High Mileage Synthetic Oil and Its Benefits
To know the benefits of high mileage synthetic oil, you first have to understand how it differs from traditional oil.Conventional lubricants are derived from crude oil.Once extracted from the ground, it is thoroughly refined to eradicate impurities.It is then mixed with other chemicals before standing on the shelf of your local car parts store.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 typically manmade, albeit not necessarily.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 also more stable at different temperatures.They don’t condense as much in cold temperatures nor dilute excessively in warmer weather.The greater the VI (viscosity index), the better the oil, meaning viscosity varies less with temperature, and that is a positive 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 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 and long.Synthetic oil is purely 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 longer the oil remains 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 better in terms of transferring heat, meaning synthetic oils can help keep a vehicle’s engine cool while running.
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 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
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, synthetic oil benefits don’t come free.They’re usually many times pricier when compared to conventional lubricants. But the expense is well-justified.Then again, synthetic oils are not all the same, so you have to pick the right product.
