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 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.
High mileage synthetic oils, on the other hand, are usually manmade, though not automatically.They are often made from natural gas or alcohol, which means they’re pure right from the beginning, and have no undesirable contaminants.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, 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 can come in small, medium or long chains.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.Besides that, synthetic oil can handle high temperatures far better than their more conventional counterparts.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 encourage even longer drain intervals – 25,000 miles max – but this is pretty extreme and experts wouldn’t actually risk it.
More 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 of synthetic oil do come at a price.They’re generally several times pricier compared to old-fashioned lubricants. But the expense is well-justified.Then again, synthetic oils are not all the same, so you have to pick the right product.
