RE: Follow-Up on Mobil 1 Oil Filters

["Avi Meron" <avi@cosmoslink.net>]

Not quite Michael, a 10W40 becomes 25W or 30W, it always goes towards the
heavy weight, and also keep in  mind, it's not the same for synthetic oil
(most of the synthetic oil I used was single weight, multi viscosity
synthetic oil is an oxymoron, a marketing gimmick), so I have not done any
viscosity tests on synthetic oil.
