Benefits 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 sourced 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.But regardless of the process used, conventional oils always retain a certain level of insolubles, such as silicon, paraffin and other contaminants, which, under specific conditions, may form deposits inside an engine.

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 when exposed to hot temperatures or thicken excessively in colder weather.Higher VI (viscosity index) equals better oil, meaning viscosity doesn’t change as much with temperature fluctuations, which is a desirable trait.

Also, it’s worth taking note that many refiners produce synthetic blends that are cheaper but weaker in terms of the protection it provides.

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 or 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 stays in an engine, the more it thickens.Aside from that, synthetic oils can also take high temperatures much better compared to conventional lubricants.And they transfer heat better too, meaning they can actually help a vehicle’s engine stay 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 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, synthetic oil benefits don’t come free.They’re generally several times pricier compared to old-fashioned lubricants. But the expense is well-justified.Then again, synthetic oils are not all the same, so you have to pick the right product.
