Proton X50 Fuel Economy Malaysia
X50 1.5T city: 9–13 L/100km; highway: 6.5–8.5 L/100km. ECO mode. Maintain DCT fluid. 3-cylinder: smooth acceleration avoids turbo+DCT combined fuel penalty.
- Official: 14–17 km/L (highway); realistic KL city: 9–13 km/L
- Use RON 97 — 1.5T turbo benefits from higher octane fuel
Fuel Economy — Proton in Malaysia
Proton Saga 1.3L official fuel economy: ~6.5 L/100km. Real KL city driving: 8–10 L/100km. X50 1.5T: official 7.5 L/100km; real city: 9–12 L/100km. All Proton models use RON 95 — using RON 97 on non-turbo models provides no measurable benefit. For the 1.5T TGDI, RON 95 is the minimum; RON 97 may be beneficial under heavy load (mountain driving, full load). Key tip: 7DCT clutch adapts to driving style — smooth gradual inputs improve efficiency.
