Conversely, a high mileage oil can be based on conventional mineral oil but still deliver the necessary restorative properties. Many drivers assume that any motor oil will suffice once a vehicle passes the 75,000-mile mark, but this assumption overlooks the specific engineering requirements for aging engines.
High Mileage Oil for Reducing Engine Noise in Older Vehicles
If the vehicle has always been serviced meticulously with fresh oil and exhibits no signs of leakage or burning, the standard OEM-spec oil may continue to function adequately. Viscosity: Matching the Oil to the Engine One of the most important factors when switching to high mileage oil is selecting the correct viscosity grade.
Look for products specifically labeled with "Seal Conditioner" or "Engine Restore" to ensure these critical components are present. The defining characteristic is the additive package, not necessarily the base stock used in the formulation.
