Sorry-as far as I know both Mobil 1 and Delvac 1 have carrier oils. I believe thats also true for Amsoil and assume its true for other PAO/Ester oils. Not sure about Redline and I seem to recall that Royal Purple's latest generation does not have mineral carrier oils. I could be wrong about some of this info.

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..

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.

Before additive technology advanced to what is today, there were no additives that could be directly added to synthetic oils; additives had to be added to Group I oils and then added to the synthetic base oils. Even then, the carriers only comprised <=1% of the total oil. Modern additives can be added directly to synthetic oils as additive companies have additive packages for either dino or synth, and most additives can be added to either or both without an intermediate carrier.

Al, It is possible to incorporate the additive chemistry these days without using petroleum oil as a carrier. I know of at least one company that has been doing this for some time and Mobil may be doing it as well .... TooSlick

The "blenders" order their adds in a large container that uses a carrier or diluent oil. Most offer a PAO or Petroleum diluent oil, guess which one is more expensive ? IMHO, the small amount of petro carrier oil makes little difference in the quality of the final product . For the technically pure it is an abomination !

I've read this to re: M-1's "exclusive of carrier oils" statement. Why do oil companies use mineral oils for their 'carrier oils'??? Why can't they add the addatives directly to the synthetic base oil?? Do they use the same addatives across the board ie. conventional grades and synthetic? eg. does Drive Clean have the same addative package of M-1? Does it differ according to grade?
