Proton X90 DCT Fluid Malaysia
X90 7-speed wet DCT: fluid every 40,000 km. Larger heavier SUV = more DCT thermal stress than X50/S70. Software update before fluid change. Use only Geely/Proton-specified fluid.
- 7-speed wet DCT (Geely spec fluid only); every 40,000 km; RM 280–420
- X90 is heavier than X50 — DCT thermal load is higher; do NOT extend interval
