Oil filter K&N or OEM Subaru

For oil i used : Motul 7100 10W-40 (4L but only 3L required.)

K&N KN-303 Filter

Ive never had a single issue using either mobil 1 or valvoline in any of the cars I've owned. K&N filters typically.

Also get a good Putolator or Subaru brand oil filter that is rated for the higher Subaru oil pressure so that it is filtering more often and not blowing open the internal filter bypass because Clean oil will make the engine last longer.

If you're vehicle manufacturer has an extended change interval then this filter will work with that. Some Porsches have 20,000 mile changes intervals and this filter is able to last that interval. Do the oil change as is recommended by your manufacturer. The K&N oil filters are killer and treat your car well.

Wait until you change the filter on a Subaru where the filter is upside down.

you can slap some new wheels on for a fresher look but obviously do this with number 2 in mind.

I have used K&N filter the entire time on my car. Owned it for almost 5 years and never had a problem.

second oil change i used 0w-30 with a KN oil filter and it felt like it had more torque off the line. It could just be a placebo effect but that's what I feel.

I changed my oil yesterday and was baffled to see how dirty my oil was at 5k miles!! Those k&n oil filters may have higher flow but mannnn do they get dirty. Do not recommend.

Those KN filters are so tiny and I have had one break in my NA Ford Falcon so I don't use them any more.
