Is High Mileage Oil Worth it?

Yes there is no doubt that it is essential to use high mileage engine oils. The thing is that with age, your vehicle’s engine naturally begins to show signs of wear and tear. Using high-mileage oil can help ensure your engine runs optimally and lasts much longer over time.

When it comes to choosing an oil for your car, there are many types to choose from – conventional, synthetic and blends. High mileage oils tend to be pricier than standard options but may be worth the investment for older cars.

One advantage of high-mileage oils is that they can reduce oil leaks in older engines. It is safe to say that these oils contain seal conditioners which cause gaskets and seals on mating surfaces to swell, thus reducing internal and external leakage.

How Does High Mileage Oil Work?

As your car’s age it begins to show in their appearance. The engines may start to deteriorate and lose power and efficiency, while other components may start to malfunction or even break down entirely.

How Does Engine Benefit From High Mileage Oil

As you already know, high mileage oil is said to do an amazing job when it comes to assisting older engines (generally those with over 75,000 miles).

These oils benefit the engine by keeping its parts lubricated and refreshed. This reduces smoke, emissions, and leaks that older cars tend to produce.

As vehicles age, gaskets and seals often loosen. To combat this problem, higher-mileage oils are designed with seal conditioners to enhance flexibility and restore shape to these parts.

As you can see, high mileage engine oil is designed specifically for vehicles that has tons of mileage on them since it helps to protect them from wear, sludge and leaks over time.

Traditional and high mileage oils differ in their additive concentrations. High mileage oil enhanced detergent systems help combat deposits that cause engine failure, while seal conditioners keep rubber seals flexible to prevent future leaks. These features are typically tailored for older vehicles with extensive mileage on them as these qualities help extend their engine’s life expectancy.
