You guys seem to really like the multi-vis oils.
The truth is that with 10w-30,10w-40,15w-40 and 20w-50 my truck rattles when I start it(392 I.H.C. v8).
Doesn't rattle with Sae 30, holds good oil pressure and uses less oil.
So whats wrong/bad with straight weights?
I live in the desert so extreem cold is not an issue......I saw snow once....On tv
It does get 120 degrees in the summer though.
