Went to change oil & filter in the wifes car (2007 Corolla-S)... What a pain in the ass it turned out to be. Oil filter was seized on good! I didn't replace it last oil change, just did the oil. Well, the son-of-a-b***h was stuck. Tried this way, tried that way, tried penetrating oil, let it cool down, etc. etc. Would not budge! And, I've spent enough dough on the GTP this month, so I'll be damned to buy another tool. Ended up pounding a screw driver through the bottom, did this twice cuz angle of first hole was bad. Smacked the screw driver with a hammer and broke the seize, then filter came right off. A little unorthodox and risky, but worked great.
