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 produced from crude oil.Once extracted from the ground, it is thoroughly refined to eradicate impurities.Then it is combined with other chemicals before finding its way to your local auto-parts store.But regardless of the process used, conventional oils always retain a certain level of insolubles, such as silicon, paraffin and other contaminants, which, under specific conditions, may form deposits inside an engine.
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.They’re also more stable at different temperatures.They don’t thin out as much in hot weather or thicken excessively in colder temperatures.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 can come in small, medium or long chains.Synthetic oil only has medium-length molecules.
The problem with conventional oil’s short, lightweight hydrocarbons is that they make it burn in high temperatures. The longer the oil remains in an engine, the more it thickens.Besides that, synthetic oil can handle high temperatures far better than their more conventional counterparts.And they transfer heat better too, meaning they can actually help a vehicle’s engine stay 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 be held out anywhere from 10,000 to 12,000 miles – or three to four times normal oil – while the additional cost of synthetic is nowhere near that.
Some niche oil companies push for even longer drain intervals – maximum of 25,000 miles, but this is quite extreme and hardly something experts will take a chance with.
Greater Fuel Economy
Better fuel economy makes another way drivers can save cash with synthetic oil. 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. But the expense is well-justified.Then again, synthetic oils are not all the same, so you have to pick the right product.
