The 2018 Toyota Highlander V6 is a popular SUV known for its reliability and spacious interior. Like any vehicle, keeping up with regular maintenance is essential, and one of the most important tasks is changing the engine oil. But how many quarts of oil does a 2018 Toyota Highlander V6 actually take? This guide will provide you with the answer and everything you need to know about oil changes for your Highlander.
Understanding Oil Capacity
The oil capacity of a vehicle is the amount of oil the engine needs to run smoothly. For a 2018 Toyota Highlander V6, the recommended oil capacity is 6.0 quarts. However, it’s important to note that this is just a general guideline. The actual amount of oil your Highlander needs may vary slightly depending on factors such as:
- Oil filter type: Using a different oil filter can affect the amount of oil needed.
- Engine wear: Over time, engine wear can lead to a slight increase in oil consumption.
- Oil type: The type of oil used (conventional, synthetic, etc.) can also influence the oil capacity.
Checking Your Oil Level
Before adding any oil, it’s essential to check the current oil level. This will help you determine how much oil you need to add. Here’s how to check your oil level:
1. Park your Highlander on a level surface.
2. Allow the engine to cool down completely. This is important for accurate readings.
3. Locate the dipstick. It’s usually marked with a yellow or orange handle and is located near the front of the engine.
4. Pull out the dipstick and wipe it clean with a rag.
5. Insert the dipstick fully back into the tube.
6. Pull it out again and check the oil level. The oil level should be between the “Full” and “Low” marks on the dipstick.
Choosing the Right Oil
Not all oils are created equal. The type of oil you use for your 2018 Toyota Highlander V6 is crucial for engine performance and longevity. Here’s what you need to know:
- Viscosity: Oil viscosity refers to its thickness. The recommended viscosity for a 2018 Highlander V6 is 0W-20. This type of oil is designed to provide optimal performance in a wide range of temperatures.
- Synthetic vs. Conventional: Synthetic oil is generally more expensive but offers better performance and protection than conventional oil. It’s a good option for high-mileage vehicles or those driven in extreme conditions.
- API Certification: Look for oils that meet the American Petroleum Institute (API) certification standards. The API certification ensures that the oil meets specific performance requirements.
Performing an Oil Change
If you’re comfortable with basic car maintenance, you can change the oil in your 2018 Toyota Highlander V6 yourself. Here’s a step-by-step guide:
1. Gather your supplies: You’ll need new oil, an oil filter, a drain pan, a wrench, and a funnel.
2. Warm up the engine: A warm engine will help the oil flow more easily.
3. Locate the oil drain plug: It’s usually located on the bottom of the engine oil pan.
4. Place the drain pan underneath the plug.
5. Carefully loosen the drain plug with a wrench. Be careful not to overtighten it when you put it back in.
6. Let the oil drain completely.
7. Replace the drain plug and tighten it securely.
8. Locate the oil filter: It’s usually located on the side of the engine.
9. Unscrew the old oil filter and remove it.
10. Apply a thin coat of oil to the new filter’s gasket.
11. Screw on the new oil filter.
12. Add the correct amount of oil to the engine. Refer to your owner’s manual for the specific amount.
13. Check the oil level and add more if needed.
14. Start the engine and let it run for a few minutes.
15. Check for leaks and re-check the oil level.
Oil Change Frequency
How often you need to change the oil in your 2018 Toyota Highlander V6 depends on several factors, including your driving habits and the type of oil you use. However, a general guideline is to change the oil every 5,000-7,500 miles. Refer to your owner’s manual for the specific recommendations for your vehicle.
Signs of Oil Problems
If your Highlander’s oil level is low or if the oil is dirty or contaminated, it can lead to engine problems. Here are some signs that you may need to change your oil:
- Oil light on the dashboard: This is the most obvious sign that your oil level is low.
- Oil leaking from the engine: Check for any drips or puddles under your vehicle.
- Engine noise: If you hear unusual noises coming from your engine, it could be a sign of low oil or oil contamination.
- Reduced performance: If your engine is struggling to start or accelerate, it could be a sign of oil problems.
Maintaining Your Oil Level
Even if you change your oil regularly, it’s important to check the oil level frequently and top it off if needed. Here are some tips for maintaining your oil level:
- Check the oil level at least once a month.
- Top off the oil if it’s low. Use the same type of oil that you use for oil changes.
- Don’t overfill the oil. This can cause engine damage.
Beyond Oil Changes: Additional Maintenance
While oil changes are essential, they’re just one part of keeping your 2018 Toyota Highlander V6 running smoothly. Here are some other important maintenance tasks:
- Air filter replacement: A dirty air filter can restrict airflow to the engine, reducing performance.
- Spark plug replacement: Spark plugs wear out over time and should be replaced as recommended by your owner’s manual.
- Transmission fluid flush: Transmission fluid lubricates and cools the transmission. It should be flushed periodically.
- Brake fluid flush: Brake fluid absorbs moisture over time, which can affect braking performance.
- Coolant flush: Coolant helps regulate engine temperature. It should be flushed periodically to prevent corrosion.
Final Thoughts: Keeping Your Highlander Running Strong
By following these tips and performing regular maintenance, you can help extend the life of your 2018 Toyota Highlander V6 and ensure it runs smoothly for years to come. Remember to check your owner’s manual for specific recommendations and to address any potential issues promptly.
