Benefits 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 sourced 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, 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.

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 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.

Also, several refiners make synthetic blends, which are generally cheaper than pure synthetics but offer less protection.

Benefits of High Mileage Synthetic Oil

Another major benefit of high mileage synthetic oil is molecular evenness.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 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 stays 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 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.

Greater 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 typically many times more expensive than traditional lubricants.However, 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.
