Motor oil can be considered the lifeblood of your vehicle. It lubricates the moving parts of the engine, reducing friction, minimizing wear and tear, removing impurities, and ensuring a dependable motor every time you turn the key in the ignition. Including routine oil changes in your car maintenance is essential to the longevity and safe operation of your vehicle and prevents the need for costly and complicated auto repairs further down the road. There are three types of motor oil used in modern cars: conventional, synthetic, and synthetic blends. To help you determine which is best for your vehicle, here’s a closer look at the differences between the three.

Conventional

Conventional motor oil is derived directly from crude oil. Its chemical makeup allows it to provide high levels of lubrication even at increased temperatures, like those generated by a vehicle engine. It can maintain its effectiveness over a long period of time, though it does break down faster than the other types of oil discussed here. Some car manufacturers recommend using conventional oil for their vehicles. Check your owner's manual; if you have one of these cars, be sure to schedule an oil change every 3,000 to 5,000 miles.

Synthetic

Synthetic oil starts off as conventional oil but is modified with artificial chemical components that increase its natural qualities and overall effectiveness. Synthetics tend to have better lubricating properties, and they’re better able to maintain their viscous consistency at high temperatures. Since it doesn't break down as quickly as conventional oil, synthetic oil doesn’t need to be changed as often—only about every 7,500 miles or so. Many European cars such as Audis and BMWs require the use of synthetic oil.

Synthetic Blend

Synthetic blends combine synthetic oils with mineral oils. They feature added protection against oxidation and work optimally at lower temperatures. Synthetic blends are cheaper than full synthetic oils, but they often don't have the high-performance capacities of conventional oils. As far as how often to take the car to an auto repair professional for an oil change, synthetic blends fall somewhere in the middle of conventional and full synthetic oils; aim to change oil blends every 5,000 to 7,500 miles.
