HIGH MILEAGE OIL IS GOOD FOR ENGINES

Updated: Nov 15, 2023

High mileage motor oil is a type of engine lubricant specifically formulated to meet the needs of vehicles that have covered a significant number of miles. Generally, this means cars, trucks, and SUVs that have traveled 75,000 miles or more. As vehicles age, their engines can suffer from a range of issues due to wear and tear, and high mileage oil is designed to address these problems, helping to extend the life of older engines.


The formulation of high mileage motor oil is distinct from regular motor oil in several key ways. First, it typically contains a higher viscosity to help maintain a strong oil film between engine parts, reducing wear. This is particularly important for older engines where component tolerances may have widened due to wear. Oil viscosity is a critical factor in ensuring that the oil can effectively protect engine components under different operating conditions, from cold starts to high-temperature operations typical of city car driving.


Another aspect of high mileage oil is its additive package. These oils often include conditioners that can rejuvenate seals and gaskets, reducing leaks that are common in older engines. They also have more detergents and dispersants to clean sludge and deposits, and additional anti-wear additives to help protect aging engine parts.


For fleet mechanics who manage multiple vehicles, such as fleet vehicles used in businesses or governmental organizations, choosing the best synthetic oil for high mileage vehicles is crucial. These vehicles often operate under more demanding conditions than the average everyday driver's car, making the protective qualities of high mileage oil even more important.


Synthetic engine oil, in particular, offers several benefits over conventional oil, especially for high mileage engines. Synthetics generally have better high and low-temperature performance, ensuring better protection during cold starts and under high engine load conditions. The benefits of synthetic oil include improved engine cleanliness, better protection against oil breakdown and oxidation, and extended oil change intervals, which can be a significant advantage for both individual owners and fleet operators.


For those driving naturally aspirated engines, high mileage oil can offer enhanced protection. This is also true for vehicles like pickup trucks that may be used for towing or carrying heavy loads, putting additional stress on the engine.


For the DIY mechanic, high mileage oil can be a good choice for extending the life of an older vehicle. Performing a DIY oil change with high mileage oil can be a cost-effective way to maintain an older car, especially when looking for the best oil for high mileage vehicles. For those who prefer professional service, finding an oil change near me facility that offers high mileage oil change services can provide the necessary expertise and convenience.


AMSOIL, a well-known brand in the synthetic oil market, offers a lineup of AMSOIL High Mileage motor oils, including the popular AMSOIL 5W30, that are designed to meet the needs of older vehicles. Using the AMSOIL Lookup Guide, vehicle owners can easily find the right type of high mileage oil for their specific make and model, ensuring they get the best possible protection for their engine.


In conclusion, high mileage motor oil is an essential product for anyone looking to maintain an older vehicle. Whether you're a fleet mechanic managing multiple high-mileage vehicles, an everyday driver looking to keep your aging car running smoothly, or a DIY enthusiast performing your own oil changes, choosing the right high mileage oil can make a significant difference in the performance and longevity of your engine. With the advanced formulations available today, including synthetic options like those offered by AMSOIL High Mileage oil, older engines can continue to operate effectively and reliably, even as they rack up more miles.
