My "Grade 8" Oil Filter Wrench

dibbons said
The little Fram would just crush under the teeth of the chain auto parts store oil filter wrench (three times using various starting points), then still would not budge after driving a Craftsman flat blade screwdriver through its heart and hammering on the handle. Finally resorted to some high-caliber artillery, a six-inch grade 8 bolt and a yard-long persuader used for leverage. Even so, just barely got it to break free by the skin of my teeth.

Where'd you learn to use an oil filter wrench? You learned wrong. You don't grab the filter on the end. You grab it up high, right next to where it screws on, right at the threads. They will come loose every time and cannot crush right there.
