Funny that you have brought this up Wemay. I have been thinking about running Mobil Super Synthetic 5w30 only in my Altima. I can find it regularly at AAP or O Reilly's. I don't mind Wally World but I would rather not have to walk around that place if I don't have to. Some days I just don't have it in me to work all that far. Other days I can do it with no problems. But if I can go to O Reilly's or AAP it makes it nice to be able to be in a MUCH smaller store. I like having a smaller place to go to. Mobil Super Synthetic runs rather good in my car. Havoline Pro DS disappearing has had me wanting to find it's replacement. I certainly liked Valvoline as well. For the lady's Camry it will stay on Valvoline Maxlife Full Synthetic and Rislone for the rest of it's time with me. That combo runs very, very quiet and even better than Motorcraft. Which that's impressive because Motorcraft ran a fair amount quieter than Havoline and PYB before in it. So that is settled on the Camry. The Altima may well stay on MSS. However, it may see Valvoline Synpower be or VWB as well.
