Question: My Camaro is a 1968 model, it has a Saginaw manual 3-speed. I need to drain and replace the lubricant -- can you tell me what weight lube to use? Thank you. By the way, in case it matters, I use the car for street driving only, no racing.Answer: 80W90W Gear Lube is recommended for the Saginaw Manual 3-Speed.
