Subaru Forester
Data verified by Nick Marchenko, PhD
Maintaining the proper oil levels and specifications is crucial for the longevity and performance of your Subaru Forester, which spans from 1999 to 2022 and features ten distinct engine options. Depending on the engine variant, oil capacities range from 4.2 quarts in the EJ251 to 5.5 quarts in the FB25BA. The recommended viscosity for most models is 5W-30, while the later models, particularly those with the FB25BA and FB25D engines, utilize 0W-20 oil.
In addition to oil, it's essential to monitor coolant levels, which vary by engine type. For example, the EJ255 Turbo engines require up to 8.5 quarts of coolant, while the EJ251 models need between 6.3 to 7.3 quarts. Regular oil changes not only ensure optimal engine performance but also help prevent overheating and engine wear.

What is the coolant capacity of the Subaru Forester?
The coolant capacity for the Subaru Forester varies by engine: EJ251: 6.3 qt; EJ251: 7.3 qt; EJ253: 7.3 qt; EJ255 Turbo: 7.8 qt; EJ255 Turbo: 8.5 qt; EJ255 Turbo: 7.8 qt; FA20F: 9.4 qt; FB25BA: 8.0 qt; FB25BA: 7.5 qt; FB25D: 9.0 qt. Use the coolant specification listed in the owner's manual for your engine variant.
What type of oil does the Subaru Forester use?
The Subaru Forester typically uses 5W-30 oil for most engine options, such as the EJ251 and EJ253. However, later models with the FB25BA and FB25D engines require 0W-20 oil for optimal performance.
How many quarts of oil does the Subaru Forester take?

How often should I change oil in a Subaru Forester?
It's generally recommended to change the oil every 5,000 to 7,500 miles, depending on your driving conditions and oil type. Always refer to your owner's manual for specific intervals.
What is the coolant capacity of the Subaru Forester?
Coolant capacity varies by engine. For example, the EJ251 engine requires between 6.3 to 7.3 quarts of coolant, while the FA20F engine needs 9.4 quarts. Check your specific engine type for the correct coolant volume.
Does the Subaru Forester need synthetic oil?
While synthetic oil is not mandatory, it is highly recommended for better engine protection and performance, especially in extreme temperatures. Some models, particularly the FB25BA and FB25D, benefit from synthetic oil.
What happens if I use the wrong oil viscosity in my Subaru Forester?
Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. It's crucial to stick to the recommended viscosity for your specific engine.
What is an oil life monitor and how does it work?
An oil life monitor is a system that tracks engine conditions and driving habits to estimate when an oil change is necessary. It takes into account factors like temperature, mileage, and driving style.
Can I mix synthetic and conventional oil?
While you can mix synthetic and conventional oils, it's not recommended as it can diminish the benefits of synthetic oil. If you switch to synthetic, it's best to do a complete oil change.
How do I know if my Subaru Forester has an oil leak?
Signs of an oil leak include oil spots under the vehicle, a burning oil smell, or a drop in oil levels on the dipstick. Regularly checking your oil level can help identify leaks early.
What causes excessive oil consumption?
Excessive oil consumption can be caused by worn piston rings, valve seals, or gaskets. It's essential to diagnose the issue promptly to prevent engine damage.
Should I check my oil when the engine is hot or cold?
It's best to check your oil when the engine is warm but not hot. This allows the oil to circulate and give a more accurate reading on the dipstick.
What is the difference between an oil change and a flush?
An oil change involves draining the old oil and replacing it with new oil, whereas an oil flush cleans the engine by removing sludge and deposits. Flushing is not always necessary and should be done according to manufacturer recommendations.
