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 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 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.They’re more stable at a different temperatures as well.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 uniformity.Being impure substances, conventional lubricants are composed of molecules having different lengths.Hydrocarbon chains can be small, medium or 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 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 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 promote even longer drain intervals – up to 25,000 miles – but this is rather extreme and not something experts would actually risk.

Greater Fuel Economy

Better fuel economy makes another way drivers can save cash with synthetic oil. 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, synthetic oils are not all the same, so you have to pick the right product.
