Well I am of German ancestry, but my people migrated over waayyy before either of the world wars.

If my postings read like technical manuals its because I try to explain things as clearly as possibile. And I am a bit of a nazi about what goes into my car's oil fill. But tearing apart motors and actually seeing the problems the additives and stuff cause will do that to you. Bearings worn down well into to the brass, broken ringlands with pieces of ring in the combustion chamber, etc :laugh:
