The Different Types of Motor Oil and How They Can Help your Car in Arizona

Last updated 5 years ago

Changing the oil is one of the most basic car maintenance items that every driver learns about, but it might surprise you to learn just how many types of car oil are out there. Most drivers simply assume that one bottle of oil isn’t different from the next as long as it has the same oil ratings, but this couldn’t be farther from the truth. Here’s a closer look at the different types of motor oil and how they can help your car in Arizona:

Conventional Oil

Conventional oil will perform fine under the conditions indicated by American Petroleum Institute ratings on the bottle, but they do not offer optimal lubricity under heavy loads or in high-performance engines. If you have a high-performance engine, you'll want to consider using synthetic oil instead.

Synthetic Oil

Synthetic oil is arguably the best quality oil in terms of long-term performance and resistance to wear. Full synthetic oil is typically only used in high-performance engines, but there are also synthetic blends that offer some of the high-load protection of full synthetics at a significantly reduced cost.

High-Mileage Oil

As vehicles age and accumulate mileage, internal parts and seals become more susceptible to wear, even with regular auto maintenance. High-mileage oils are formulated with more anti-wear additives and with conditioners to help maintain the integrity of rubber seals. These qualities are generally are generally more advantageous than the benefits of full synthetic oil.
