grbr95,
I have used all of Valvoline's different oils but, mainly All-Climate. I like Max Life real well and I am running Durablend in my daughter's car right now. I plan to do a UOA on it whenever my kit arrives. As for the kind of mileage and cleanliness I see with my engines, I have a '95 Dodge Caravan that I bought new. It is about to turn 167,000 miles and all on Valvoline(mostly All -Climate, maybe 15,000 miles with MaxLife,about the same with Synpower).During the Holidays I pulled one of the heads to replace a burned exhaust valve. I found no sludge, in fact, no deposits at all.The cam bearings looked new. As for the lack of moly that you mentioned in your email, other fine oils such as Amsoil and GC are moly free as well.The fact that All-Climate or, any of the others, do not contain moly is not an issue for me. As for the folks that snub their noses at All-Climate, I think they snub without really knowing why they are snubbing!! Thanks for your reply!
