I own a Patrol with a diesel six cylinder 2.8 l, non-turbo, of 1995, so it’s not really what you’re looking for. But, for this engine, anyway all I can say is that after 150.000kms, 2 trips to Morocco, 1 to Morocco, Mauritania and Senegal, and a LOT of off-road in my country (due to my job) I considered it a 100% reliable vehicle (never let me seriously down). On my last 34-day trip of 10.600kms (Portugal-Morocco-Mauritania-Senegal-Mauritania-Morocco-Portugal) the only misfortune was a 6-year old battery who died in Marrakesh !!
The performance is not very good, but personally I don’t like to drive forcing the engine to its maximum, so usually I don’t go over 100 or 110 kms/hour. The fuel consumption (with 700kg of cargo) is around these figures: road/highway/rocky piste – 12 to 14 litres/100kms (depends on your driving style); sandy piste – 18; dunes – 20.
Until now, all I can say is that Nissan Patrol has the reliability of Toyota at a price of a LR, and I hope it keeps that way.....
