Spent 2 months last year doing dust and sand in the outback on a DR 650 that I fitted with a Scott oiler and was very disappointed with the result.
Fitted a new front sprocket in Cooktown and wound the oiler up, like it was nearly empty every day. Figured that if I gave it enough, it would wash the worst away - WRONG!
Mate on an identical setup but with a pre-abused front sprocket was using aerosol chain wax.
By Darwin, my front sprocket was completely shot but his was untouched.
The oiler was a great deal worse than useless in those conditions and used that way.
Went to an aerosol wax after that and had no more problems.
Moral - lots of oil in dust and dirt makes lots of grinding paste.
P.S. I also have a Scotty on my road bike and it's magic!
I may not be as good as I once was, but I'm as good once as I always was.
