I'm out of town and the gear oil for my outdrive is dangerously low. My clear see-thru resevoir is almost empty. There's an auto parts store within 5 miles. What oil do I buy? 75-90 Mobil 1 synthetic gear oil? I called the dealer and they said to only run "Mercruiser" or "Quicksilver" gear oils. I'm not dumb, as long as an oil is the same weight and viscosity it's interchangeable. They wouldn't give me the weight, or they didn't know it? (Which I find hard to believe.) Oh, did I say I left my manual at home like a frickin' genious? What do you think?:huh:
