        There are a LotOfFolks that say it is OneOfTheBest if not TheBest
but IMHO it is not better enough to justify the Extra$s ~ I'm curious as to
why you are wanting to shift from 15W-50 to 20W-50 as they are both 50weight
oils when WarmedUp & Unless you live in a Climate that is like they get in
the Southern1/2 of Arizona or NM or Texas & you are being told by an
OilPressureGauge that your Eng' is Old&Loose there is no need for the Number
BeforeThe "W" to be any higher than 5 ~
