Is Synthetic Motor Oil Really Better?

Synthetic motor oil really is better than conventional in many ways. East Coast EuroWerks offers its customers both options, however, because there’s nothing wrong with conventional motor oil. Synthetic offers a few extra things conventional can’t so let’s talk about what those things are so you can make the best decision for your automobile.

Fewer Impurities

Synthetic motor oil has fewer impurities than conventional motor oil has because it is made in a laboratory. That’s right! Scientists make synthetic oil whereas the ground makes conventional oil. Conventional motor oil is extracted from crude, so if you’re an environmentalist, you might not care about anything else. Synthetic motor oil production does not require drilling or fracking.

Because it’s made in a lab, synthetic motor oil contains less contaminants. Conventional motor oil has some contaminants simply because it’s an organic material. All organic materials have contaminants, including you. So, if you’re looking for the purest oil for you engine, you’ll want to choose synthetic the next time you have your oil and oil filter changed.

Better Viscosity

Synthetic motor oil also provides better viscosity for your engine. Scientists put additives in synthetic oil to help it stand up better to internal engine and external environmental temperatures. Conventional motor oil has a shorter lifespan because it loses its viscosity within about 3,000 miles. This is why oil changes are recommended at this mileage duration.

Synthetic does not thicken – or lose its viscosity – as quickly as conventional motor oil does, so it lasts longer between oil changes and stands up to internal and external temperatures better. We don’t really need to worry about extreme heat during North Carolina summers, but viscosity can make or break an engine, so it’s wise to choose an oil that doesn’t thicken easily.


Here’s where most people think conventional motor oil is better: it’s cheaper. If you do the math, however, you’ll see that this isn’t necessarily the case. If you change your motor oil every 3,000 miles but can go 7,500 miles between oil changes with synthetic, the cost will likely be the same. You cut your oil changes in half which makes up for the added synthetic oil expense.
