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 derived from crude oil.Once extracted from the ground, it is thoroughly refined to eradicate 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 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 also more stable at different temperatures.They don’t condense as much in cold temperatures nor dilute excessively in warmer weather.Higher VI (viscosity index) equals better oil, meaning viscosity doesn’t change as much with temperature fluctuations, which is a desirable 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.As impure substances, conventional lubricants are made up of molecules of varying lengths.Hydrocarbon chains can be small, medium and long.Synthetic oil is only made of medium-length molecules.
One thing with conventional oil is that short, lightweight hydrocarbons tend to burn 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.
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 encourage even longer drain intervals – 25,000 miles max – but this is pretty extreme and experts wouldn’t actually risk it.
Greater Fuel Economy
Yet another way synthetic oil can give drivers cash savings is by improving fuel economy. 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 generally several times pricier compared to old-fashioned lubricants.However, the expense is well-justified.Then again, synthetic oils are not all the same, so you have to pick the right product.
