It's a 15W-40 diesel oil. I suspect it has more ZDDP than auto oil, 
but, again, that's an assumption based on the fact that it meets some 
earlier specs. I add some Lucas supplement to it. The Lucas 
supplement come in bottles that cost $10 and will cover 2 oil 
changes.

I'm still not convinced that excess zinc would cause more wear.
