Benefits of High Mileage Synthetic Oil

To know the benefits of high mileage synthetic oil, you first have to understand how it differs from traditional oil.Conventional lubricants are sourced 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 generally manmade, though not essentially.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 when exposed to hot temperatures or thicken excessively in colder weather.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 uniformity.Because they are impure substances, conventional lubricants composed up of varying length molecules.Hydrocarbon chains can be small, medium or 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 longer the oil stays in an engine, the more it thickens.Besides that, synthetic oil can handle high temperatures far better than their more conventional counterparts.And they’re better in terms of transferring heat, meaning synthetic oils can help keep a vehicle’s engine cool while running.

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 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 encourage even longer drain intervals – 25,000 miles max – but this is pretty extreme and experts wouldn’t actually risk it.

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, synthetic oil benefits don’t come free.They’re generally several times pricier compared to old-fashioned 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.
