Synthetic Oil vs. Conventional Oil

Synthetic Oil vs. Non-Synthetic (Conventional) Oil

Everyone that has brought his or her car in for an oil change has had to make this decision—do you opt for the cheaper non-synthetic oil, or splurge on the synthetic oil? Most people that decide on buying synthetic oil simply base their decision on the fact that they can usually wait longer between oil changes. But what is the real difference between synthetic oil and non-synthetic oil, and why is synthetic often so much more expensive?

Myths Behind Synthetic and Non-Synthetic Usage

Myths about cars tend to have some historical fact to them. For example, it used to be that cutting off your engine and starting it again wasted more gas than simply letting your car idle. With modern fuel injection technology, however, this is hardly the case.

The same goes for synthetic oil. When synthetic oils were first introduced, they weren’t nearly as advanced as they are today. Switching between synthetic and non-synthetic oils could cause serious engine problems, and sometimes you will hear that you still shouldn’t do this. The truth is that with advanced synthetic oil technology, modern cars can handle the switch just fine.

Synthetic or Conventional

Most car user manuals will suggest a certain type of oil to use in your car, and it’s always best to refer to your manual and your automotive technician on what oil is best for your vehicle.

Synthetic oils are generally better for most modern vehicles. Synthetics don’t break down as quickly over time, which allows you to go more time in between oil changes. The oil can also handle very high temperatures, which keeps oil from burning off and causing engine trouble. Synthetic oil’s ability to handle high temperatures is also one of the reasons it is often recommended for use in high performance vehicles.

Another reason synthetic oil is highly regarded is that it’s thinner than conventional oil. Its thin, free flowing form allows it to reduce friction in engines, leading to better mileage and improved performance. There’s also some evidence that synthetic oil is better for the environment for these same reasons.

So which is better? Generally speaking a synthetic oil will be better for engine both in the short term by lengthening oil change intervals and in the long run for the life of your engine.
