    So I went ahead to do an oil change yesterday and for the life of me couldn't get the oil filter off. The oil filter wrench spanner top snapped off, also believe I took one of the housings plastic fins as well...

    My mistake for using a cheaper tool, I didn't realise that the internal removal wrench was welded on (visible welds) rather than being one unit like others.

    Also is it just me or does the oil filter housing angle seem a bit "bent" slightly diagonally by default?

    This opened up a whole new research avenue into conversion kit/aluminium housing but I think I'll just stick to the original but with a good quality wrench.

    Any recommendations for a oil filter wrench tool?

    Also what are the chances of loosing 1 fin causing a removal issue be?

    I've had to use a pair of slip joint pliers the big kind no like 16 inches long or something on a few that were deformed changed a few this way no issues ever . Never destroyed . You can take the oil filter jig off a Corolla w 2z engine relatively inexpensive. I think it takes 4967 rounds

    Honda makes an oil filter socket that’s heavy stamped steel, very durable, and a perfect fit. I’ve had one since the early ‘90’s, used it on Hondas (obviously), my 2010 Prius, and a Mazda as well. Here’s a North American dealership link, Amazon has as well, any Honda dealership parts department, and you can search the part no:

    Genuine Honda Oil Filter Wrench (65mm) - 07AAA-PLCA100

    Presumably the first oil change for you? The last person probably used an impact, torque spec is 18 ft/lb.
    I finally got fed up enough with the permanent housing style, did the conversion. No regrets.

    see my signature for oil change and filter conversion links. (On a phone turn it landscape to see signatures)

    Machined steel filter cap wrenches are available on-line, and much stronger than the cheap stamped-steel and aluminum kinds. Ones that engage the "fins" on the plastic housing are a bad idea, as you proved.

    They get screwed because certain people over tighten them.
    They don't need to be super tight. I use a 6 inch ratchet to snug it once it stops.
    Just enough to almost engage the little clip on the side fin.

    Using quality tools is always the BEST thing to do.

    My second oil change, I didn't overtighten the filter to my knowledge but the removal tool had always been a "weird" fit? Either my fault or cheap tool fault will be able to tell once I get a good quality one!

    Is that oil filter socket you linked compatible as it doesn't have those groves for the fins to "engage"?

    Unfortunately based in the UK and can't seem to find it available here without paying quite a bit to have it shipped over (if they even would).

    So the ones that just fit over the top without fin engagement are fine to use?

    Indeed should of learned this lesson long ago, but having only dealt with spin-on filter types before owning this Prius never thought a "generic" tool would be an issue! Never had any issues with a spin-on installation and removal. Easy to install by hand tight and then remove with whatever tool you want!

    It’s a perfect fit, heavy-gauge, stamped-steel. Never any problems.

    Extra deep sockets with slots to match certain permanent housing stiffeners seem pointless to me, just make them proprietary.

    I’d recommend use of a medium or light duty torque wrench (3/8” or 1/4” drive). Torque for the permanent housing is 18 (ft/lb) and 13 for the spin-on conversion (which I’ve done).

    I agree with Mendel.

    Over the past 13 years, I've tried and used more than 10 different wrench sockets.

    The only one I kept and use is the Honda one. The others; I gave away.

    I did the spin on conversion, too.

    The Honda one works with the spin-on wrench, too.

    KlickWrench is available on Amazon.

    If you put a thin film of oil on the canister o-ring before re-install; those housings don't stick. You'll have an easier time removing them next time around. Properly torquing them down or just hand-tightening without any tools also works.

    Good Luck
