Default Hypoid oil

Does anyone know the definition of this commonly used Suzuki term? Its what Suzuki says needs to be purchased from them and installed in specific lower units. If I am correct, it means a HI pressure oil and a SAE 90. Anyone care to weigh in on this? I was planning on using Quicksilver High performance gear lube SAE 90.

Go ahead and use any good marine differential fluid as long as it's API GL-5. Suzuki's is 80W-90, but 75W-90 is okay also. I prefer synthetic in my DF150, but that's up to you.

Default use 80-90W Gl5 oil

I would recommend using the Lucas Oil 80-90W synthetic GL5 oil that you can buy at most automotive stores. I made the mistake of using a 75-90W oil and it burned up my lower unit! I am certain it was the oil as it was black and stinking and the gears were ground up!

Hypoid gears place terrific strain on the contact surfaces. They take a very special blend of oil with properties that don't overheat. I found out later.

Could be good advice. On second look at the synth that I've used since the first lube change, it's actually rated 75W/80W-90. I'd be careful using regular automotive gear lube, however, unless you know it has additives to prevent foaming with water intrusion. Wouldn't want your lower unit to look like this..

Guys, Its my understanding that an oil that has a "W" following the # (Ex. 90W) is not a hi psi oil so not to be used in hypoid app.s . I think only the SAE are truly hi psi oils and that is what makes them a hypoid oil. I am no expert and if I am wrong say so but thats what I learned recently in my quest to find the true definition of a hypoid oil. Thanks for all of your input.

Almost every gear oil made today has the "W" designation, including the Suzuki product. Every differential made today, and as far as I know, every marine lower unit made today utilizes hypoid gears.
