Hi Matt and Jeff,

        I’m running the same oil as Matt.  I rarely use the vans in the winter so this is fine.

Mobile 15 W 50.

Before that in my old 1.9 I would run 20w/50 from spring to fall before it would get parked in the winter. Wondering what weight I should use for synthetic with temps ranging from about 15C (60F) to 35C (95F). I believe my garage has been using 15W/40 but wanted a third opinion :)
