High Mileage Synthetic Oil and Its Benefits
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 produced from crude oil.Once extracted from the ground, it is thoroughly refined to eradicate impurities.Then it is combined with other chemicals before finding its way to your local auto-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.As well, they’re also more stable at varying temperatures. They don’t thin out as much when exposed to hot temperatures or thicken excessively in colder weather.The higher the VI (viscosity index), the better the oil, meaning viscosity is more stable in varying temperatures, which is a good 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 is purely made of medium-length molecules.
One thing with conventional oil is that short, lightweight hydrocarbons tend to burn in high temperatures.The oil thickens the longer it stays in the engine.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.
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 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
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 generally several times pricier compared to old-fashioned lubricants.However, the expense is well-justified.Then again, not all synthetic oils are the same, so you have to take your time picking the right product.
