High Mileage Oil

High mileage oil is designed to work best on engines with more than 75,000 miles. Today's engines are designed to last longer, but high mileage oil helps protect these engines from deposits which may corrode the engine, while also providing a sealant to help reduce leaks. This can result in better performance, improved fuel mileage and extended engine life.

High mileage oil typically contains more detergents, conditioners and sealants than traditional oil. This helps reduce the break-down of components and helps protect the engine from corrosion. High mileage oil is higher in viscosity, giving it better lubricating properties and delivering greater oil pressure.

Regular Oil

Traditional oil is typically used on engines with less than 75,000 miles. It provides a necessary lubricant for the engine's moving components and helps reduce deposit build-up and engine wear. Regular oil also helps provide rust prevention to engine components and helps maintain a clean engine.

Regular oil is also often less expensive than high mileage oil. You won't have to worry about investing in extra conditioners or sealants. Regular oil just needs to be changed more frequently than high mileage oil.

Properties of High Mileage and Regular Oil

High mileage oil is specially formulated for use in older engines with higher mileage. It is designed to help prevent engine sludge and deposits, which can be a common problem in older engines, and to help reduce engine wear and tear. High mileage oil contains special detergents, dispersants and other additives to keep the engine free of sludge and other deposits. It also contains conditioners to help reduce leaks and to replenish seals.

Regular oil, on the other hand, is designed for use in newer engines with fewer miles. Its main property is that it keeps the engine lubricated while in use; it does not contain the same detergents and conditioners as high mileage oil, so it is not formulated to prevent sludge or aid in the prevention of leaks and seal damage.
