I have read on numerous occasions, posts that state a certain brand they use in their vehicle has led to an engine being "more quiet".
Assuming the grade of oil used is the same throughout, can a different brand of oil have an effect on the engine noise and if so, what is it in the oil that aids in decresed noise?
