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 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.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 derived from natural gas or alcohol, which means they’re pure from the get-go, having no undesirable elements.They’re also more stable at different temperatures.They don’t thin out as much in hot weather or thicken excessively in colder temperatures.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 evenness.As impure substances, conventional lubricants are made up of molecules of varying lengths.Hydrocarbon can come in small, medium or long chains.Synthetic oil is only made of medium-length molecules.
The issue with conventional oil is that short, lightweight hydrocarbons have a tendency to burn off in high temperatures.The oil thickens the longer it stays in the engine.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.
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 safely drawn out from 10,000 to 12,000 miles, or thrice or four times normal oil, while the additional cost of synthetic is not even close.
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
Yet another way synthetic oil can give drivers cash savings is by improving fuel economy.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 usually many times pricier when compared to conventional lubricants.The expense is extremely well justified however.Then again, not all synthetic oils are created equal, so it’s important to choose the right product.
