I’m looking into using this oil in my next service this week. Currently I have Mag1 5w30 full synthetic in it with a Fram ultra filter. I sample randomly to see how things are looking and the engine seems to be doing good. My wear metals are in range and the car runs great. My only concern is that the oil shears or fuel dilutes to 8.6 in only 2,500 miles. It’s not really hurting anything according to the wear metals but it bothers me. I have some 0w40 SN rated oil from a project left and that’s what the owners manual calls for (SN not 0w40). Do you think it’s worth trying or leave it alone? I attached the PDS from the 0w40.
