    Official Toyota oil-change instructions for 2020 Prius Prime.

    Unlike what the official Toyota instructions say, I would never install a spin-on oil filter with a wrench. I only hand-tighten them to the specified 3/4 turns, which is sufficient. Spin-on oil filters are meant to be tightened by a specified number of turns, not by a specified torque. Installing a spin-on oil filter with a wrench and/or torquing it to a specified torque could lead to a removal nightmare in the next oil change. Therefore, simply hand-tighten it, preferably by using a shop towel or rag to protect your hand, to 3/4 turns or whatever number of turns is specified on it.

    Why does the diagram show element type filter for 2020 PRIME? They have replaced it with spin-on type since mid 2017 model on.

    The instructions have bought types. Perhaps Toyota wanted to have universal instructions for both types of oil filter, including for past model years. Since the spin-on oil filter is fairly trivial to install, they didn't include illustrations for it.

    Good find, @Gokhan! It says twice at the top that it's specifically for MY 2020 and that it's for cars starting 5/19 so it doesn't look very universal to me. o_O

    So, the torque numbers would apply for the filter illustrated, just not for the filter that's actually in a 2020. You're totally right that the spin-on filters are tightened by how far you turn them.

    Interesting that the instructions for the Gen 3 say to tighten the cartridge to 18 ft/lb and this says 13. Must be trying to fix the problems with people breaking stuff when trying to remove the cartridge cap. I think I'll download that puppy right now. :D

    Edit to add:
    After closer inspection, it does show instructions for both kinds of filters and the cartridge filters housing is still 18 ft/lb.

    LOL No find. A while ago I paid for a single-day subscription to Toyota TIS (technical information system) and downloaded most of the repair manual, which is painful because you download every subsection separately and there are thousands of them. I may share the whole maintenance section as well as a section on vehicle resetting.

    I just took a look, and the factory oil filter in the 2020 Prius Prime is Toyota 90915-10003 made in China.

    The OEM oil filter available in the US is Toyota 90915-YZZF2 made in Thailand.

    Do some years use 0W-16? I thought my 2018 used 0W-20

    Not sure of other regions, but the US 2020 model year PRIME uses 0W-16, all previous US PRIMEs use 0W-20. But they are all the same engines. The Japanese version of PRIME (Prius PHV) has been using 0W-16 since the 2017 debut.

    Once my "complimentary" oil changes are up, I'll come back to this post. :)

    Thanks @Gokhan !!! (y)
