So I decided to "work on" my old pickup that has been sitting under a tree for 19 years. "This will be easy," I thought. I'll just change the oil and spark plugs, put a new battery in and go from there. So, I go down to the local auto parts store and buy a pan to catch the old oil in, some new oil and new spark plugs, a new battery, a new oil filter and an oil filter wrench. I even bought some of those cool mechanics gloves so the neighbors will think I'm an old hand at this. "I'll have this thing cranking by dinner time," I tell myself. So first things first, I remove the oil drain plug and let the old gunk stream out (making sure to get my mechanic's gloves a little dirty so they look "experienced"). Then, I put the oil wrench (you know, the standard strap-design) on the old filter and start working. The filter doesn't budge. So I work harder and eventually the old oil filter just twists on itself but still doesn't budge from the threads. Okay, no big deal, it has been sitting for almost 20 years. So I go back to the store and buy the fancier kind that hooks up to a ratchet and go back home to have another go at things. After about 30-45 minutes of maneuvering and twisting and cursing and sweating and even hammering the ratchet handle with a claw hammer to help it twist the old filter off, the filter is even more twisted but still stuck firmly in place. So I decide to bring out the big guns... I get an extremely large, flathead screwdriver from the bowels of my tool chest that has never been used (who needs a flathead screwdriver the size of a walking cane anyways?) and put the tip of it agains the oil filter and hammer it though. "This sucker is whipped now," I said out loud. Or at least some word that rhymed with sucker. Then I twisted that screwdriver and gave it my all and it ripped that filter to shreds! But the threads didn't move. So, I came on Amazon and looked around for a different type of oil filter wrench and came across this thing. "This thing looks too flimsy to do any better than the hell I just put that old filter through," I thought to myself as I clicked "Proceed to checkout." But all of the good reviews convinced me I had nothing to lose. Besides, I can just return it if it doesn't work and write a review about how all of the other reviewers were nuts for thinking this thing was "all that." It arrived in the mail the next day and I was excited to try it out, but still skeptical. I blocked my schedule for the evening because I was determined to make SOMETHING get that oil filter off, starting with this tool. I put my gloves on (which by this time had me looking like the Chief of a Nascar pit crew), told my fiancé to eat dinner without me, and headed to the garage. I laid out all of the other, failed tools beside my mechanic creeper for back up, put some Van Halen on the bluetooth to keep me motivated, then I grabbed this tool and rolled under the old Ford. I put the mouth of this tool at the base of the oil filter with the teeth gripping the stubborn oil filter like an alligator crushing a human skull and twisted...and the filter came right off. So the morale of the story is this: The right tool really does matter. And if you have a stubborn oil filter, buy this tool.
