Cup, chain, strap or claw — the housing decides, not you · review
A two-arm self-adjusting wrench on a 1/2 inch drive: it tightens its grip as it turns, and it works from a ratchet rather than by hand.
The last word The one that works from a ratchet. That is often the difference between reachable and not.
A two-arm self-adjusting oil filter wrench for 60 to 80 mm (2.36 to 3.15 in) filters, driven from a 1/2 inch square.
Every other wrench here is worked by hand. This one accepts a ratchet, an extension and a universal joint — which means it can reach a filter that is visible and not touchable, and that describes a lot of modern engine bays.
They close as the tool turns. The practical effect is that it does not need to be set precisely, and it does not let go halfway.
60 to 80 mm (2.36 to 3.15 in). Measure the filter on your car — it is written on the side of the one you are replacing, or in the parts catalog.

Because it lets you use an extension. A filter above a subframe can often be reached with a ratchet, a long extension and a wrench on the end, where no hand-held tool fits at all.
The two jaws are geared so that turning the tool pulls them inwards. It grips harder under load rather than slipping, which is the failure mode of a fixed-width wrench.
At $16, it is the 3 cheapest of the 4 models in this category published here.
