Advantages of High Mileage Synthetic Oil
To be aware of the benefits of high mileage synthetic oill, you first have to appreciate how it differs 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.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 often made from natural gas or alcohol, which means they’re pure right from the beginning, and have no undesirable contaminants.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.
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 can come in small, medium or long chains.Synthetic oil is purely made of 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’re a lot better at transferring heat, so synthetic oils can actually even help a vehicle’s engine run 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 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
Improved fuel economy is yet another way synthetic oil can save drivers money.Don’t expect a big increase if you make the switch, but be ready to see an efficiency boost of 2% to 3%.
Of course, synthetic oil benefits don’t come free.They’re generally several times pricier compared to old-fashioned lubricants.The expense is extremely well justified however.Then again, not all synthetic oils are created equal, so it’s important to choose the right product.
