Shell Spirax S5 DCT 10

Shell Spirax S5 DCT 10 is a high-performance, third-generation synthetic transmission fluid designed specifically for Geely/Proton wet dual-clutch transmissions (e.g., X50, X70, X90, S70). It utilizes Gas-to-Liquids (GTL) technology to offer superior wear protection, thermal stability, and smooth shifting. 

Key Features and Benefits:

• Target Application: Optimized for 7-speed wet DCT gearboxes found in Proton models.
• Technology: Uses Shell GTL base oils for excellent lubrication and oxidation stability.
• Performance: Provides better shear stability and friction performance for improved gear shifting.
• Protection: Excellent wear protection to extend component life.
• Availability: Typically sold in 1-liter bottles.
