want to change engine oil from liqui moly 10W-40 mos2 to another brand as i have had enough of liqui moly and especially cant find authentic oil in lahore and their SH/SJ isn't impressive.
the only issue is its black in color, so after draining i want to ask is it probable that the new oil will turn black too just because of mos2 and without using engine flush does it even matter that some mos2 remains? as its supposed to mixable with all oils.
also i found out on a bit of research that mos2 is actually not soluble in oil so it should remain down in the oil sump with negligible benefits? and most companies like mobil 1 and valvoline already have this addictive in limited quantities in their oil already.
also mos2 tends to clump together and getting catched by oil filter rather than having big benefits in engine, thoughts?
