I found this today. My question is - would this be suitable for our differential since it's marketed for outboard motors?
The specs seam to be spot on with the manual - SAE 90 GL5 hypoid gear oil...And the blurb on the back seems even more promising "used in hypoid differentials under very heavy duty conditions". Do you guys reckon we have a winner here?
Part nr. : 08251-999-100HE90
How do I know?
Its in my diff right now and was put in 6000 kms ago @ last service.
Works fine.
Its excactly the oil recommended by my (MY00) manual.
I think you've found a winner. I'll bet this is the same fluid that Honda Canada has referred all their dealers to use, but it's labelled for motorcycle use.
Before everyone puts on the funny hats and breaks out the balloons, let's reflect a bit on the hisotry of this entire issue - we have been down this road many times. We always end up in the same place - either there is a mysterious ref to Honda Canada's motorcycle (now Marine?) products, and they always are conventional lubes with high pour points (PP's). That is the whole reason so much investigation, discovery, and analysis was done on a proper replacement. LE-607 is unsurpassed to my knowledge, and I have yet to see where ot failed to deliver.
For cold climates, there is the multi-vis crowd, but a 75 or 80w90 is not even close to a 90w in its high temp capacity. Let alone being out of spec for a part that can, and does, fail when beat on. Prior to 2004, the shotpeened Miata-based diffs are marginal when holeshots are being considered. The Torsen case needs all the help it can get.
I would like to see the Honda Marine's product spec sheet, specifically its volatility and, low temp vis in cST, and especially its pour point. It is a mineral oil, and they typically have PP's in the 20's, F. That may not be a good choice for use in Nevada in the winter, let alone Canada. And its EP? Likely another sulfur compound. Fine, but fine enough?
LE-607 has a PP of -11degF, and a unique, proprietary EP additive with a film strength superior even to moly. Nothing we have seen has its load bearing capacity, in a diff/application that is all about load bearing capacity.
Doubt Honda Japan sources its lubricants from Honda Marine, Canada.
Is it EXACTLY what is spec'ed in the MY00 manual? No part no I'll wager. As I recall, Honda just specs a 90w GL-5, right?
Are there icebreakers using outboards up there? Get it - this is likely a nice weather product not intended for sub-freezing use.
Mobil makes most (all?) of Honda NA lubes. I am off to Mobil's site to see if I can find a spec sheet for a 90w dino diff oil. Well, I looked, and the only low-temp 90w they have is from their SHC line, which is a synoil in a 55 gal drum. I did not see an SAE ratingfor it.
BTW, the Ridgeline specs a 90w GL-5. Wonder what the geniuses at the Dealers are putting in there - VTM4 fluid again?
The Torsen T2 is compatible with automatic transmission fluid
My guess is the ring and pinion need the hypoid oil in SAE 90.

Honda just specs a 90w GL-5, right?
My MY00 German manual specs SAE 90 API GL-5 or GL-6, so yes
The dealership in the Netherlands that put the "marine" oil in my diff has done so for as long as they service S2000's.
Note that the outside temp here doesnt really drop below -15C.
Anyway.. I hope that LE-607 and the other recommended MTL-P are allowed to get airborn as they are my next choice of oils.
