Details

Rockshox 15 wt fork oil is unknown viscosity but likely 70-80 cSt @ 40°C
Motorex Supergliss 100K is 103 cSt @ 40°C
Motorex Supergliss 68K is 67 cSt @ 40°C
Motorex Fully Synthetic 5W40 is 87 cSt @ 40°C
Motorex Polar Synthetic 0W40 is 76 cSt @ 40°C

These are lower leg bath oils and cannot be used in fork or shock dampers.  They can only be used in the lower legs of forks on the air side and on the damper side if your damper is self-contained.
These oils all require good fork seals and can be used in older forks specifying 15 wt lower leg oils if the seals are updated.
In cold conditions (below zero) Motorex Supergliss 100k gets very thick and slow the fork down.  Using Motorex Supergliss 68K or Motorex Polar 0W40 in these conditions will help restore performance.
Motorex Fully Synthetic 5W40 is a good compromise between cold and hot weather performance.
