About Motor Oil - Walmart.com

Motor oil plays a critical role in protecting engines and maintaining long-term performance. One of the first things shoppers compare is oil viscosity (0W-20, 5W-30, 5W-20, 10W-30, 5W-40), which affects how oil flows in different temperatures and driving conditions. Choosing the correct viscosity helps ensure proper lubrication, fuel efficiency, and engine protection based on manufacturer recommendations.

Different formulations are designed to meet specific vehicle needs. Full synthetic motor oil offers enhanced performance and protection under extreme temperatures, while synthetic blend motor oil balances performance and value. Conventional motor oil remains a common option for older engines, and high mileage oil is formulated to support vehicles with higher odometer readings. For specialized applications, diesel engine oil (15W-40) and European formula motor oil are designed to meet unique engine and emissions requirements.

Packaging and compatibility are also important considerations when browsing motor oil. Understanding oil volume capacity (1 quart vs 5 quart) helps shoppers purchase the right amount for a complete oil change. Pairing oil with the correct oil filter (pair with oil) supports cleaner circulation and helps maintain engine health between service intervals.

Completing an oil change often requires a few basic accessories. Oil change tools (funnel, drain pan, gloves) make the process cleaner and easier for DIY maintenance. By comparing oil types, viscosities, and supporting accessories, shoppers can quickly find motor oil products that match their vehicle requirements and maintenance routine.

FAQ

Can motor oil be used as lubricating oil?

Motor oil is a type of lubricating oil that is specifically designed for use in automotive engines. It contains additives and detergents that help to protect the engine from wear, reduce friction, and keep the engine clean. While motor oil can be used as a lubricating oil in other applications, such as on machinery or equipment, it may not be the best choice due to its specific properties and additives. Other types of lubricating oils, such as hydraulic oil or gear oil, may be better suited for these applications. It's always best to check the manufacturer's recommendations and select the appropriate lubricating oil for the specific application.

What can old motor oil be used for?

Old motor oil should never be disposed of in the trash or poured down the drain. It is considered hazardous waste and can harm the environment if not handled properly. Instead, used motor oil can be recycled and re-refined for reuse as lubricating oil or other petroleum-based products. In many areas, there are recycling programs or collection centers that accept used motor oil for recycling. Old motor oil can also be used in some other applications such as:

  • As a lubricant: Used motor oil can be used as a lubricant for machinery or equipment that does not require specific grades of oil. However, it is important to filter the oil before using it to remove any contaminants.
  • As a fuel source: Used motor oil can be burned as a fuel source in some furnaces or boilers. However, it is important to follow the manufacturer's recommendations and ensure that the equipment is designed to handle used motor oil as a fuel source.
  • As a weed killer: Used motor oil can be used as a weed killer in areas where it is safe to do so. It is important to apply the oil carefully and avoid contaminating nearby plants or water sources.
  • As a rust preventative: Used motor oil can be used as a rust preventative for tools or equipment that is stored for long periods. However, it is important to ensure that the oil does not come into contact with other surfaces or materials.

What oil cleans engine sludge?

There are a few different types of oils that are designed to help clean engine sludge. These oils contain special additives that break down and dissolve sludge deposits, allowing them to be flushed out during the oil change. Here are some examples of oils that are formulated to clean engine sludge:

  • High-mileage oil: This type of oil is designed for engines with over 75,000 miles and contains additives that help to remove sludge and other deposits.
  • Synthetic blend oil: This oil contains a blend of synthetic and conventional oils and is formulated to clean engine sludge and improve engine performance.
  • Full synthetic oil: This oil is made from synthetic base oils and is designed to provide superior protection against sludge buildup and other deposits.
  • Detergent oil additives: These additives can be added to any type of oil and can help to clean engine sludge and improve engine performance. It's important to note that while these oils and additives can help to clean engine sludge, they may not be effective for severe cases of sludge buildup. In these cases, it may be necessary to have the engine professionally cleaned or rebuilt. Additionally, it's important to follow the manufacturer's recommendations for oil changes and maintenance to prevent sludge buildup from occurring in the first place.
