I have been in Alberta and I live next to Germany in Holland.
The weather is not the same. But...my V6 needs oil change every 30.000km!
Longlife schedule, they call it.
But it's not only the weather, all conditions are different.
How often do you drive above 100mph (and more)? I don't think you do that every day...
I also remembered how often people have to change the windscreen n Alberta.
Here, they last a liftetime.
This is not a concrete answer for you, but I do not think the conditions can be compared.
