You think Subaru engineers
You think Subaru engineers put that oil filter on top for owner convience. The front part of the engine where the oil pump is in front and the bottom/front of the engine has a tuba shapped exhaust manifold that get real hot. With the (upside down) oil filter on top, regardless of the filters valve, oil still drans out of the filter when the car is parked. This leaves the engine starving for oil longer (the filter needs to fill back up) when you cold start the engine. If you buy all the BS about Subaru CVT saving gass, Subaru engineered their flawed CVT for mass production. My new normal 6 speed automatic AWD is 500 lbs heaver and the engine is 1/2L bigger then my sold Crosstreck and the MPG is the same. Subarus sold after 2008 are a joke, fake limited slip diff's and the AWD is just traction control. Dont buy the hype.
