The average fuel consumption for the Ford Ranger 2.5 diesel (specifically the 2.5 TDCi 4×4, 143 Hp, 2006-2012 model) is approximately 11.2 liters per 100 km, which converts to about 21.0 mpg (US) or 25.2 mpg (UK) based on combined driving conditions[1].
Driver experiences and forum discussions suggest that the real-world fuel consumption can range between 8 to 9.5 km/l (roughly 18.8 to 22.3 mpg US), depending on factors like driving style, vehicle load, tire size, and road conditions[5]. Some users report seeing lower consumption figures (as low as 6.5 km/l, or 15.3 mpg US), while the most optimal conditions might allow up to 10.5 km/l (24.7 mpg US)[5].
Older diesel-powered Rangers (such as the 1983 model with a Perkins 2.2L engine) achieved exceptionally high fuel economy, reaching up to 41 mpg on the highway, but these models are largely different in performance and specifications from the more common 2.5 TDCi[6].
For comparison, users have noted that modifications like larger tire sizes or additional weight (e.g., toppers for the truck bed) can further lower the mpg achieved, sometimes dropping to around 14 mpg in less ideal situations[3].
