Guys I just bought a 1987 Toyota Supra Turbo Automatic, and I need to know all the types of oil to put into this puppy. I live in Canada, and I need all the specs because I do not have a manual yet. I suspect the differential is leaking, and I want to fill it up before the ride home. Also if anybody has a diff for sale or knows where to get one for cheap please feel free to tell me. Thanks tons
John
