Advantages of High Mileage Synthetic Oil
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 produced 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.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.They’re more stable at a different temperatures as well. They don’t thin out as much when exposed to hot temperatures or thicken excessively in colder weather.The greater the VI (viscosity index), the better the oil, meaning viscosity varies less with temperature, and that is a positive 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.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.On top of that, synthetic oils are able to handle high temperatures much better than their more conventional equivalents.And they’re a lot better at transferring heat, so synthetic oils can actually even help a vehicle’s engine run 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 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 push for even longer drain intervals – maximum of 25,000 miles, but this is quite extreme and hardly something experts will take a chance with.
Greater 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 offered by synthetic do come at a price.They’re usually many times pricier when compared to conventional lubricants.The expense is extremely well justified however.Then again, not all synthetic oils are the same, so you have to take your time picking the right product.
