Kevin;
        In a normal engine that would be a straight forward question.
Some WBX engine need thicker than normal oil. There are certain filters
which exacerbate the oil light flicker at hotter temps. Fram seems to be
one of them. I use 20W50 Castrol during the hot months and 10W40 during
the cold. I use el cheapo FLAPS filter and shoot for 2K mile oil change.
200K+ miles later it seem to be working out OK.

Good Luck and Drive Safely
