For those of you that still have doubts, Chevron-Texaco has a technical support line: 1-800-lube-tek. Call there and ask for Will Escobar. I have dealt with him on regular basis, and I have also had the pleasure of going to school with him. You can talk to a real person, and get real answers. Will has a wealth of information on additive technology. I believe he can put arest to all the issues, but beware he has a political leaning towrds chevrons strategy of high moly compounds for meeting spec, one that I do not agree with for Passenger cars and light trucks. To me the negatives outweigh the benefits, but that is just my opinion.

I really like they way valvoline durablend and maxlife is formulated. Although maxlife used a stromg moly content, they also dont skimp on he calcium compounds that are necessary for overall high performance in passenger vehicles. I dont see the need for full syn's in passenger vehicle except maybe in turbo applications for extended drains. BUt other than that I like Valv durablend and maxlife(for older vehicles)

I was told that the new Chevron SM oils are using mostly Oronite systems and that they prefer MO to the Borate esters no reason was given tho.
I asked about any "synergy" between CA and borate esters (2 different additves ) and the feeling I got is if there is any synergy they were still verifing if any. BUT Chevron appears to be in the NON borate MO camp.
Also asked about any AW/EP effect from high overbased CA 400 TBN and was told not much improvment seen that MO was better at that.
