I doubt that it really matters, nor do I think the sulfur in some oils 
will make much of a difference unless the DL is operated at elevated 
temperatures for some time.  Typically the problem with those oils is 
water from combustion products forming acid.

BTW if you want mineral oil it is readily available in one quart 
containers at your local airport maintenance facility.  New and rebuilt 
aircraft engines use mineral oil during their break in period.  It's 
been so long since we had a break in period with automotive engines I 
think most people have forgotten.
