Oils with conditioners that are purportedly designed to revive seals and prevent oil leakage, which is a common problem in high-mileage engines, may prove to be more beneficial than other oils.
As they age, internal seals and gaskets can become brittle and shrink to allow oil to seep through. This can be seen as oil streaks on lower engine parts, or oil stains on garage floors or driveways. Motor oil can leach into the combustion chambers if valve-guide seals fail. The engine will then start burning oil. Although small oil leaks may not cause visible blue smoke, the oil level will likely drop to below the maximum mark.
Seal conditioners in high-mileage oils can reduce or eliminate small leaks. They also rejuvenate seals back to their original sizes and shapes. High-mileage oil is not recommended for engines that aren't leaking or burning oil.
If your car has 100,000 miles but uses very little motor oil, it's a judgment call as to whether you should pay more for high-performance oil. It's not harmful and could help prevent any oil from leaking. The majority of vehicle manufacturers will tell you that an engine needs to have oil between oil changes.
High-mileage oils have seal conditioners and more detergents to clean the engine. However, every motor oil claims it can do great things in an engine.
Some mechanics suggest switching to thicker oil (higher viscosity), such as 10W-30 full-synthetic oil, or adding oil additives to prevent leaks. Thicker oil can make it harder for an engine to start in cold conditions. It also reduces oil circulation and increases oil pressure. This means that more pressure will be applied to push the oil past gaskets and seals.
