My local distributor is great. They mostly sell to the big guys, but welcome the small guy like me. The guy that sold me the oil yesterday has been there for years and spent 30-45 minutes researching Rotella T for me years ago. Even had a few pages of printout waiting for me when I showed up. I think they'll be there a looong time. That soil has to be extremely contaminated these days.
* They do run a tight ship, but still... It's oil, accidents happen and things spill from time to time.
