so for a 95 turbo diesel jetta with 225k km in Vancouver/Seattle I should buy 20W 40?

it's always safer to go with a thinner oil on a diesel in case it gets cold for only a couple freak days.

In your car (the 95 TD) you can use 15w-40 all year round. Most autoparts sell 1 gallon jugs of Valvoline "Premium Blue" for around $13 USD. That's what I have used in my diesels since the beginning of time... in fact did an oil change today with this exact oil.
