Funny my 88 Aries specs 3k OCIs, but change the filter "every other" oil change......and this is an easy one to change too....right in the open, on the side of the engine.....pop the hood and it's sitting right in front of you hehe.
Pain in the butt taking it off though, cause it dribbles all down the chassis, that's the worst part really.....so gotta spray down the engine/filter area afterwards.....
