Official (OEM) Toyota Prius 2016 (Gen 4) oil-change instructions

Exactly.

Edit 1: Search for 0W-20, replace with 0W-16.
Edit 2: Search for 5W-20, replace with 0W-20.

I'm not from Missouri, but I'm sceptical, lol. Specifically: that there anything other than the revised oil spec going on, that the engine blueprints have actually changed.

There were some contradictions, somewhere. Likely due to incomplete edit. Can't find them at the moment.

But be that as it may: yeah, that last question, in spades.

Remember these are the guys that also say:

"...the vast majority of vehicles will not experience this condition..." (regarding 3rd gen EGR clogging)

 

I see the confusion. Inconsistency in the 2018 manual, which does not appear in the 2019 manual.

 

And is this known to not be the case?

 

I think so. Anyone here (priuschat) with over 100k miles that checks, finds a lot of carbon. @mjoo did some flow tests.

 

Oil cap says 0w-16 on 2019 Prius awde xle.

 

Could that be THE engine mod?

 

TIL there is such a thing as 0W-16 oil.

 

I should ask at our dealership. I was just in there getting bulk 0W20. I'm betting they've yet to hear of 0W16.

Edit: Ahh, TIL means "Today I Learned". I thought at first you meant 'till, lol.

 

0W16 is also used in the current Corolla Hybrid in Europe.

 

Since the search for this forum isn't so great, trying to search for something for a specific generation gives results for the entire forum...

I just wanted to put on the interwebs that my 2018 Prius 3, manufactured October 2018 in Japan, (sold in Southern California) has the spin-on filter 90915-YZZF2.

Apparently, word on those "match your part" sites (used by Amazon, AutoZone, etc.) spin-ons were only compatible with November 2018 and beyond.

 

I believe my 2011 and 2012 had a canaster. 2015 and 2016 had a spin on as well as my 2019.

As far as oil is concerned, they probably did the 0W16 to get a few more MPGs on the Federal EPA test. 0W16 is too thin for hot climates in my opinion only and does not reflect the views of the management.

 

My son's 2015 Prius v and my 2017 Prius trim 2 are both canister type.I think the spin-ons started in 2018.

 

That may or may not apply to the Gen 4 Prius
Perhaps you should also post in the Prime (Gen 2 Plugin) forum.

 

@Gokhan 's posting looks to be valid for fourth gen Prius or Prime, shows both oil filter styles, though Toyota's language is absurdly stillted. Portrayal also is hopeless, they show no image of the spin-on, ton's on the permanent housing style (which they're no longer using).

Note the 13 foot pound torque value, that's the spin-on torque. And/or 3/4 turn past first contact. Either method of tightening will do. And then the 18 foot pound value further down, that's the permanent housing spec.

 

I've converted my 3rd gen to spin-on, and at first install I put a silver sharpie mark at 6 o'clock (at first contact), then torqued to 13 foot pounds. And surprise surprise, the sharpie mark ended up around 3 o'clock (3/4 turn).

The term "by hand" I wouldn't take literally, I get the sense a more accurate description would be "without torque wrench". I doubt I've got the grip and strength to do 3/4 turn by hand.

 

Curious why you converted to the spin-on. Isn't replacing just the filter element as opposed to a whole filter assembly (which I understand to be the spin-on) more environmentally friendly?
