Considering the climate where you are, I'd be using 5W40 or even 5W50 oils.
I would NEVER use ANYTHING other than Fleece filters (no paper filters).

Every 50,000 to 75,000 miles (100,000 KM) I replace:
Transmission fluid
Differential fluid
Coolant fluid
Brake fluid (it is called "bleeding of brakes")

Replace engine air filters every year (or more often if there is a LOT of dust in the air).

Replace spark plugs and spark plug wires every 100,000 miles (150,000 KM).

Keep battery posts and terminals clean, coat them with protective products.

Replace battery every 48 months/four years.
