I will say the one that chewed up my forearms the most was a 1999 Mazda Protege with a 1.6 or 1.8L
The Filter was behind the engine, near the fire wall just below the large rams horn aluminum intake manifold.
There were all kinds of sharp edge brackets and hoses and harnesses around it. Absolutely abysmal.
That needed a extension and a cap wrench as well as well as some heavy turkey-tent aluminum foil to protect the hoses and components below. Terrible. Just a mess.
Another non favourite, though not nearly as bad, was my short box std. cab V6 Chevy Silverado W/T 4WD 5mt.
The filter was right above the front axle and the oil would drip and run all over the place.
So for this one I fashioned a disposable holiday turkey roasting pan to catch and channel and guide the oil to my rubbermaid drain pan. Sort of a pain to set up, but worth it to avoid a big mess.
All of these oil changes would be better accomplished on a lift, but I was rollin' shade tree on the tarmac.
