Synthetic Oil Vs High Mileage Oil: Comparison

Synthetic Oil for Modern Cars

Synthetic oils are part of routine maintenance, especially for newer car models, SUVs, and trucks. These oils were originally intended to be used for high-performance vehicles, but it’s now being used by mainstream cars.

This type of oil is popular because of its low viscosity, which means it flows smoothly or faster than other oils, which enhances fuel efficiency and car performance.

Newer cars today would actually require synthetic oil. There are tons of advantages to using synthetic oil because it’s a more refined version of regular oil and has special additives that boost engine performance.

It’s also able to cope or perform better even with adverse temperature changes.

However, older cars and high-mileage cars would need high mileage oil. Older cars or those from 1989 or so, can still use synthetic oils provided that the car is in good or excellent running condition and to change the oil filter every time you change the oil.

High Mileage Oil for Older or High-Performance Cars

High-mileage oil is recommended for older cars and high-performing vehicles. It’s standard procedure to switch from synthetic or regular oil to high-mileage oil once your vehicle begins to show some signs of wear and tear or engine problems, especially if there is an oil drip or a loud rattling sound.

Also, you should consider switching to high-mileage oil once your car reaches 75,000 miles.

If your car doesn’t have any engine issues or isn’t encountering any problems in terms of oil leaks or performance, then it is best to stick with your synthetic or regular oil as it’s not API-licensed.

Why High-Mileage Oil Is Best for Older Vehicles

Once your car becomes aged or older and experiences some engine problems or mechanical failure, then you must switch to high-mileage oils that have components or ingredients that are matched to nurture older engine types.

It has antioxidants, conditioners, detergents, seal swells or enhancers, viscosity modifiers, and friction additives that protect your engine for a smooth drive.

The advantage of using high mileage oils is that it protects your car from internal and external leaks and effectively removes sludge clogged in your engine parts.


Regularly changing your oil is imperative for your car to hold up with more miles. After all, experts believe that engine oil is more important compared to fuel.

If you want to use synthetic oil instead of regular oil or high-mileage oil with an older car model, then you must seek professional help. Your car would need to be checked to make sure that it’s in good condition or would need repairs or replacements before using synthetic oil.

Comparing synthetic oil vs high mileage oil demonstrates the importance of a car’s age and performance or overall condition to the engine oil that can bring the best out of your vehicle.
