We all understand that oil filters have to spill oil when we loosen them. I accept that. But some engineer at Mazda put conscious effort into causing the removal of the oil filter on their 2.0L engine to be a pain in the ass by hiding it above an aero sheild and making you reach up through a hole that isn’t even under the filter, thereby assuring that crankcase oil will run down the arm of the mechanic — or in my case, the poser — who is changing the oil. They probably all voted for Donald Trump.
