A old thread but i wanted to share wath oil i use, probably hard to find in USA, but probably forum members i Europe can get it?
we have here in Sweden a company that makes high end oils that really stand out.
I want the best oil in my engines, and i´m convinced that this is it!!
They work with Schaeffer Oil in USA
