Synthetic vs. Conventional Oil: What’s the Difference and Which Should You Use?

Choosing the right motor oil matters more than you might think. Your engine depends on it to stay clean, cool, and protected over time. If you're wondering whether synthetic oil is worth the extra cost, you're not alone.

Let’s break down the difference between synthetic and conventional oil, when you might need each, and how to make the best choice for your car.

What Is Conventional Oil?

Conventional oil is the original, petroleum-based motor oil. It's refined from crude oil and contains natural impurities and inconsistencies. It does the job for most older vehicles or low-mileage engines, especially if you’re sticking to regular oil changes.

It’s usually the most affordable option, but it breaks down faster under heat and stress.

What Is Synthetic Oil?

Synthetic oil is engineered in a lab to be cleaner, more consistent, and longer-lasting. It’s made from refined base oils and additives designed to reduce friction, resist heat breakdown, and protect engines under high performance or extreme temperatures.

Because of that, synthetic oil:

• Lasts longer between oil changes

• Performs better in cold starts

• Protects turbocharged or high-mileage engines more effectively

It’s more expensive, but it might save money over time with fewer oil changes and better engine protection.

Which One Should You Use?

Here are a few guidelines to help decide:

• Check your owner’s manual. If your car requires synthetic, stick with it. Many modern engines are built with tighter tolerances that need the stability synthetic provides.

• Drive in extreme heat or cold? Synthetic is better at handling temperature swings, especially in Texas summers or icy mornings.

• Drive long distances or tow often? Synthetic oil holds up better under stress and heat from heavy-duty use.

• Just need basic oil for a commuter or older car? Conventional oil is still a solid option if you stick to the maintenance schedule.

Some people also choose synthetic blends, which offer a balance of affordability and improved protection.
