high mileage oil
Aged-motor fluid formula
High mileage oil is motor oil formulated for vehicles with significant accumulated mileage, typically over 75,000 miles.
It contains additives designed to condition aging seals, reduce oil burn-off, and minimize leaks in older engines: I switched to high mileage oil after my car hit 100,000 miles.
The threshold for "high mileage" varies by manufacturer.
