    That lower unit requires what is called "Hi Vis", available at WalMart, K-Mart, your dealership, any marine type store, etc.

    I don't know anything about the brand name. However "HiVis" is also a 80/90w oil. The name of "HiVis" should appear somewhere on the carton regardless of the brand.

    Unless it stipulates gearcase oil..... don't use it.

    Considering the cost of gears / bearings and shafts + $100.00 / hr if you have to hire a shop, why would you shop for a " cheaper oil " --------------This just is not worth it !!

    Im just asking out of curiousity. Of corse its not about the 5 dollars difference for 1 liter Outboard or car gear oil.
    So im asking myself why there should be such a big difference between these oils.

    There is very little chance of water getting into a car differential !--------------------Look at the size of a car / pick-up differential and compare that to the outboard gearcase !--------------An outboard lower unit is sealed and a car differential is vented.---------Therefor use the best oil for your outboard.------------Technical details would wear out my finger tips on the keyboard.

    LOL That's the coolest wat to say "I dunno" that I've ever heard.

    JeanArr, I've been working on outboards for a living going on 15 years....and I honestly don't know either. If I truly felt compelled to understand it though I could just Google it, as could you. Or you could just buy premium outboard gear lube and leave the "milk vs. cream" details up to the scientists.

    I have repaired outboards and more expensive equipment for about 40 years.----------Most folks do not believe the coaching they get and have their own opinion based on what the friend or neighbor told them !

    Im still working on my second outboard in one year and i dont know the diffrence
    No but thanks you guys Im just going for the outboard oil.

    But maybe we can talk about my 1978 75 hp Evinrude that I am working on right now.
    But there also is an other thread about that.
