Owners are reporting varying fuel economy figures for the Prado 150 2.8L diesel (1GD-FTV) engine, ranging from 7.5L/100km to 15.5L/100km. Some consider the figures higher than expected for a modern diesel. The accuracy of the in-car trip computer is also questioned.
Possible Causes & Contributing Factors:
- Driving Style: Aggressive acceleration and deceleration increase consumption.
- City vs. Highway Driving: City driving generally results in higher fuel consumption.
- Accessories: Bull bars, winches, roof racks, lifts, dual batteries, and larger tires increase weight and aerodynamic drag.
- Towing: Towing significantly increases fuel consumption.
- Tire Size: Non-standard tire sizes can affect the accuracy of fuel consumption calculations.
- Engine Load (Manual Transmissions): Lugging the engine in too high a gear increases fuel consumption and can cause other issues.
- DPF Issues: White smoke or frequent DPF burns indicate a problem.
- ECU: Some users report that the ECU may need an update.
Solution
- Accurate Measurement: Calculate fuel consumption manually by tracking kilometers driven and liters used at each fill-up.
- Driving Style Modification: Drive smoothly, anticipate traffic, and avoid unnecessary acceleration.
- Gear Selection (Manual Transmissions): Select appropriate gears to avoid lugging the engine, especially on hills.
- DPF Check: Investigate any white smoke.
- Tyre Size Calibration: Adjust fuel consumption calculations to account for non-standard tire sizes.
