The Mileage on & Perceived Tightness of an engine should always be
figured in when deciding on OilWeight ~ Also to be considered is the
fact that TodaysOils are different & MuchBetter than what was
available when the OwnersManuals for our Van's were written ~~ I am a
believer in using a --> 0 to 5 w 30 to 40 Oil <-- in my H2OBoxrs here
in NM & we do get temp's that range from the 100+s down to the
SingleDigi's & some Rare Sub0s ~ I will say that if I lived in PHX, AZ
area in the Summer I might consider running a 5w50 during the
HotMonths ~

        Here is a link to some interesting reading ~ The 1st 4 Chapters &
Chapter 9 are of ParticularInterest
