How Often Should You Change the Oil?
For the 2.5L Non-Turbo Forester, Subaru recommends changing the oil every 6,000 miles or 6 months, whichever comes first, using 0W-20 synthetic. However, many drivers prefer to do it more frequently (e.g., every 5,000 miles) for extra engine care.

FAQs
Can I use 5W-30 instead of 0W-20 in a Subaru Forester?
Yes, you can use 5W-30 in place of 0W-20 in a Subaru Forester, especially in older engines or high-mileage situations. However, 0W-20 is the manufacturer’s recommended oil for most non-turbo Forester models due to its fuel efficiency and cold-start performance. Using 5W-30 may reduce fuel economy slightly.
What type of oil is recommended for a Subaru Forester?
Subaru recommends using full synthetic motor oil for the Forester. For non-turbo engines, 0W-20 is the standard. For turbocharged models, such as the Forester XT, 5W-30 synthetic oil is required for optimal performance and protection.

The 2014 Subaru Forester with the 2.5L non-turbo engine takes approximately 5.1 quarts of oil with a filter change. The 2.0L turbocharged Forester XT requires around 5.4 quarts with a filter.
What is the best oil for an old Subaru?
For older Subaru vehicles, especially those with higher mileage, a high-mileage full synthetic oil such as 5W-30 is often recommended. These oils contain additives that help reduce oil burn-off and seal wear, which is common in aging engines. Brands like Mobil 1, Castrol EDGE, and Royal Purple offer high-mileage versions suitable for older Subarus.
