Does High Mileage Oil Help

High Mileage Oil

Have you ever stood in front of a wall of engine oils at your neighborhood auto parts store and pondered whether high mileage engine oil is worth the additional cost? In this post, I will explain what distinguishes high mileage engine oil from traditional and synthetic oils and why you may want to consider using it at your next oil change.

So, is high mileage motor oil cost-effective? If you want your engine to last as long as possible and it has more than 100,000 miles on it, you should use high-mileage engine oil. High mileage motor oil is formulated with unique ingredients to safeguard your engine and extend its lifespan. Some high mileage engine oils can be more expensive than standard oil, but if they extend the life of your engine, the extra expense will be justified. The majority of high mileage engine lubricants are priced similarly to other full synthetic oils. Thus, you can convert to high-mileage motor oil for the same price as a synthetic oil change.


However, if you regularly use conventional oil, switching to high-mileage engine oil will cost you a bit extra. If high mileage oil extends your engine’s life by 100,000 miles, then I believe it would be worthwhile to pay extra for it.


But how much extra does high mileage engine oil normally cost than conventional engine oil?

How much more does high mileage engine oil normally cost? High mileage motor oil is priced similarly to ordinary motor oil. When comparing 5-quart containers of motor oil at my local Walmart, Supertech Conventional 5w-20 motor oil costs $14. A 5-quart container of Mobil 1 full synthetic high mileage engine oil costs $25 at the same Walmart. Which is a difference of almost $10. Therefore, it makes sense to use high mileage engine oil if you currently use synthetic engine oil in a high mileage vehicle. Mobil 1 charges the same price for both their full synthetic and high mileage full synthetic motor oils.


What are the differences between High Mileage Engine Oil and Conventional?

High mileage engine oil is engine oil with additional additives designed to protect high mileage engines. Your engine’s seals and gaskets will begin to deteriorate and shrink over time. High mileage engine oil additives extend the life of your engine by rejuvenating the engine seals and engine gaskets. The majority of high mileage engine oils are suited for engines with over 75,000 miles. If your vehicle has over 100,000 miles on it, I would suggest using high-mileage engine oil. This will extend the engine’s lifespan as much as feasible.


What are the advantages of engine oil for high mileage?

High mileage engine oils are also designed to aid with engine cleanliness. The additives are designed to assist in the removal of engine sludge and carbon buildup. They accomplish this by decomposing the carbon and engine sludge. Then, when you drain your oil the next time you replace your engine oil, all engine sludge and buildup will be removed. High mileage engine oil is also designed to extend the life of your engine. They accomplish this by incorporating compounds designed to reduce friction. This allows your engine to operate more effectively and generate less heat and wear. The seal conditioners included in high-mileage engine oil are its primary benefit. These seal conditioners may prevent the leaks you are experiencing. Additionally, high mileage engine oil may lower the amount of oil consumed between oil changes. If your engine is currently consuming a great deal of engine oil, you may choose to experiment with high-mileage engine oil. It could perhaps minimize the amount of oil you use between oil changes.


What are the disadvantages of engine oil with a high mileage rating?

Depending on the brand you choose, high-mileage motor oil is typically more expensive. Mobil 1’s high mileage engine oil is priced similarly to its standard full-synthetic engine oil. One disadvantage of using synthetic high-mileage engine oil is that you will want to continue using it once you begin. If you use engine oil with a high mileage rating, the additives will begin conditioning your engine seals and attempt to revive them. If you then convert back to conventional engine oil, this may cause your engine seals to contract again, resulting in more engine leaks.


Can High Mileage Engine Oil Help Prevent Oil Consumption?

As your engine continues to degrade over time, the engine seals will begin to deteriorate and will no longer perform as effectively as when the engine was new. This allows oil to skip the piston seals, which finally ends up in the crankcase and is recirculated through the EGR valve. High mileage engine oils are meant to condition engine seals so that they can make a better seal in the engine without replacement. If your seals swell, you will have less blowby from your pistons and your engine will consume less oil.
