Advantages of High Mileage Synthetic Oil
To know the benefits of high mileage synthetic oil, you first have to understand how it differs from traditional oil.Conventional lubricants are produced 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.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.
On the other hand, high mileage synthetic oils are generally manmade, though not essentially.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.Higher VI (viscosity index) equals better oil, meaning viscosity doesn’t change as much with temperature fluctuations, which is a desirable trait.
As well, note that a lot of refiners make synthetic blends, which are less expensive than pure synthetics but provide less protection.
Benefits of High Mileage Synthetic Oil
Another key benefit of high mileage synthetic oil is molecular constancy.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.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 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.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 of synthetic oil do come at a price.They’re generally several times pricier compared to old-fashioned lubricants.However, the expense is well-justified.Then again, not all synthetic oils are created equal, so it’s important to choose the right product.
