Here in the eastern side of the bluegrass state I like 5w30 in cooler weather and 10w30 in the summer months only.quote:

Not these days ......... the 10w-30 ISLAC GF-3 oils shear down too and I really don't think the sheared vi improvers will sludge a motor with moderate drains given the great D/D additives in most oils today .quote:
