Description
Shell Spirax S5 DCT 11 is a low-viscosity Spirax fluid for wet dual-clutch gearboxes, developed for Great Wall Motors DCT transmissions.
The record lists no other ratings or car-maker approvals, so the fluid is intended specifically for Great Wall Motors gearboxes.
Typical figures: 4.15 mm²/s at 100 °C and 18.26 mm²/s at 40 °C, viscosity index 133, pour point -48 °C, flash point 210 °C, density 822 kg/m³. According to the data sheet, viscosity loss after the 20-hour KRL shear test is 10 %.
Application
Great Wall Motors wet dual-clutch gearboxes where the manufacturer requires a Great Wall Motors DCT fluid.
Worth knowing
At 100 °C this is the thinnest of the three Spirax S5 fluids for wet dual-clutch gearboxes in the catalogue: 4.15 mm²/s against 6.3 for DCT 10 and 7.55 for DCT X. In the cold the picture is different. For -40 °C the data sheet gives a dynamic viscosity of 6,000 mPa·s by ASTM D2983, while for Spirax S5 DCT 10, which is thicker once warm, the same figure is 5,400 mPa·s. The viscosity index of the two fluids differs as well, 133 and 180. The article on how to read an oil data sheet explains why figures like these do not let you rank one fluid above the other.
Both data sheets mark these values as typical for current production. The result of the FZG A/8.3/90 gear test is the same for both: load stage 12. The approval in the DCT 11 data sheet is worded for Great Wall Motors transmissions, with no gearbox model given.
