Oil Change ServicesYour car’s engine is made up of a lot of moving parts. Naturally, the result of all this activity is a large amount of friction. One of oil’s main jobs is to cool the engine down and keep it from overheating. Oil also cleans and lubricates all these moving parts and protects them from wear and tear.


Like conventional oil, the synthetic variety originates from crude oil. This is where the similarities end, however; while conventional oil is refined from crude oil in the traditional manner, synthetic oil is altered on a molecular level using chemical compounds. The resulting product is higher in quality because the impurities belonging to the crude oil have been removed and replaced by elements that are specifically designed to benefit modern engines.

Unlike conventional oil, synthetic oil’s base is structured without petroleum to let it function without any additives. The additives present are simply to enhance the oil’s performance, not to compensate for lack thereof.

Essentially, oils are categorized into five groups: Groups I and II are created with petroleum as their base and considered conventional oils, while groups III, IV, and V are considered synthetic oils, though group III does begin with a petroleum base.

The chemicals that make up synthetic oil are designed to revert your oil back to its original state, not wear away quickly like conventional oil. These chemicals go through different processes to assure their quality, ultimately offering more benefit for your vehicle.


As you’ve likely gathered, synthetic oil’s artificial nature gives it several distinct advantages. First of all, it is more effective in keeping an Oil Change Servicesengine clean since it takes longer to break down. As oil gets older and begins to break down, it starts to collect various particles of dirt until it all comes together to create a destructive sludge that can seriously damage your engine. Since synthetic oil is stronger, however, it’s able to last longer in order to delay the entire breaking-down process.

With a petroleum base, it’s harder to withstand extreme temperatures as the cold will turn the base into a sticky, sludge-like texture while the heat can thin it out. This is also why conventional oil needs to be changed more often than synthetic oil.

A related benefit is synthetic oil’s natural longevity. As opposed to conventional oil that usually lasts around 3,000 miles before it needs switched out, synthetic oil can last 6,000 to 7,500 miles before being changed.

Synthetic oil also has the ability to withstand extreme conditions more effectively than its conventional counterpart. Whether the outside temperature is frigid or scorching, you can be sure synthetic oil is busy doing its job cleaning, lubricating, and moderating your engine’s temperature.


There’s really no short answer to this question. As most new models (think 2008 and newer) are starting to call for synthetic oil, how often you should change it varies. Usually, it’s somewhere between 7,500 to 15,000 miles, or between six months to a year—whichever comes first.

The best way to find out when your vehicle needs an oil change is to consult your owner’s manual. This will give you the most accurate range so that you can ensure your vehicle is always running in its best condition.


While you might be apprehensive to switch from conventional to synthetic oil, it’ll only be beneficial to your wallet and your engine in the long run. While synthetic oil changes are a bit pricier, they’re less frequent, so you’re ultimately saving money and time spent at maintenance appointments.
