Benefits of High Mileage Synthetic Oil

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 produced from crude oil.After extraction from the ground, it is extensively refined to eliminate impurities.Then it is combined with other chemicals before finding its way to your local auto-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.

High mileage synthetic oils, on the other hand, are usually manmade, though not automatically.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.

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 chains can be small, medium and long.Synthetic oil is only made of medium-length molecules.

The issue with conventional oil is that short, lightweight hydrocarbons have a tendency to burn off in high temperatures.The longer the oil stays in an engine, the more it thickens.On top of that, synthetic oils are able to handle high temperatures much better than their more conventional equivalents.And they’re a lot better at transferring heat, so synthetic oils can actually even help a vehicle’s engine run 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 encourage even longer drain intervals – 25,000 miles max – but this is pretty extreme and experts wouldn’t actually risk it.

More Fuel Economy

Better fuel economy makes another way drivers can save cash with synthetic oil.Don’t expect a big increase if you make the switch, but be ready to see an efficiency boost of 2% to 3%.

Of course, the benefits offered by synthetic do come at a price.They’re typically many times more expensive than traditional 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.
