Hello, folks. I'm familiar with the Toyota & Lexus cartridge oil filter setup and how difficult they are to loosen, but our 2016 RX 350 has an additional element I haven't seen before. In the picture below, it's the metal tab or stop that you see at about the 11 o'clock position. What does that tab do? It looks like it would interfere with an oil change by keeping the cartridge canister from being removed all the way. This vehicle is new to us, so I'm approaching my first oil change on this one.
