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 combined with other chemicals before finding its way to your local auto-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.
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 condense as much in cold temperatures nor dilute excessively in warmer weather.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.Being impure substances, conventional lubricants are composed of molecules having different lengths.Hydrocarbon chains can be small, medium and long.Synthetic oil is only made of 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.
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 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
Better fuel economy makes another way drivers can save cash with synthetic oil. 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. But the expense is well-justified.Then again, not all synthetic oils are the same, so you have to take your time picking the right product.
