Advantages of High Mileage Synthetic Oil
To appreciate the benefits of high mileage synthetic oil, you first have to know how it diverges from typical oil.Conventional lubricants are derived 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 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 condense as much in cold temperatures nor dilute excessively in warmer 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, several refiners make synthetic blends, which are generally cheaper than pure synthetics but offer less protection.
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 and long.Synthetic oil is only 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 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 transfer heat better too, meaning they can actually help a vehicle’s engine stay 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 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. There won’t be a big increase after you switch, but you will likely see get a 2-3% efficiency boost.
Of course, the benefits offered by synthetic 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 created equal, so it’s important to choose the right product.
