Advantages of High Mileage Synthetic Oil

To know the benefits of high mileage synthetic oil, you first have to understand how it differs from traditional oil.Conventional lubricants are sourced from crude oil.Once extracted from the ground, it is thoroughly refined to eradicate impurities.It is then mixed with other chemicals before standing on the shelf of your local car parts store.However, whatever the process used, conventional oils always retain have a particular level of insolubles, like silicon, paraffin, and other natural contaminants, which can form deposits inside an engine under certain conditions.

On the other hand, high mileage synthetic oils are typically manmade, albeit not necessarily.They are often derived from natural gas or alcohol, which means they’re pure from the get-go, having no undesirable elements.As well, they’re also more stable at varying temperatures. They don’t thin out as much when exposed to hot temperatures or thicken excessively in colder weather.The greater the VI (viscosity index), the better the oil, meaning viscosity varies less with temperature, and that is a positive trait.

Also, several refiners make synthetic blends, which are generally cheaper than pure synthetics but offer less protection.

Benefits of High Mileage Synthetic Oil

Another key benefit of high mileage synthetic oil is molecular constancy.Being impure substances, conventional lubricants are composed of molecules having different lengths.Hydrocarbon chains can be small, medium or long.Synthetic oil is purely made of medium-length molecules.

The problem with conventional oil’s short, lightweight hydrocarbons is that they make it burn in high temperatures.The oil thickens the longer it stays in the engine.On top of that, synthetic oils are able to handle high temperatures much better than their more conventional equivalents.And they transfer heat better too, meaning they can actually help a vehicle’s engine stay cool.

Since they are more shearing or breakdown-resistant, synthetics are richer than conventional lubricants, and that can pay off really well.The drain interval can stretched safely from 10,000 to 12,000 miles, which is three to four times normal oil, while the extra cost of synthetic is far from that.

Some niche oil companies promote even longer drain intervals – up to 25,000 miles – but this is rather extreme and not something experts would actually risk.

Greater Fuel Economy

Yet another way synthetic oil can give drivers cash savings is by improving fuel economy. There won’t be a big increase after you switch, but you will likely see get a 2-3% efficiency boost.

Of course, synthetic oil benefits don’t come free.They’re usually many times pricier when compared to conventional lubricants.The expense is extremely well justified however.Then again, not all synthetic oils are created equal, so it’s important to choose the right product.
