High Mileage Synthetic Oil and Its Benefits
To appreciate the benefits of high mileage synthetic oil, you first have to know how it diverges from typical oil.Conventional lubricants are produced from crude oil.After being extracted from the ground, it is extensively refined to get rid of impurities.It is then mixed with other chemicals before standing on the shelf of your local car 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.
On the other hand, high mileage synthetic oils are typically manmade, albeit not necessarily.They are normally sourced from natural gas or alcohol, meaning they’re pure from the get-go, with zero contaminants of any kind.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.
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 key benefit of high mileage synthetic oil is molecular constancy.Because they are impure substances, conventional lubricants composed up of varying length molecules.Hydrocarbon chains can be small, medium or long.Synthetic oil is purely 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 remains 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 better in terms of transferring heat, meaning synthetic oils can help keep a vehicle’s engine cool while running.
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 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
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, the benefits of synthetic oil do come at a price.They’re usually many times pricier when compared to conventional 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.
