shade over 2000 rpm (say 2050).
My fuel consumption (based on odometer NOT GPS) has averaged 15.63 litres per 100klm over it's life so far (3.5 years and 125,000 klm on the clock ......actually about 133,500klm if you allow for the 7% difference in speedo reading).
Hope this helps you too. As far as I know, they haven't changed any ratios with the current TDi model.
I chose the 4.2 mainly because it HAS old technology and I might have half a chance of fixing any unexpected problems as
well as the VERY FLAT torque curve of the 4.2 which hits peak torque at around 2000rpm and holds it right up through the ("useable" in my opinion) revs to about 3,500rpm.
