I was on Mobil's consumer site, looking for details about their auto oils. Does anyone know if Mobil has any automotive-use lubricants except for Mobil 1 and Drive Clean? I'm asking because I had 21 PPM of Sodium in a recent UOA, and the dealer told me that the oil in that vehicle when I bought it was "Mobil 5w30." This oil was installed in late July 2003. My real concern here is radiator fluid contaminating my oil. PS - Does anyone have an analysis for a Drive Clean or any other Mobil conventional oils sold in the US in the last year? I tried searching the VOAs, but no dice.
