In Vancouver you shouldn't need a block heater. 0w-5w and 30-40-50 weight oils should all be ok. There's a forum in here somewhere talking about oils that's pretty good. There's filter info on line, that's quite helpful too, you might want to check them out for up to date comparisons. For tires, I got the coopers too, they seem ok and I live just north of you in Squamish. Gl. I got my dads 89 mx6 gt, but no 4ws, a while ago when he was told not to drive any more. "gettin to old" lol. I like "mine" too. And the all important 4ws question was answered in this forum and I agree 'it should be better' and I haven't seen anywhere that sais other wise.
