3.0 CRD Fuel Consumption

I currently have a 4.8 and a 4.2 diesel but I am contemplating selling the 4.8 and getting a 3.0 from 2013 onwards

I have a question for the guys who have them, what is your fuel consumption in town and on the open road.

Does the stock standard 3.0 crd have sufficient power to cruise at 120.

Thank you in advance

Just finished my first full tank with my CRD - main tank only, not sub tank. Managed to do 500km before it approached empty (light wasn't on yet). Tank started on 31's and included a trip towing our off road camper from JHB to Bass lake lodge and back. I then chaged to 33's and did the Hennops offroad trail. The rest of the mileage was a mix of highway and short trips. Fill up gave 15.6l/100kms (6,5km/l)

Does this sound reasonable, or should I be expecting better?

I’m sure you’ll see better figures in the future. I don’t know the 3.0l at all, but that seems heavy. I never look at my first tank consumption with a new car though, that first tank is always when you’re testing it out, ie, heavy right foot a lot.

With a RTT and roof rack, 4 adults with luggage and towing a loaded 750kg (unbraked) camping trailer, also with RTT fitted, coming from Kasane back to Jhb and sticking between 110 and 120 kph on 31.6" (265/70 x 17) is tyres, I managed 12lt per 100km on my 3.0 Di.

On a trip with clients following me on a safari in Namibia, I filled up in Tsumeb, spent 3 days in Etosha National Park, and left the park through the then new Anderson Gate, I got as far as Opuwo, 810km since filling up in Tsumeb. This was also done only on the main tank, with the aux tank untouched. The guage was showing very low and the red light had been on for about 50 km. When filling up, it worked out at 10.8lt per 100km.

I was not towing, but had the RTT & the small front mounting roofrack on the vehicle, it was quite loaded, on tar I was averaging 110kph and in the park, I stuck to 40 - 50kph.

The lifetime average of the vehicle is 14.7lt per 100 (as per my www.fuelly.com log). It includes towing about 6000 km in the 25,889 km that I have had the vehicle, about 25,000km with roof rack and RTT fitted and 5 trips where i was travelling some distance in LR in thick Kalahari and Namib sand. Worst consumption was 18.1lt per 100km.

I use the vehicle only on commercial safaris and on private camping trips.

Even towing, the vehicle is most comfortable and in its powerband at between 110 and 120kph. If I approach and hit a hill at below 100kph, the vehicle struggles and I may end gearing down to 3rd eventually, but at 110 or above would leave it in 5th, except when EGTs climb over 650 degrees, when I change to 4th, only to bring EGT temperatures down.

The vehicle has a larger front mounted Cirus intercooler, a 76mm exhaust from the turbo to tailpipe, still has its EGR valve and I have had to recon the turbo at 170,000km due to turbo bearing/bush failure. To tune it properly after the recon of the turbo, I've had to fit a chip at SAC in Centurion. After the initial fitment, I took it back twice to detune the chip to keep the EGTs down. It now sits at 350 degrees in normal driving and on the odd occasion hits 650 towing and climbing hills.

The Nissan specialist (partner) at SAC in Centurion, set my Madman warning to 700 degrees, saying the ZD30 would be quite comfortable with EGTs at 750 deg. I however adjusted it back to 650 deg.

Tha fastest I have had my Patrol was 140 when overtaking and there was some oemf left, but I generally never exceed 125 indicated. (speedo and GPS withing 1 to 2 kph of each other).

I am of the opinion that the 3.0 CRD model should get better figures than my 2008 3.0 Di.

I bought a 2013 CRD in Dec 19. Stock standard. It had small issues with leaking vacuum pipes which caused boost to fall away. Quickly and easily sorted. Since then its running like a steam train me very happy. So far my avg is 8.2km/L

Thanks for the replies, and especially all the detail Malcolm!

I am not to bothered at this stage, just very used to my Isuzu 250 which was very economical.

I know what you mean about the towing Malcolm, the speed can drop off very quickly if you aren't in the power band. I think this is exacerbated by a slight flat spot mine seems to have from 2000 - 2400 RPM. This probably made me use a bit more right foot as well to keep going. I'm sure once I get the 76 mm exhaust fitted and Michael spends a bit of time with her, that it will improve.

Good to know what I should be aiming for though, will be happy if I can average 12 - 13 L/100km.
