Im not buying it either. Cuz how are you gonna put back the viscocity in oil that was lost when it was inside an engine? I know oil breaks down and I wont trust an oil that has been "redone" or "rebuilt" to last like fresh motor oil does.
Back in the 60's we had 'recycled/rejuvenated' CHEAP oil. All our clunker hot rod cars burnt so much oil we used it. I wouldn't put it in my lawnmower now though. IMHO
HOW DO THEY GET ALL THE OTHER STUFF OUT OF THE RECYCLED OIL LIKE BRAKE FUID,TRANS FLUID,ANTIFREEZE THAT GET DUMPED INTO YOUR LOCAL OIL RECYCLE TUB.I WOULD NEVER USE USED OIL THATS JUST CRAZY.
