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 sourced 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.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 made from natural gas or alcohol, which means they’re pure right from the beginning, and have no undesirable contaminants.They’re more stable at a different temperatures as well.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.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 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
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, the benefits of synthetic oil do come at a price.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.
