I hated the goddam oil filters. They're in that large circular part on the bottom of the oil pan. Those would seize due to extended change intervals and would be a bitch to remove. Then it would drip oil forfuckingever so you were guaranteed to get oil on you. Sometimes the oil filter itself would be varnished in place so you'd have to tear it apart to get it out all the while being dripped on. All for a customer service I didn't want to do to begin with.
