hey guys i have a 96 caravan 3.0 with 140k on the clock. lately ive noticed increased lifter ticking and also have a colant leak last uoa showed the oils viscosity was down to a 20wt.any idea of an oil to run until i can get this fixed? i was thinking of gc or a 40 wt.hopefully that would keep the viscosity up but owners manual only shows 5/10w30 as oils to use. thanks guys
