Your car’s engine is a complex and finely tuned machine, and just like any other machine, it needs the right fuel to run smoothly. That fuel is engine oil. Engine oil is responsible for lubricating moving parts, reducing friction, and keeping your engine cool. Using the wrong type of oil can lead to a range of problems, from decreased performance to engine damage. Knowing how to check what engine oil your car needs is crucial for maintaining its health and longevity. This guide will walk you through the process, providing you with the knowledge to make informed decisions about your car’s lubrication.

Understanding Engine Oil Specifications
Engine oil isn’t a one-size-fits-all product. Different cars require different types of oil based on their engine design, operating conditions, and manufacturer recommendations. This is where engine oil specifications come in. These specifications, often found on a label or in your car’s owner’s manual, provide a code that indicates the oil’s viscosity, performance level, and other important characteristics.
Viscosity
Viscosity refers to the oil’s thickness or resistance to flow. It’s measured in two grades: the cold viscosity (indicated by the number before the “W”) and the hot viscosity (indicated by the number after the “W”). For example, an oil with a viscosity of 5W-30 will flow more easily at cold temperatures (5W) and have a thicker consistency at operating temperatures (30). The correct viscosity for your car is crucial for optimal lubrication and performance.
Performance Level
Performance level refers to the oil’s ability to meet certain performance standards set by organizations like the American Petroleum Institute (API) and the International Lubricant Standardization and Approval Committee (ILSAC). These standards cover factors like wear protection, oxidation resistance, and fuel economy. Common performance levels include “SL,” “SM,” and “SN” for gasoline engines, and “CJ-4,” “CK-4,” and “FA-4” for diesel engines.
Other Specifications
In addition to viscosity and performance level, other specifications may be listed on the oil label, such as:
- API Donut Symbol: Indicates the oil’s performance level.
- ILSAC Symbol: Indicates the oil’s performance level according to ILSAC standards.
- ACEA Symbol: Indicates the oil’s performance level according to the European Automobile Manufacturers’ Association (ACEA) standards.
- Resource Conserving (RC) Designation: Indicates the oil meets certain fuel economy standards.
Finding Your Car’s Engine Oil Requirements
The best place to find the specific engine oil your car needs is in its owner’s manual. This comprehensive guide provides detailed information about your car’s maintenance requirements, including the recommended oil type, viscosity, and performance level.
Owner’s Manual
Your owner’s manual will typically list the recommended oil specifications in a section dedicated to engine oil and lubrication. Look for a table or chart that outlines the recommended oil type for different engine types or model years. Pay close attention to the viscosity and performance level specifications.
Vehicle Information Label
Another good source of information is the vehicle information label, often located on the driver’s side door jamb or under the hood. This label may include the recommended oil type, viscosity, and performance level. However, it’s always best to consult your owner’s manual for the most accurate and up-to-date information.

Online Resources
If you don’t have your owner’s manual or can’t find the vehicle information label, you can often find your car’s engine oil requirements online. Many car manufacturers have websites that provide detailed information about their vehicles, including maintenance schedules and recommended oil specifications. You can also use online automotive databases or forums to search for your car’s model and year to find the recommended oil type.
Checking Your Engine Oil Level
Regularly checking your engine oil level is essential for maintaining your car’s health. Here’s how to do it:
Park on a Level Surface
Before checking your oil level, park your car on a level surface and turn off the engine. Allow the engine to cool down for a few minutes to ensure an accurate reading.
Locate the Dipstick
The dipstick is usually a brightly colored (often yellow) loop or handle located near the engine. Consult your owner’s manual if you can’t find it. Pull the dipstick out and wipe it clean with a rag or paper towel.
Reinsert and Remove the Dipstick
Insert the dipstick fully back into its tube. Remove it again and check the oil level. The oil level should be between the two marks on the dipstick, indicating “full” and “add.” If the oil level is below the “add” mark, you need to add more oil.
Add Oil if Necessary
If you need to add oil, use the recommended type and viscosity specified in your owner’s manual. Add oil slowly, checking the level frequently to avoid overfilling. Overfilling can damage your engine. Once the oil level reaches the “full” mark, reinsert the dipstick and tighten the cap. (See Also: What Happens When Oil and Water Mix in Engine?

Maintaining Your Engine Oil
Regular oil changes are crucial for keeping your engine running smoothly. The recommended oil change interval varies depending on your car’s make, model, and driving conditions. Refer to your owner’s manual for the recommended oil change interval for your specific vehicle.
Oil Change Intervals
As a general guideline, most car manufacturers recommend an oil change every 3,000 miles or 3 months, whichever comes first. However, some newer cars with advanced engine technology may have longer oil change intervals, such as 5,000 miles or 6 months. Always consult your owner’s manual for the most accurate information.
Oil Change Procedure
An oil change typically involves draining the old oil from the engine, replacing the oil filter, and adding fresh oil. You can have your oil changed at a professional service center or do it yourself if you have the necessary tools and experience. If you choose to do it yourself, be sure to follow the instructions in your owner’s manual carefully.
Other Maintenance Practices
In addition to regular oil changes, there are other maintenance practices that can help extend the life of your engine oil and keep your engine running smoothly:
- Check your oil level regularly, as described above.
- Use the recommended oil type and viscosity for your car.
- Avoid short trips, as they can contribute to oil breakdown.
- Drive smoothly and avoid aggressive driving habits, which can put extra stress on your engine.
Frequently Asked Questions
How to Check What Engine Oil My Car Needs?
