1HZ engine notes — fuel economy factors
⚙
Pump timing: Half a degree on injection pump timing makes a significant measurable difference to fuel economy. Requires a specialist — not a DIY adjustment on the 1HZ.
⚙
Terrain Tamer 5th gear (0.838:1): A 0.711:1 reduction ratio upgrade kit is available. Lowers cruise RPM by ~200 at 100 km/h and improves highway economy by an estimated 0.2–0.4 km/L on sustained runs.
⚙
RPM discipline: The 1HZ makes torque below 2,000 RPM with the turbo. Avoid lugging in 5th at low speed — change down to 4th until properly at cruising RPM.
✓
Your baseline of 7.26 km/L is consistent with a well-tuned turbocharged 1HZ at highway speeds under moderate load. Expect 5.5–6.5 km/L on Angola mixed terrain, 5.0–5.5 km/L in deep sand with disciplined 4L-3rd technique, and 4.0–4.5 km/L on rocky or technical off-road.
