hey fellow Canuck! you can't really go wrong with many of the oils suggested to you here by the fellow members..
but for u to find a product locally and easily at a decent cost and something u can use year round, your options are following
Walmart & Canadian Tire
Mobil 1 0W-40
Mobil 1 TDT 5W-40
Shell T6 5W-40
Castrol Euro 0W-30 (GC)
Castrol 5W-40 (Outdated, not really popular)
Now, one of my buddies has VR6 and he has been successfully using Amsoil SS 10W30
Goodluck!
