My concern was less about synthetic versus dino (I've read all 24 pages of the "sticky" thread on THAT topic - I should not have mentioned it in my first post, and I apologize :wave: ), but more a curiosity about HOW the MDS "knows" that the engine is pumping the wrong weight/viscosity.
If you use 10w30 instead of 5w20, is it the pressure difference at a specific RPM that mucks up the MDS engagement? And, if so, providing that there's been no coking in the passages, when you swap for the proper weight, does the MDS come back "alive?"
Not at all trying to go against the umpteen manual / TSB references - just wondering WHY they are so adamant about it? Is it "once you use 10w30, your MDS is dead as a hammer for the rest of your life?"
Hmmm.... :33:
