Severe schedule is 6000kms(regular at 10-12,000kms?) oil and filter changes, which applies to almost everyone in Canada, unless you don't drive in cold, hot, dust, short trips, traffic, driving in rain or sun,etc....
Spark plugs at 160,000km, cvt fluid at 50,000km our ****ty dealer told me dropping the pan and simple pull the plug and refill isn't good enough. But the same dealer also told me they don't have filters in the cvt's as well as other things that make me question their intelligence and what kind of acts they must have to perform in order to keep their job. The manual also called for coolant and brake fluid changes at so many years. I can't seem to find the Canada spec service schedule online. The mitsu canada site is awful and has a bunch of dead links.
I use 0w20, the brown kind.
