Both 11s and 202 are synthetic fluids with slightly different viscosity ratings.
The 11s is better in extreme cold flow conditions and 202 is better in the hottest sheer conditions.
Depends on manufacturer lubrication clearences and normal operating tempreture of the fluid. Size of oil coolers, piping, oil capacity, etc all change the warm up time and normal operating tempreture of the oil
Hyundai has chosen 202 to meet its hydraulic requirements, and their engineers are generally smarter than us as they have more information than we do to compare.
From what i have heard 11s is being phased out and 202 is its replacement as BMW'S now spec both fluids and states that 202 van be used as a replacement for 11s
