Learning The “Secrets” of Cars
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 derived 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, whatever the process used, conventional oils always retain have a particular level of insolubles, like silicon, paraffin, and other natural contaminants, which can form deposits inside an engine under certain 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.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 higher the VI (viscosity index), the better the oil, meaning viscosity is more stable in varying temperatures, which is a good 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 evenness.Being impure substances, conventional lubricants are composed of molecules having different lengths.Hydrocarbon can come in small, medium or long chains.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 longer the oil stays 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 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 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.
More Fuel Economy
Better fuel economy makes another way drivers can save cash with synthetic oil. There won’t be a big increase after you switch, but you will likely see get a 2-3% efficiency boost.
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, synthetic oils are not all the same, so you have to pick the right product.
