Parts for your 2007 Subaru Forester-Oil filter

2007 Subaru Forester oil filter — what it does and when to change it

Based on the Subaru Owner’s Manual for MY2007 Forester and the Subaru Factory Service Manual for 2006–2008 Forester (SG series, Lubrication section), the 2007 Subaru Forester is fitted with a replaceable, spin‑on engine oil filter for its 2.5‑litre EJ engine. So yes, an oil filter is absolutely relevant and used on this model.

This oil filter is there to trap the fine metal particles, combustion by‑products, and everyday grime that circulate in engine oil. By keeping the oil clean, it helps maintain oil pressure, reduces wear on bearings and cam surfaces, and protects the boxer engine during cold starts and hard driving. Without a healthy filter, dirty oil can thicken, pressure can drop, and the engine can cop unnecessary wear long before its time.

For servicing in Australian and New Zealand conditions, it’s sensible to replace the oil filter at every oil change. Many workshops follow an interval of about 10,000–12,500 kilometres or 6 months, whichever comes first. If the Forester sees lots of short trips, dusty roads, towing, or frequent cold starts, shortening that interval (for example to 7,500 km) is a smart move. These recommendations align with the maintenance guidance in Subaru’s owner and service manuals for this era.

When fitting a new filter, the gasket should be lightly oiled, then the filter installed hand‑tight only (typically around three‑quarters of a turn after the gasket first contacts the housing). After start‑up, check for leaks and confirm a steady oil pressure light extinguishes promptly. It’s also good practice to replace the sump plug crush washer during the same service and recycle the used oil and filter responsibly.

• Use a quality filter that meets or exceeds Subaru specifications.
• Always change the filter with the oil, don’t mix a fresh fill with a clogged old filter.
• If the old filter’s gasket sticks to the block, remove it before fitting the new one.
• Keep records of kilometres and dates to stay on top of service timing.

Treated right, the Forester’s oiling system stays clean, pressure stays strong, and the EJ engine rewards the driver with smooth, reliable running for years.

Popular questions about 2007 Subaru Forester oil filters

How often should the oil filter be changed on a 2007 Forester?
Most owners and workshops in Australia and New Zealand replace the filter with every oil change, commonly every 10,000–12,500 km or 6 months. For heavy use—short trips, towing, dusty tracks—shorten the interval for extra protection.

What type of oil filter does the 2007 Forester use?
It uses a spin‑on canister‑style filter designed for the EJ‑series 2.5‑litre boxer engine. Choose a reputable brand that meets Subaru’s specifications or an equivalent OEM‑grade part for proper filtration and fitment.

Where is the oil filter located on a 2007 Forester?
On the EJ25 engine, the oil filter is mounted on the lower front side of the engine. It’s accessible from underneath with the vehicle safely supported, a drain pan and filter wrench make the job straightforward.
