Hi Folks,
I have a Patrol ZD30 auto with 10,000 k's on the clock that I've had since new. The best fuel consumption I've achieved was 14.2ltrs per 100k driving around the outer suburbs of
Brisbane, (not in peak hour traffic), with some highway work. The worst was towing a 1000kg camper trailer where I used 16.5 ltrs per 100k.
We have just returned from a 2000k round trip towing the camper trailer (1000kg) where I averaged 15ltrs per 100k highway driving (cruising speed was usually 100kph). So far, the Nissan owners I have spoken too, reckon they are getting better towing economy than that, even when pulling 2.5 ton full height vans. My consumption when I'm not towing does not appear to change much. On the
forum I see in the discussions, people claiming figures of 900-1000k from both tanks (not towing of course). These are figures I can only dream about.
My Nissan dealer reckons my figures are acceptable for a 3.0 lt patrol.
The ADR label on the vehicle indicated 10.9lts per 100k. The only way I could achieve this would be by getting a tow.
Are my figures comparable with fellow ZD30 owners? Is it worth getting a dynotune to see if there is a problem? or do I learn to live with the sucky fuel economy?
Any advice would be appreciated.
Thanks, JJ

Hi DesC,
It's a stock standard ST and no roof racks.

I get long term average figures for
Towing Full Caravan in 4th 6.5 Kilometres/Litre or about 16 litre/100 ks.
I tow at around 90 KPH
Non Towing Highway 9.1 Kilometres/Litre or about 11 litres/100 ks
I drive at around 110 on the freeway, 100 elsewhere
Truck has done 170,000ks

Yes your economy looks about 2-3 l/100Km more than I would be getting. definitely worth getting it checked out.

JJ,
We did a NT - WA trip early last year towing our CT which would be over 1000kg loaded.
We also have a roof rack, and our average for the round trip was 13l/100km.
We averaged around 95km/hour for the whole trip, and had the air con going for the best part of the trip.
Hope this helps,
Geoff.

Hi JJ,
I average:
11.5 l/100km around town (typical freeway, stopstart stuff etc...)
11.0 l/100km in country running (100km/km flat terrain).
15.7 l/100kms when towing my van (1.6T) at 100km/hr.
This is with 33" tyres (GPS corrected speedo readings for fuel economy) and roof racks plus Dtronic fitted (do not think Dtronic has any impact on fuel economy). So yes, your fuel economy sucks and is not typical of any normal 3.0TD I know about. Definielty take back to your dealer and don't let your dealer get away with being slack about fixing the problem!!!
Cheers
Captain

JJ,
You need to make sure that you compare the figures with auto ZD30s and not manuals, the auto has the same final ratios as the TD42 while the manual ones have lower gearing...

JJ,
According to p 22 of the latest 4WD Australia, your 3.0 L auto should do 110 kph at 2600 rpm.
Is that correct?

I thought that claim was bit a bit much when I read it over the weekend. My manual ST sits on 2600rpm at 100kph not 110.
Fot the record I acheive 11.7 to 12.5 around
Brisbane with 15.5 to 16.3 when towing out 2T van. I have a DTronic fitted and am not a heavy footed driver.

Patrick,
Is that 100 kph as indicated on the speedo?

JW,
That is a speedo read. I run 265/75R/16 and have had the speedo checked by GPS to ensure accuracy.

I am no tyre expert, but maybe my 265/70/R16 tyres account for the difference.

Hi JW,
I'm not exactly sure of the rev's at 110kph but I'll
check it out in the morning on the highway. MY tyres are the standard duelers 275/65r17 and as a rule I'm not heavy on the throttle.

JJ,
I have a 3ltr manual '03 and I have never bothered checking fuel consumption till a recent run 300 kms up the Hume Freeway in Victoria. I made a point of travelling at 2500 revs. which sees the speedo reading approx 95kph ( I expect that that is more likely 90kph in reality) and for that trip with a passenger and only a moderate load I managed 9 litres for each 100 km. It is fairly quiet driving but pleasant not to rush the big machine along.
Stano.

Thanks everyone, your
feedback confirms my suspicions of a problem. It appears I'm not in the same ballpark when it comes to fuel consumption. I't time to talk to Mr Nissan. I will let you know how I go.

I was speaking to my dealer re this very issue some time back...not that
mine suffers it but he was telling me this is an indication she is being over fueled and has the potential to be 3.0tdi victim. It'll be your ECU for sure. Nissan will replace them if they think it's a threat..I have had
mine done re other issues.
You just need to find a dealer who knows the issues and that it is overfueling that makes them go BOOM.
Shop around..your problem will be solved.
I wouldn't drive to far from though until it's fixed. How old is it anyway? still under warranty I presume...they'll fix it.

Hi Andrew,
the car is only 5 months old and I can only hope there is no long term damage, as I indend to keep this vehicle for years.
