What is High Mileage Engine Oil & Intro to AMSOIL High Mileage Oil

High mileage engine oil is a specialized type of lubricant designed specifically for vehicles that have traveled a significant number of miles, typically over 75,000 miles. As engines age, they undergo various changes that can affect performance and reliability. High mileage oil is formulated to address these specific issues, helping to extend the life of older engines.

One of the key features of high mileage oil is its enhanced oil viscosity. Over time, engine seals can become brittle and shrink, leading to leaks and oil loss. High mileage oil contains conditioners that rejuvenate these seals, restoring their flexibility and preventing leaks. This is particularly important as the engine undergoes repetitive cycles of heating and cooling, which can exacerbate seal deterioration.

Another aspect of high mileage oil is its ability to clean and prevent sludge build-up. As engines age, they are more prone to accumulating sludge - a thick, tar-like residue that can clog engine passages and reduce efficiency. High mileage oils often contain detergents and dispersants that help to dissolve and prevent sludge, keeping the engine cleaner and running more smoothly.

When it comes to oil ch ange maintenance, vehicles with high mileage benefit significantly from regular maintenance. The common advice of changing oil every 3,000 to 5,000 miles may vary depending on the vehicle's make, model, and the conditions under which it's driven. For high mileage vehicles, it's especially crucial to adhere to a consistent service oil change schedule. Regular oil changes ensure that the engine is lubricated with fresh oil that hasn't broken down, which is essential for older engines that may be more prone to wear and tear.

Many high mileage oils are available in both conventional and synthetic formulations. Synthetic oil, or syn oil, is engineered in laboratories to have a more uniform molecular structure compared to conventional oil. This consistency helps synthetic oils to perform better in extreme temperatures and to provide superior engine protection. For high mileage engines, full synthetic oil change can offer enhanced protection against wear, better high-temperature stability, and improved fuel efficiency. Premium products that fit this description include the AMSOIL High Mileage product line up.

The role of oil filters in high mileage vehicles cannot be overstated. Oil filters are responsible for removing contaminants from the oil before it circulates through the engine. Over time, as the filter captures more debris, it can become clogged, which can restrict oil flow and reduce its effectiveness. During every oil and filter change, it's important to replace the oil filter to ensure that the engine is receiving clean oil. This is particularly crucial for high mileage engines, as they may produce more contaminants due to increased wear and tear. Amongst the best oil filters for this job is the AMSOIL oil filter.

Choosing the right high mileage engine oil is essential. Products like AMSOIL High Mileage offer specific formulations designed for high mileage vehicles. These "syn oil" products are engineered to provide enhanced protection for older engines, helping to reduce wear, minimize oil consumption, and maintain engine performance. It's important to select an oil that meets the specifications of your vehicle, as indicated in the owner's manual.

In summary, high mileage engine oil is an essential component in the maintenance of older vehicles. Its specialized formulation helps to rejuvenate seals, clean the engine, and provide enhanced protection against wear. Regular oil change practices, including the change of oil filters, are crucial for the longevity and performance of high mileage engines. Whether choosing conventional or full synthetic oil change, selecting the right product for your vehicle is key to ensuring its continued reliability and efficiency.
