Engine oil is the lifeblood of your vehicle’s engine. When the engine is running, the oil pumps through the engine, lubricating the necessary parts to reduce damage caused by friction. It also helps keep specific engine parts cool during hot weather and warm during those cold Corinth, Texas, winter mornings.
Having regular oil changes is essential to help keep your vehicle performing optimally; however, not all engine oil is the same. If you put the wrong type of engine oil in or the wrong weight for the season, you can cause harm to the engine and the parts the oil lubricates. But how do you know what oil to put in your car, SUV, or truck? You can check your owner’s manual, or better yet, bring your vehicle to us at Huffines Kia Corinth so we can be sure to put the right oil in your car’s engine.
Which Oil Should I Put In My Car?
For decades, car owners used conventional oil in their vehicles. However, as vehicle systems became more refined and sophisticated, automakers started demanding different types of oil for their specific needs. As researchers realized that conventional oil is filled with impurities and takes massive amounts of energy to refine, they began developing synthetic and high-mileage oils to help extend the life span of the vehicle’s engine. Engine oil is described using specific terms that are important to understand, including:
- American Petroleum Institute (API) rating: The API categorizes and classifies car engine oil for performance and standards. The API stamp on the motor oil ensures it’s designed to properly use a vehicle’s engine size to protect it from damage.
- Viscosity: Viscosity refers to the thickness of the oil and how easily one can pour it into the engine. In cold temperatures, you’ll need a lower-viscosity oil; at higher temperatures, you’ll need a thicker viscosity. The API develops viscosity rates.
- Weight: You’ll see weights labeled on motor oil, such as 5W-30 or 0W-20. The weight is based on the viscosity rating. The higher the “W” number, the thicker or more viscous the oil is. In colder weather, you’ll need lower-weight or thinner viscosity oil with less resistance during the engine’s start-up period. In hot weather, you’ll want more viscosity.
- Society of Automotive Engineers (SAE): The SAE created a numerical system for grading engine oil weights according to viscosity.
Conventional Oil
This standard engine oil is made from crude oil pumped from underground fossil fuels. Oil refineries use crude oil to remove impurities. They then mix in detergents and various additives to clean it up enough to protect your engine without causing harm from particulate matter or other impurities.
One disadvantage of conventional oil is its life span. When exposed to heat as it passes through the various engine parts, traditional oil begins to degrade. Once it degrades, it loses its protective elements. If your vehicle uses conventional oil, you must change it every 3,000 to 5,000 miles.
Full-Synthetic
Full-synthetic oil is a modern alternative to conventional oil. While the name implies that this type of oil is synthesized, it’s actually not. Synthetic oil is still manufactured from crude oil. However, the refining process is more involved.
During the refining process, impurities are eliminated, and the refinery operators make sure that the oil’s molecules have the same consistent size. This process makes the chemicals in motor oil more stable and can resist oxidation and degradation more than conventional oil. In addition, higher-quality detergents and additives help the engine stay cleaner and more protected. Synthetic oil also lasts longer before needing changing. High-performance vehicles and sports cars perform best with full-synthetic oil.
Synthetic-Blend
Synthetic oil is expensive and requires more to be put into the engine. This may put some people off from using it. Some oil manufacturers today make a synthetic oil blend that offers the benefits of full-synthetic oil without the total cost. Synthetic-blend oil still uses crude oil as a base but goes through extensive refining to remove impurities. It receives detergents and additives of higher quality than those used in conventional oil but is less expensive than those used in full-synthetic oil.
While you still receive some of the benefits of full-synthetic oil, synthetic-blend oil degrades quicker than its full-synthetic counterpart, and you’ll need to change it sooner. The synthetic blend is a viable option for those looking for a middle ground between inexpensive conventional oil and expensive synthetic oil.
High-Mileage Oil
If you drive a vehicle with over 75,000 miles on it, you’ll want high-mileage oil. This type of oil has distinct additives, detergents, and sealers designed to help reduce oil leaks and clean the engine extra. Older engines often produce more sludge than newer ones and need oil with additives and detergents to address this issue and remove the extra dirt and impurities from the older engine.
In addition, high-mileage oil has anti-wear agents that can help protect against future wear and tear of vital engine parts. If your vehicle has a slow oil leak, you must add oil frequently. If it reduces throttle response, have your dealership’s service center inspect the engine and ask them about using high-mileage oil.
