Why do subarus need so many oil changes?
Subarus are known for their reliability and longevity, but they do require more frequent oil changes compared to some other car brands. This is due to the unique design and engineering of Subaru's engines, which place higher demands on the engine oil. By understanding the reasons behind Subaru's oil change recommendations, owners can better maintain their vehicles and ensure optimal performance.
Subaru's Boxer Engine Design
Subaru's signature Boxer engine is a key factor in the need for more frequent oil changes. Unlike traditional inline or V-shaped engines, the Boxer engine has a horizontally-opposed cylinder layout. This design creates a lower center of gravity, which improves the vehicle's handling and stability. However, the Boxer engine also generates more heat and puts more stress on the engine oil. The oil in a Subaru engine must work harder to lubricate the moving parts and withstand the higher temperatures.
Increased Oil Oxidation
The higher operating temperatures in a Subaru engine lead to increased oil oxidation, a process where the oil breaks down and loses its lubricating properties over time. This can happen more quickly in Subaru engines compared to other designs. As the oil degrades, it becomes less effective at protecting the engine components, increasing the risk of wear and tear.
Subaru's Recommended Oil Change Intervals
- Subaru recommends changing the engine oil and filter every 3,000 to 5,000 miles, or every 6 months, whichever comes first.
- This is shorter than the typical 5,000 to 7,500 mile oil change interval recommended for many other car brands.
- Adhering to Subaru's oil change schedule helps ensure the engine oil maintains its lubricating properties and protects the engine from premature wear.
By following Subaru's recommended oil change intervals, owners can help extend the life of their vehicle's engine and maintain its performance over time.
Why are Subarus high maintenance?
Subaru's maintenance is unique due to its distinct powertrain design. All vehicles, except the BRZ sports coupe, come standard with all-wheel drive. Additionally, Subaru is the only automaker that exclusively uses a horizontally opposed Boxer engine in all its vehicles, setting it apart from other car brands.
How often do subarus need an oil change?
The general rule for Subaru vehicles is to get an oil change every 6,000 miles and every six months, whichever comes first. With that said, don't go more than six months without getting an oil change, no matter how much or how little you drive.
Can you go 7000 miles without an oil change?
Due to this, cars can generally go 5,000 to 7,500 miles before needing an oil change. Furthermore, if your vehicle uses synthetic oil, you can drive 10,000 or even 15,000 miles between oil changes. However, keep in mind that these numbers are just general guidelines.
Why is my car losing oil but no leak?
When a car begins to lose oil but doesn't display any visible leaks, there could be several culprits at play. Common reasons include worn piston rings, a damaged head gasket, or an accumulation of oil in the engine's air-filtration system.
How long do Subarus typically last?
The longevity of Subaru vehicles can vary based on factors such as maintenance, driving conditions, and overall care. In McKinney and surrounding areas, many Subaru owners report their cars lasting between 200,000 to 300,000 miles, or about 10 to 15 years, without major issues, particularly with regular servicing.
Why do subarus use so much oil?
Consumer Reports on Subaru Oil Consumption Issues
As a result, the new engine designs suffered restricted oil durability. Some consumer posts suggested that the piston ring design was the source of the problem. As a result, oil bypasses the piston and results in premature combustion.
Why does my car need an oil change so often?
Here's why: your motor oil deteriorates over time, which limits its ability to break down the particles that build up in the engine. Filters can only hold so much of this debris; eventually, those particles will seep into your engine.
Why do subarus always leak oil?
Another important reason for Subaru leaks is the valve cover gasket. This gasket can also become deteriorated over time, as the gasket's ability to seal the valve covers can diminish as it shrinks with age and becomes damaged.
Are Subarus known for engine problems?
Some Subaru engines, particularly the FB series engines, have been known to experience excessive oil consumption due to piston ring wear or other internal engine issues. This problem can be avoided by regularly checking oil levels and monitoring for any signs of oil leaks or burning.
At what mileage do Subarus go bad?
The longevity of Subaru vehicles can vary based on factors such as maintenance, driving conditions, and overall care. In McKinney and surrounding areas, many Subaru owners report their cars lasting between 200,000 to 300,000 miles, or about 10 to 15 years, without major issues, particularly with regular servicing.
