Considering a 5qrt sump, would 1qrt of M1 10w40 added to M1 10w30 be enough to make it higher on the 30 side or 2 qrts? In other words, a 4 to 1 ratio or a 3 to 2 to make the difference?
***Is this a sane thing to try? The engine "seems" to be clicking since switching to M1 10w30. I'm thinking this might help. The truck is due for a scheduled maintenence (120K) so I'll check for clicking after but thought I'd throw this question out there.
