You can get 5W-40 from Performance Products.
800-243-1220. Call this number for a catalog.
Also -> http://www.************************
Both of the Oils they carry are made by Lubro-Moly. All of their products that I've purchased to date indicate they're made in Germany. Beware! - the 5W-40 oil is $9.95 a liter + shipping.
