White substance on dip stick?
So I checked my oil yesterday and the top of my dip stick had some white "fluid" on it. Upon further inspection, it was also on the top of my oil fill neck. Here's a picture of it. Car had sat for about a year and I have done an oil change to it. Any ideas of what it is? Also car is a 1990 with and n/a 13b.

That doesn't look too bad, and the fact that you live in Canada and the car's been sitting makes me think this is completely normal. Does white smoke come out of the exhaust?
If not, The weather changing (getting warmer lately?) is simply separating the moisture/condensation from the oil.
Change your oil, and keep an eye on the dipstick. If the white stuff persists (which I'll bet it won't), then it could be something more serious.
Good luck!

Just clean that out of the filler as best you can.
The best thing is to create better ventilation of the oil system which you can do easily by getting a catch can.

Just water + oil = mayonnaise, yeah, and probably from condensation. Drive it to boil it, condensation gone. It's a rust issue, so you probably need an oil change after a year since it burns up the oil's rust prevention additives, even after 0 miles. Other than that it's no big deal. When storing a car one of the biggest functions of the oil preservative is to add more rust prevention additives. Be sure to always follow this and the many other proper storage procedures whenever you aren't going to drive your car for a while. I'm sure there are guides out there.
If it came from the coolant instead of outside it'd be a whole different story, but this is common from sitting a while in damp weather.

Water condensate in the oil. Take it for at least a 20 minute drive to make sure the oil hits operating temp, it should boil out the moisture. Sounds like you did the oil change after storage? If not, like others said, change it anyway. In a piston engine, getting this sludgy mess on the underside of the oil cap and so on can be a sign of a lot of ring blow-by, but I don't know if there's a comparable issue that contaminates the oil of rotaries.
