I recently had a wreck in my 2013 and the radiator got replaced. I noticed the shop toping the radiator off with Rotella ELC so I suspect they filled the whole thing with that. Is it an OAT product. I am not sure. Several years back I made the mistake of toping this truck off with parts store universal and it wasn't long after that the heater core gummed up. Thus my nervousness on the Rotella?
