Prius Prime 2017 oil filter

Looks like 04152-YZZA6 for the filter.

Definitely needs a new washer, however I'd pick up a new drain plug too.

 

Repair Manual instruction attached. Seeing how your oil filter is the permanent housing style, it’ll be the “B” case, 18 ft/lb torque.

 

Yep and you'll want one of the Toyota filter wrenches for that plastic filter casing, they can be difficult to remove. (And be careful removing the old filter inside of it and putting in the new one...it's pretty easy to break those little metal parts inside that....ask me how I know!)

FWIW, a new oil drain bolt can be found on Amazon...I keep some on hand for our 9 vehicles when they need it.

Lube the O-rings during reassembly and DO NOT over tighten the drain plug. Common noob mistakes that'll cost you more time and money. Use a torque wrench - old-timers like me have calibrated hands that know, 'ball-park' how much pressure to put on those bolts and filters. Since your green and learning; best not to break things and get discouraged.

YMMV

 

I"m using a Honda oil filter socket (commonly called an "oil filter wrench", is what it is). It's heavy gauge, stamped steel, got it around 1990, more-or-less indestructible. It's compatible with Toyota, Mazda as well as Honda. Dealership parts departments may have it in stock, or can get it in.
