Why is the fuel consumption high in my 2000 Nissan Patrol?
Asked by Bernard
The fuel consumption on my 2000 Nissan Patrol is high, what could be causing this?
Answered by CarsGuide
15 Sep 2020I assume you mean it’s higher than normal, because these were thirsty trucks to begin with. The 4.8-litre petrol six-cylinder engine could easily consume 20 litres per 100km at freeway speeds and a lot more around town or in the bush. Even the turbo-diesels were no sippers.
But a sudden jump in fuel consumption can often be traced back to either tuning or a glitch in part of the fuelling system. Make sure the car is serviced and has a clean air filter and new spark plugs (if it’s a petrol engine). You can also have the fuel-injection system checked to make sure you don’t have a stuck injector that is pouring fuel into the engine when it doesn’t need it.
If the engine is fit and healthy, you can then make sure the car doesn’t have a dragging brake or another mechanical problem that is – literally – dragging it down. Don’t ignore the other basics, either; under-inflated tyres can also cause high fuel consumption. And, have you fitted a roof rack lately? These can easily add a full litre per 100km to your overall consumption figures, just through wind-drag.
