Advantages of High Mileage Synthetic Oil
To appreciate the benefits of high mileage synthetic oil, you first have to know how it diverges from typical oil.Conventional lubricants are derived from crude oil.After extraction from the ground, it is extensively refined to eliminate impurities.Then it is blended with other chemicals arriving on the shelf of your local auto-parts shop.However, no matter what process is used, conventional oils always have a level of insolubles, including paraffin, silicon, and other contaminants, which can form deposits in any engine under particular conditions.
On the other hand, high mileage synthetic oils are generally manmade, though not essentially.They are normally sourced from natural gas or alcohol, meaning they’re pure from the get-go, with zero contaminants of any kind.As well, they’re also more stable at varying temperatures.They don’t thin out as much in hot weather or thicken excessively in colder temperatures.Higher VI (viscosity index) equals better oil, meaning viscosity doesn’t change as much with temperature fluctuations, which is a desirable trait.
Also, it’s worth taking note that many refiners produce synthetic blends that are cheaper but weaker in terms of the protection it provides.
Benefits of High Mileage Synthetic Oil
Another key benefit of high mileage synthetic oil is molecular constancy.As impure substances, conventional lubricants are made up of molecules of varying lengths.Hydrocarbon chains can be small, medium and long.Synthetic oil only has 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.Aside from that, synthetic oils can also take high temperatures much better compared to conventional lubricants.And they transfer heat better too, meaning they can actually help a vehicle’s engine stay cool.
Being more breakdown or shearing-resistant, synthetics are way more robust than conventional lubricants, and that is something that can really pay off.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.
Greater Fuel Economy
Better fuel economy makes another way drivers can save cash with synthetic oil. 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 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.
