If high mileage engine got problem like oil disappearing, power loss, running rough with strange noise. The oil additives like liqui moly mos2 actually works, it contain molybdenum which is a super lube will makes minor worn engine running smooth and quiet again.

But do take notes that oil additives which designed to bond a protection layer to the metal will have negative effects if added to dirty oil. When gather dirt it will form sludge then clogged the oil passages or strainer. So must add after oil changes or engine flushing may needed before adding.

Agreed but only can tolerate with 10w 40, higher like 15w 50, 20w 50 will makes engine runs like fetching heavy loads.

Next up want to try mizu ester fully 10w 40, heard ester tech already had the the most of additives functions.
