How Often to Change High Mileage Oil


Not sure if you need high mileage oil in your car? You’re not alone. If you searched for “high mileage oil” on the internet you will find over 66 million results. You will most likely see ads, pricing options, several dozen brands to choose from, and thousands of forum posts.

The problem is that there is very little information about what makes the oil “great mileage”, when it needs to be used, or even what the differences are between different brands and options. The purpose of this article is to answer as many questions as possible about high mileage oil.

When is high mileage oil to be used?

High mileage oils contain additives and seal enhancers that reduce leakage (both internal and external). It is possible that after changing the oil or two, the leak will stop. This can reduce oil stains on your road and burn oil in older engines.

How do you work? High mileage oils contain air conditioners and additives that cause o-rings, seals and seals to swell. In some cases, older valve seat seals in engines may have fewer leaks. This can lead to lower oil consumption. Many high-mileage engine oils contain detergents and are designed to remove sludge from engines.

Most high mileage oils are designed for vehicles with mileage of 75,000 miles or more. When you have to change is ultimately your decision, but you have to learn to make the best decisions. If you notice bumps, power loss, cylinder bumps, strange noises, etc., mechanical malfunctions are likely to occur and should be remedied. Long-range oil does not solve these types of problems.

However, if you have a good vehicle with good mileage and are trying to reduce engine wear with realistic expectations, high mileage engine oil may be the right choice for you. Just don’t think that high mileage oil will become a “silver ball” for mechanical wear on your engine.

There is a lot of discussion in the automotive world about how often drivers of typical cars or light trucks have to change oil. Quick lubricated chains usually recommend this every three months or 3,000 miles, but many mechanics will tell you that such frequent changes are not necessary. Most car owner manuals recommend changing the oil less frequently, typically after 5000 or 7500 miles.

According to the automotive website, the answer depends more on the driving pattern than anything else. If you rarely drive more than 16 km at a time (if the oil does not heat up enough to evaporate moisture condensate) or if you start your car often if the oil is not hot (if there is a lot of engine wear), Edmunds should change the oil more often – at least twice a year, even if it is every 1000 miles. Passengers who drive more than 32 km per day on a mostly flat motorway can drive as far between breaks as the owner’s guide recommends, if not longer. More frequent changes can occur as the car ages, but a qualified mechanic must make a decision in any case.

One way to reduce the number of journeys without having to spend money on quick-lubricated sockets is to switch to synthetic oils that last longer and work better than their traditional oil-based counterparts. Davis said trained drivers should choose longer-lasting and more effective synthetic oils that “are likely to last 10,000 to 15,000 miles or six months,” regardless of whether their manufacturers recommend a more frequent replacement or not. Some synthetic motor oils are specially designed for a service life of 40,000 km or one year before the change.
