Subaru’s Blue Oil Filter Cut Open

Subaru Oil Filter

It’s been about 4,000 miles since my new motor was installed. I recently had a local shop put a RAW Performance Street Series shortblock into my 2007 STI. So far the car has been running great, and I plan on writing a blog post soon that details my recent build.

After draining the Motul 5W-40 8100 X-Cess oil that I had been running – I decided that I wanted to cut open the OEM Subaru blue oil filter. I used an electric Black & Decker saw that I had lying around, and it managed to do the trick. However, I ended up cutting the filter directly in half, as opposed to just cutting the bottom part off. (and sliding the rest out) I’ve included some high-resolution pictures below.

    Yeah, the first oil change is always riddled with small metal shavings. All of the engine components wearing in. Normally a new engine should have its oil changed early for this reason.

    Yes, very true. During break-in, the shop changed my oil a few times. I’m running Shell Rotella 5W-40 now during the winter, and might switch to Shell Rotella 15W-40 during the summer. Both of these oils were recommended to me by my engine builder. (Ron @ RAW Performance)

    At first I thought that was metal from the casing until I read the comments. Wow, that’s a lot of metal! I’ve worked on quite a few engines, but they’ve all been broken in by the time they get to me, so I don’t see this unless there are other problems.
