Mobil 1 recommends 0w20 instead of 5w20?

It's not a thick vs thin discussion because at operating temperature those two oils are going to be the same viscosity.

If it were me, and I had another vehicle using 0w20, I'd harmonize on a high quality 0w20 and wouldn't worry about it. Particularly if I lived in a part of B.C. where it gets cold (the inland north I would assume).

West coast bc. Usually only gets down to -10c or so during the winter. Thanks for the input, 0w20 Mobil 1 Ep for both vehicles seems like it should work great for my set up
