The Nissan Navara 4.0 V6 is known for its powerful performance but relatively high fuel consumption compared to its diesel and smaller petrol counterparts. Real-world user data from Fuelly reports an average combined fuel economy of around 17.9 miles per gallon (mpg) or approximately 13.1 liters per 100 kilometers (L/100km) for the 2006 Navara 4.0 V6[2]. For the 2007 model, the average is similar, with some users noting figures slightly below that, such as 15.8 mpg (14.9 L/100km)[3]. Australian reviews cite a government-rated combined figure of 13.6 L/100km, confirming the real-world data[8].
Owners commonly report consumption in the range of 18 L/100km for town, highway, or towing, with significantly higher figures (up to 24 L/100km) under heavy 4×4 or sand driving conditions[7]. These values highlight that driving style and environment make a noticeable impact. The V6 petrol models are consistently regarded as considerably less fuel efficient than diesel variants, which often achieve between 8.3 and 9.2 L/100km[1].
If you are considering the Nissan Navara 4.0 V6, expect combined fuel consumption typically between 13 and 18 L/100km under regular conditions, with the possibility of higher usage during demanding off-road activities or in heavy city traffic[2][3][7][8]. Regular maintenance and gentle driving can help approach the lower end of this range.
