What is High Mileage Oil?

High Mileage Oil is a type of motor oil made for cars that have clocked more than 75,000 miles.

It’s crafted to provide extra safeguarding and to prolong the life of the engine.

This type of oil is different from standard engine oil because it contains a special blend of additives and seal conditioners.

How Does High Mileage Oil Protect an Engine?

High mileage oil can uplift seals that have become shrunken and brittle over time.

Additionally, these lubricants contain seal swellers and conditioners, which contribute to improved engine performance by reducing leaks and smoke.

Clean Engines with Extra Detergents

The use of detergents in high mileage oil can help older engines operate more cleanly.

Engines with high mileage tend to accumulate sludge faster than newer ones.

High mileage oils contains extra cleaners to keep the engine free from dirt and sludge that can build up over time.

Reduce Stress with Increased Anti-Wear Agents

Anti-wear agents are employed to reduce further wear and tear.

Engines with high mileage experience increased deterioration compared to newer ones.

High mileage oils contain compounds that minimize future wear by preventing metal-to-metal contact.

What’s the Difference between Regular and High Mileage Engine Oil?

Regular oil and high mileage oil both do the job of lubricating engines, however, they’re made differently.

The main difference between the two oils is that high mileage oil contains specific additives designed to meet the needs of aging engines.

Regular oil works for many types of vehicles. On the other hand, high mileage oil has special additives that help it use less oil, strengthen the engine’s seals, and stop leaks.

For this reason, it’s the better choice for cars that have been driven for longer periods of time.

Potential Dangers: Can High Mileage Oil Damage Your Engine?
