AOA I heard somewhere that there is a product that is used to clean engine from inside and mixed with engine oil with some ratio that I dont remember is it true then plz tell me its name and the ratio with which it mix with engine and which engine oil is ideal for this mixing thing
WASALAM
brother what is your ride?
you are talking about ENGINE FLUSH ? it is mixed with engine oil
it is simply additive to engine oil for cleansing the engine deeply
if your ride is a bike it is not recommended , if its a car the ratio is mention on the product of engine flush
for the process , perform under quality mechanic that knows the process
