Can anyone tell me where can buy 30W ND (Non Detergent oil) in SFO? I have been
to HD, Lowes, Kragen, Pep Boys and almost every auto spare part store and cannot
find any Non-Detergent oil. The closest oil I can buy is at Sears, they sell
20W (and it may not be ND). I remember O'Relly in the Midwest do sell Shell 30W
ND oil in their stores.

Thanks
