Chain Case Oil Weight

smo · May 10, 2019

Guys:

Not a question, but a piece of info I got today.

I was looking at the XPS Chain Case Oil and found it annoying that Ski-doo won't publish the weight of that oil on the bottle.

Further, their product safety data sheet was not coming up online, so I used the contact button and asked.

Amazingly, they responded within an hour with an actual answer (and link to the Ski-doo oil...of course).

In an archived thread (which I would have preferred to respond to, but couldn't) I found a bunch of guys saying they use Synthetic 75w90 of various brands and even some saying they use ATF.

According to BRP today, the oil is actually 75w140 (Spec: GL-5, which most gear oils are).

So 75w90 might be a little thin when it warms up...

Just thought I'd forward this to the group.

Happy summerizing! :-(

Ha ha.. that is a pretty light weight or density lube you have in that partial chaincase!.... Not much to wipe up when you pull the partial side cover. Just wish they didn't cost so much!

Yep lots of ATF used in transfer cases with chain link drives.. And even Chrysler used it in their 4 speeds of old.

I sure am glad that BRP has shown an alternative to the chaincase oil. I buy the XPS in 10L so I'm good for a while.

They say you can use 75w-140, but I dont think there XPS synthetic is 75w-140. They state in the accessory catalog that the XPS chaincase oil is not for use in Expedition and Skandic transmissions that require 75w-140?

Like was mentioned, alot of us have used ATF for years. I would think 75w-90 would not be too thin.

Now that is a question worth asking BRP by email. It pays to avoid making the assumption that the info in Shop Manuals or Operator's Guides are absolutes. I have found too many errors over the years to make that assumption. Heck I have a document that I continue building to keep track of them so I don't forget which ones they are and in what documents.

Been using synthetic ATF for decades … I think there is less wear with ATF.

use Lukas 75 140 synthetic and add about 100 ml of oil stabilizer, and NEVER let it idle in neutral.

Ever looked at a truck transfer case chain and gears? Same design as the skidoo stuff.

ATF is used

80w/90, 75w140, or synthetic ATF will work just fine. It's a gearbox. The gear oils may foam at 8k rpm.

I use Ford Mercon V, I prefer the thinner viscosity in cold temps.
