for its higher MOFT, thicker base oil stocks and probably better shear-stability than RL.
Comes summer, I would consider shear-stable mineral 85W140 and/or Amsoil SAE 190(which is actually of SAE140 grade,in reference to LE links provided above).
However, I somehow believe that the Amsoil SAE 190's (actually 140's) pour point of -30*C is suitable for use in your -20*C winter regimes (in following year), which you may verify with Amsoil(read
ablo).
