High Mileage Synthetic Oil and Its Benefits

To be aware of the benefits of high mileage synthetic oill, you first have to appreciate how it differs from typical oil.Conventional lubricants are sourced from crude oil.Once extracted from the ground, it is thoroughly refined to eradicate impurities.Then it is blended with other chemicals arriving on the shelf of your local auto-parts shop.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.

High mileage synthetic oils, on the other hand, are usually manmade, though not automatically.They are often made from natural gas or alcohol, which means they’re pure right from the beginning, and have no undesirable contaminants.They’re also more stable at different 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.

As well, note that a lot of refiners make synthetic blends, which are less expensive than pure synthetics but provide less protection.

Benefits of High Mileage Synthetic Oil

Another major benefit of high mileage synthetic oil is molecular evenness.Being impure substances, conventional lubricants are composed of molecules having different lengths.Hydrocarbon can come in small, medium or long chains.Synthetic oil is only made of medium-length molecules.

One thing with conventional oil is that short, lightweight hydrocarbons tend to burn in high temperatures.The longer the oil stays in an engine, the more it thickens.Aside from that, synthetic oils can also take high temperatures much better compared to conventional lubricants.And they’re a lot better at transferring heat, so synthetic oils can actually even help a vehicle’s engine run cool.

Because they are more resistant to “shearing” or breakdown, synthetics are just richer than conventional lubricants, which can pay off big time.The drain interval can safely drawn out from 10,000 to 12,000 miles, or thrice or four times normal oil, while the additional cost of synthetic is not even close.

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

Improved fuel economy is yet another way synthetic oil can save drivers money. You won’t see a huge increase after making the switch, but efficiency can actually get a 2-3% boost.

Of course, synthetic oil benefits don’t come free.They’re generally several times pricier compared to old-fashioned lubricants.However, the expense is well-justified.Then again, not all synthetic oils are created equal, so it’s important to choose the right product.
