Description
Shell Spirax S5 DCT 10 is a Spirax fluid for wet dual-clutch gearboxes. It was developed for Geely 7DCT gearboxes and is based on GTL base oil, which Shell produces from natural gas.
The record lists no other ratings or car-maker approvals: its use is confined to Geely 7DCT transmissions.
Typical figures: 6.3 mm²/s at 100 °C and 27.6 mm²/s at 40 °C, viscosity index 180, pour point -51 °C, Brookfield viscosity 5,400 mPa·s at -40 °C, flash point 200 °C, density 829 kg/m³.
Application
Geely wet dual-clutch gearboxes where the manufacturer requires a Geely 7DCT fluid.
Worth knowing
The data sheet of this fluid words its only entry as “Approved for Geely 7DCT Transmissions”, that is, as an approval for Geely gearboxes, not as a statement of compliance. This sets it apart from Spirax S5 DCT X, whose VW, BMW, Ford and MB codes are all recorded only as compliance with requirements. The data sheet calls DCT 10 a third-generation fluid that Shell developed for Geely dual-clutch gearboxes. The article on checking an oil approval explains how to tell an approval from a statement of compliance and where to verify one.
The neighbouring Spirax S5 DCT 11 also holds a single approval, but for Great Wall Motors transmissions, and it is noticeably thinner: 4.15 mm²/s at 100 °C against 6.3 for DCT 10. The records of these two fluids share no code, so similar names are no reason to treat them as interchangeable.
