it hasn't yet shown its dislike for the formulation.

sabi ng isang auto journalist,
what's advantageous with mineral oil, is that one is forced to do 5000 or less km, oil changes.
when one changes oil, all the gunk and minute metal filings, are removed from the engine. this is something those synthetic oils and their longer oil change intervals, can not claim to.

well if you read the manual it says 10k interval for MINERAL oil under normal schedule. so yeah the mfg isn't forcing you to do 5k oci

but i get what you're saying. my intuition says, coz i'm not a tribologist and none of you are, that most people are shooting themselves in the foot by doing extended drain intervals when using their expensive synthetic oils. it's probably better to change more often using cheaper oil
