Advantages of High Mileage Synthetic Oil
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 produced from crude oil.After extraction from the ground, it is extensively refined to eliminate 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 generally manmade, though not essentially.They are often made from natural gas or alcohol, which means they’re pure right from the beginning, and have no undesirable contaminants.As well, they’re also more stable at varying 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.
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.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 longer the oil remains in an engine, the more it thickens.Besides that, synthetic oil can handle high temperatures far better than their more conventional counterparts.And they’re a lot better at transferring heat, so synthetic oils can actually even help a vehicle’s engine run cool.
Since they are more shearing or breakdown-resistant, synthetics are richer than conventional lubricants, and that can pay off really well.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 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. There won’t be a big increase after you switch, but you will likely see get a 2-3% efficiency boost.
Of course, synthetic oil benefits don’t come free.They’re generally several times pricier compared to old-fashioned lubricants.The expense is extremely well justified however.Then again, not all synthetic oils are the same, so you have to take your time picking the right product.
