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 sourced 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.But regardless of the process used, conventional oils always retain a certain level of insolubles, such as silicon, paraffin and other contaminants, which, under specific conditions, may form deposits inside an engine.
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.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 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 key benefit of high mileage synthetic oil is molecular constancy.Being impure substances, conventional lubricants are composed of molecules having different lengths.Hydrocarbon chains can be small, medium and 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.Aside from that, synthetic oils can also take high temperatures much better compared to conventional lubricants.And they’re a lot better at transferring heat, so synthetic oils can actually even help a vehicle’s engine run cool.
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 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.Don’t expect a big increase if you make the switch, but be ready to see an efficiency boost of 2% to 3%.
Of course, the benefits offered by synthetic do come at a price.They’re typically many times more expensive than traditional lubricants.The expense is extremely well justified however.Then again, synthetic oils are not all the same, so you have to pick the right product.
