Motor oil is one of the most important fluids in your car. It lubricates engine components so they can move without overheating or wearing down. When it’s time for an oil change, you’ll have to choose between a synthetic or conventional formula. While both products perform similar tasks, they each offer certain qualities that may impact your driving experience. 

How Are Conventional & Synthetic Motor Oil Different?

1. Composition

Conventional motor oil is a refined and distilled petroleum product, meaning it requires fossil fuel drilling that affects the environment. By contrast, synthetic products are engineered in laboratories to provide a more ideal composition for automobiles. Although synthetic products still contribute to pollution when burning, they last longer than conventional formulas and don’t need to be replaced as frequently. 

Both products can be recycled, but drivers may prefer synthetic oil because they can cut down on the number of oil changes they need and limit the amount of pollution they put into the air.

2. Efficiency

Synthetic oils have a lower viscosity, or thickness, than conventional formulas, so they flow through the engine faster and reduce resistance between moving parts. The improved flow rate helps boost fuel efficiency, so you can fill up less often and save money on gas.

Additionally, synthetic products are less likely to thicken when you leave the car overnight. This so-called “cold start” capability means you won’t waste energy or fuel during short trips.

3. Purity

Conventional oil tends to break down over time, leaving sticky solids on engine parts. Without regular oil changes, these impurities can contribute to sludge build-up and affect your engine’s performance.

Synthetic formulas are designed to withstand high heat levels without breaking down and leaving behind impurities that can create mechanical problems and blockages. This is a significant benefit for drivers who strain their engine when hauling loads.

4. Longevity

Conventional oil is the less expensive option upfront, but its tendency to develop impurities shortens its life span. As a result, you’ll need oil changes about once every 3,000 to 5,000 miles, depending on the manufacturer’s recommendations. This can significantly increase your driving costs over time.

By comparison, synthetic oil can work properly anywhere between 7,500 and 15,000 miles, especially if you only take short trips or need to tow heavy loads.
