Which engine oil leave the least deposit ?

[kr_bitog]

I wonder which engine oil burns cleaner in the case they go to combustion chamber ?
The reason I ask is, for certain engines high speed rpm will cause engines burning oil, so which oil will be the best for those engines ?
Does the mineral burns cleaner than synthetic, or it depends on the additive package ?
Thank you

Synthetic would burn cleaner as it also starts cleaner to begin with. My guess is a group V or ester based would burn cleaner as they are used for premium 2 cycle oils and in biodiesel.

Wait for ashless oils.

Gary has a Jedi way of saying things so you are learning without knowing it on the normal awareness level......

Bottom line: With any modern motor oil, any (minimal) deposits in the combustion chamber will be from additives of the ash variety, those bearing "soft" metals (Ca, Zn, P, Mo….). Not the base oil, regardless of type.
