No I agree 100% I'm sure the 0W40 would probably not be a good idea in Canada. But even in TX heat the 40 weight has got to be much thicker than the 20 weight yet the engine sure doesn't notice it. Just my observation anyway.

It's easier to feel the difference in thin and thick oil with a motorcycle. Just run one of the more dense 5-20s if your oem spec is 5-20 and you want to go on the thicker side. Want more protection? Run a synthetic.

You can easily run 5W30 in it! If I lived in Canada I would have a close look at XD in 0W30 it is a great product that I wish mobil would bring to the USA at a good dino price point!

Think they are getting all they can, or just too stupid to order proportionately more of it and make more money?
...Like in the US when you can't get size 11 shoes because "we can't seem to keep them in stock."

To the OP, you could run a thinner 5w-30. Castrol Edge for example, is darn near a 5w-20 in terms of viscosity and has great specs for pumpability at colder temps. I'm sure there are other 5w-30 or 0w-30 oils that are close to a 5w-20.
