High mileage oils are special oils for engines of older cars that have seen their fair share of roads and trips. Such oils contain additives and certain seal enhancers that try to prevent and reduce internal and external oil leaks from your engine. This can help with those annoying oil sports on your driveway, as well as with burning of the oil in older engine models.

Simply put, high mileage oils work in such a way that their special ingredients make o-rings, gaskets, and seals swell up. In addition, most high mileage oils contain detergents capable of removing built up sludge from the engines from years of use, allowing better flow.

It is generally considered that cars with more than 75,000 miles on their dash could benefit from high mileage oils.

There are no clear guidelines or rules to when high mileage begins on a car, especially now that modern vehicles can last up to 400,000 miles before experiencing serious problems. In addition, highway miles are not the same as city miles, evident by the two different fuel economy standards. On the highways, there are much less stops and starts, resulting in steadier temperatures and less wear and tear of the engine. Besides, the engine works at its peak for longer. In the city, things are very much on the opposite end, and an engine with 80,000 city miles might be in worse condition than an engine with 150,000 highway miles. The vehicle type and maintenance also paly big roles.

Generally, most people switch to a high mileage oil when they cross 200,000 miles, but there are also those who want to care more for their vehicle and make the switch at 80,000. This puts the average amount of miles at anything over 100,000. For used, old-timey cars, it is best to switch as soon as possible in order to get the maximum out of it before completely gives out on you.

It could be said that the engines themselves are actually the ones that should bear the name “high mileage”. Anyway, it is not easy to answer this question mostly due to the fact that not all cars are in same condition, and not all of them have the same kind and the same total of miles behind them.

That being said, the newer the car, the less oil changes it needs. This means that if your vehicle has a good engine that has enjoyed proper maintenance for years, you do not have to do it that often. You could always do an oil analysis to check the situation.

For old and used cars that are prone to oil burning, oil changes should be a regular occasion. The engine is already suffering from tens, if not hundreds of thousands of miles, so do not roughen it up more with rare oil changes. If you want your scrappy car to make it a little bit longer, perform oil tests and checkups regularly and pay attention to any strange situations in the car’s overall performance.

Therefore, try to do as much research as possible before making the final decision on the high mileage oil you need.
