Hi,
I understand that sometimes when an oil is sold under various names, but all made by one oil company, an additive tracer is added to be able to distinguish. Is this often the case?
Does anyone know if this is done with the Delvac1 / Cat Full synth 5w-40 (whose msds is supplied by exxonmobil)? I as this because my analysis for my 83 diesel shows 11ppm of moly in the oil. This is after the second drain of D1. The only difference was the first fill was d1 from a canadian wal-mart, and the second was caterpilliar full synthetic 5w-40. Overall my car had these two fills in for 10k miles.
I knwo that mobil-branded delvac 1 has no moly, according to the VOAs on this site. So thats why Im wondering if CAT maybe adds moly as a tracer. (I had rotella T in there before, which doesnt have moly, so there were three fills at least with no moly additions...
Any info would be appreciated. thanks
