High Mileage Synthetic Oil and Its Benefits
To know the benefits of high mileage synthetic oil, you first have to understand how it differs from traditional 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.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 often derived from natural gas or alcohol, which means they’re pure from the get-go, having no undesirable elements.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 major benefit of high mileage synthetic oil is molecular evenness.Being impure substances, conventional lubricants are composed of molecules having different lengths.Hydrocarbon chains can be small, medium and long.Synthetic oil only has 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.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 be held out anywhere from 10,000 to 12,000 miles – or three to four times normal oil – while the additional cost of synthetic is nowhere near that.
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.
More 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 typically many times more expensive than traditional lubricants. But 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.
