Start by loosening the lug nuts, lifting the vehicle, and securing it with stands. Following a pattern, such as front-to-back or side-to-side, switch the tires’ positions. Reinstall the lug nuts and lower the Subaru Ascent safely.
These DIY tips empower you to maintain your Subaru Ascent efficiently. Knowing how to change the oil and rotate the tires will save you time and money. Next, we’ll explore other essential maintenance tasks like fluid checks and brake inspections to ensure your vehicle’s optimal performance.
What Is the Importance of Oil Changes and Tire Rotations for a 2018 Subaru Ascent?
Oil changes and tire rotations are crucial maintenance tasks for the 2018 Subaru Ascent. Regular oil changes involve replacing the old engine oil with new oil to ensure smooth engine operation. Tire rotations involve moving the tires from one position on the vehicle to another to promote even tire wear.
According to Subaru’s maintenance guidelines, these practices are essential for maintaining vehicle performance and longevity. The American Automobile Association (AAA) also emphasizes that regular maintenance directly influences a vehicle’s reliability and safety.
Oil changes ensure that engine components remain lubricated and free of debris. Fresh oil improves fuel efficiency and reduces emissions. Tire rotations help maximize tire lifespan, enhance traction, and ensure even wear across all tires, which is particularly important in all-wheel-drive vehicles like the Subaru Ascent.
The National Institute for Automotive Service Excellence (ASE) defines tire rotation as an important service that helps extend tire life by balancing wear across all four tires. This practice addresses the fact that front tires generally wear out faster than rear tires due to steering and weight distribution.
Routine oil changes and tire rotations are often neglected, leading to issues such as decreased engine performance and shorter tire life. The Car Care Council reports that neglecting regular oil changes can lead to engine damage and reduced vehicle efficiency.
The consequences of ignoring these maintenance tasks can include costly repairs and reduced vehicle safety. Poorly maintained vehicles can contribute to accidents and environmental pollution due to higher emissions.
From a health perspective, a well-maintained vehicle reduces the likelihood of breakdowns on the road. Environmentally, improved fuel efficiency leads to lower emissions. Society benefits from safer vehicles, while the economy thrives on reduced maintenance costs.
For effective vehicle maintenance, both Subaru and the AAA recommend adhering to service schedules, using quality products, and consulting professionals when necessary. Regular inspections can also help identify potential issues early.
Technologies such as oil life monitoring systems and tire monitoring sensors can assist drivers in keeping track of maintenance needs. Additionally, education on maintenance can empower owners to take proactive steps for their vehicle’s health.
How Can You Tell When It’s Time for an Oil Change and Tire Rotation in a 2018 Subaru Ascent?
You can tell when it’s time for an oil change and tire rotation in a 2018 Subaru Ascent by monitoring the vehicle’s mileage and observing its oil life indicator, as well as checking the tread depth and wear pattern of the tires.
For oil changes, refer to the following guidelines:
- Mileage Interval: Subaru recommends changing the engine oil every 6,000 miles or 6 months, whichever comes first. This interval helps maintain optimal engine performance.
- Oil Life Indicator: The 2018 Subaru Ascent features an oil life monitoring system. This system calculates the remaining oil life based on driving conditions. If the oil life indicator displays a low percentage, it’s time for an oil change.
- Oil Consistency: Check the oil’s color and texture. Fresh oil is amber-colored and smooth, whereas old oil may appear dark and gritty, indicating it needs to be changed.
For tire rotations, consider these factors:
- Mileage Interval: Schedule a tire rotation every 6,000 to 7,500 miles. This practice ensures even wear on the tires, extending their lifespan.
- Tread Depth: Use the penny test to measure tire tread depth. Insert a penny into the tread. If you can see all of Lincoln’s head, the tires are worn and require rotation.
- Wear Patterns: Examine the tire’s surface for uneven wear. If tires wear more on one side, a rotation can help balance their longevity.
Keeping track of these indicators ensures your Subaru Ascent runs smoothly and safely on the road. Regular maintenance protects your investment and enhances overall driving experience.
