quote:From what I've read elsewhere, when Mobil 1 introduced the Tri-Syn formula, they no longer used a mineral-based additive carrier oil. In the previous formulas of Mobil 1, it was clearly stated on the bottles that the oil was fully synthetic "exclusive of carrier additive oil." The Tri-Syn and SuperSyn formulas don't have this disclaimer.
Originally posted by boxcartommie22: al, are you saying that both mobile full synthetic and delvac 1's carrier oils are 100% synthetic? i know redlines are a total 100% synthetic additive and carrier oil..
