If you own a car with high mileage, then your engine is probably fairly worn at this point. There could be all kinds of issues building up in your engine. The biggest issue is gaps forming in between the engine’s components.
In addition, gaskets and seals will begin to crack over time and cause oil to leak. Then you’ll have oil sludge building up within the engine which can cause all sorts of problems. Just because you heard that Honda and Toyota engines last forever, it doesn’t mean they’re immune to oil leaking issues.
So, what can you do about this? Well, you can take preventive measures by using better motor oil in your engine. More specifically, it needs to be a special kind of motor oil that is made for high mileage vehicles.
The oil will contain additives which can help older engines stay lubricated better and ensure that their seals are protected. Most importantly, the oil will reduce the chances of oil sludge buildup in the engine. As a result, your engine’s lifespan will be extended and you can get many more miles out of your car or truck. You’ll likely even notice a slight performance increase.
