High mileage oil incorporates seal swell agents that reverse this drying process, restoring the tension of the seals. Understanding the Difference Between Standard and High Mileage Formulas Conventional motor oil focuses on cleaning and protecting new engine components through robust detergency.
Understanding High Mileage Oil Consumption Reduction
If the engine exhibits no symptoms of degradation and the oil consumption remains within manufacturer specifications, introducing seal conditioners prematurely can sometimes cause more harm than good by interfering with the precise tolerances of a relatively new block. The Role of Seal Conditioners Over time, piston rings and valve guide seals harden and lose their elasticity, leading to micro-gaps that allow combustion gases to leak into the crankcase.
A noticeable drop in fuel efficiency that is not related to driving habits. High mileage oil exists for a specific purpose, yet many drivers remain unsure when to make the switch from their standard detergent blend.
