Latest report came back .... decided to give M1 FS 0w40 a shot.. Engine was run pretty much the same as before. Will be going back to valvoline next OCI.
Mobil 1 FS 0w40, RAM 1500 5.7L HEMI 6000 mi, high FE
- Thread starter tcrs_circuit
- Start date
FYI... this is the new 0w40 reformulation.
Was Valvoline used in the previous 4 OCI’s in that report?
I guess the Ram engine likes a stout dose of Molybdenum. Valvoline certainly has that.
I doubt a single ingredient would affect "wear" to this extent. More likely, something is going on with this engine - possibly failing lifter or other internal engine component.
That is a possibility. Cams and liters have been a problem in some 5.7 Hemis.
Time for some thick oil testing... Might get you some more miles out of it.
How does the engine sound? Any abnormal noises?
It’s almost certainly di whereas the Mobil 1 is most likely tri.
What do you mean
Who uses Dinuclear or Trinuclear moly
A recent post about moly by aquariuscsm has me curious...which oils companies are confirmed di or tri moly user? Valvoline for example has been using moly with their latest formulas...which do they use? What about the other major readily available brands Pennzoil/QS, Castrol, Supertech, etc

Completely normal.
Comp 274 on the horizon if so!
C
Previous was Valvoline, the ones before that were shaeffers 9000
Changed oil this morning with valvoline advanced 5w30. Sampling in 3k.
Oil looked normal with no metal?
Affirm.
It could have just been a particle streak or something. Who knows. I'm not worried about it unless the coming interval also shows increased FE.
If you were going to have a lifter failure, it would have happened by now or at least be showing signs. While an individual UOA is statistically worthless, it does nevertheless mirror the oft quoted assumption that Hemis love moly.
