Engine Oil Grade — Proton Models Malaysia
Proton Saga/Persona use 10W-30 or 5W-30 SN. For X50/X70/X90 with the Geely 1.5T TGDI, only 0W-20 or 5W-30 SP/SN fully synthetic is acceptable — the turbo demands low-viscosity synthetic oil. Mixing mineral and synthetic is not recommended. Change every 5,000 km; never stretch to 10,000 km in Malaysia's climate. Always check the API rating: SP is the latest standard and backward-compatible with SN.
