So would it be beneficial to run a lower viscosity oil? I thought I read the thicker viscosity oil was beter in warmer climates, plus the 20w50 is the only viscosity in the Vr1 at the auto store.
:thumbsup: that is all, let these other guru's change your mind.
myself I run VR1 20/50 during the summer months in N Idaho .
I believe Chrysler recommended 20/50 for hot summer temps back in the day.
