Which Motor Oil Is Right At An Oil Change?

It’s time for an oil change! But when you get to Performance Auto, you notice there are four motor oil types: Full synthetic, synthetic blend, conventional, and high mileage. Which does your car need? What’s the difference between them all? Here’s the skinny on each type and what they are best used for!

Which Oil Type Is Best For You?

Full Synthetic Motor Oil

Full Synthetic is the purest type of synthetic oil and is extremely refined mineral oil. Full synthetic is recommended for cars that need high performance and higher levels of lubrication. Due to the high levels of viscosity and resistance to oxidation, you’ll see less oil sludge and better fuel efficiency.

Synthetic oil costs somewhere between 2 and 4 times more to create than regular oil, and thus, will cost more at oil changes. However, the benefits may outweigh the price. For older engines, full synthetic oil may help extend its life as it helps prevent the sludge built up that tends to happen in older cars. The time you can go between oil changes may also be worth the cost as some full synthetic brands can go up to 10,000-15,000 miles before needing another change. We suggest reading your owner’s manual or talking to one of our mechanics for an exact number.

Synthetic Blend Motor Oil

Synthetic Blend is semi-refined mineral oil and is less refined than full synthetic. Synthetic blends marry synthetic and conventional oils, bringing some benefits of full synthetic, but as a much lower price point. You’ll find conventional oil as the base, but with additives that bring resistance to oxidation and have lower temperature properties.

Synthetic blends are much better on a standard engine and have less impurities than conventional oil, so you can go longer between oil changes. Though you can’t go quite as long as you could with full synthetic, an average car can run about 6,000 miles comfortably with a blend, or about 6 months.

Conventional Motor Oil

Conventional Oil has been the standard for years when it came to oil changes. In the early life of a car (under 5,000 miles), conventional oil is still recommended as introducing synthetic oil too soon after being manufactured may decrease your car’s performance. The biggest advantage conventional oil brings to the table is its price. This type of oil is significantly less expensive than any synthetic oils. Synthetic oil may be 6-10 times higher than conventional oil, which is very appealing at an oil change.

High Mileage Motor Oil

If you see 75,000 miles or more on your odometer, high mileage oil is what you need. The composition of this type of oil is designed to slow the aging process of your engine and extend the overall performance of your car. It will help reduce leaks, lower the oil consumption and condition the seals of the engine in an older car.
