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 derived 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.
On the other hand, high mileage synthetic oils are typically manmade, albeit not necessarily.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.
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 major benefit of high mileage synthetic oil is molecular evenness.Because they are impure substances, conventional lubricants composed up of varying length molecules.Hydrocarbon can come in small, medium or long chains.Synthetic oil only has 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.Aside from that, synthetic oils can also take high temperatures much better compared to conventional lubricants.And they’re better in terms of transferring heat, meaning synthetic oils can help keep a vehicle’s engine cool while running.
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 promote even longer drain intervals – up to 25,000 miles – but this is rather extreme and not something experts would actually risk.
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, synthetic oil benefits don’t come free.They’re typically many times more expensive than traditional lubricants.The expense is extremely well justified however.Then again, not all synthetic oils are created equal, so it’s important to choose the right product.
