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

Hi

Any advice about the oil change for 70km prius 2017, would you prefer liqui moly or totachi? As here most of the prius owners recommend to use totachi, but no one clarify the reason other than that totachi is not reiterated, while lqui moly is reiterated oil.

Noting that winter here is not so cold and maximum 35 degree in summer.

I got confused, any advice please

Thank you

 

Yes 0-20 is the recommended, but which brand, liqui moly or totachi, and what is the difference between them, why most of the prius owners recommend totachi??

I've never used either but used just about everything else, even Amsoil. The difference in synthetics in Mobile One, Valvoline, Quaker State, etc. is negligible for normal cars (IMHO)....the only major differences are seen in extreme use like in racing engines running at a bazillion RPMs.
The important thing with oil changes is to do it faithfully and often...procrastinators who go way too long between oil changes come to regret it, almost always.

 

I have a 2017 Prius Touring 4. I changed the oil the other day, and my slotted 64mm was way too large. The smaller generic multi sided wrench did fit however.

Does anyone know the size and where I can order the correct sized slotted wrench to fit my Prius.

Thanks.

 

I’m sceptical of the efficacy/need for a slotted wrench, and suspect if you measure inside face-to-face dimension of yours it would come in at 65 mm or more.

FWIW I use a Honda filter wrench, heavy stamped steel, and aforementioned measurement just over 64 mm. Works well, a snug fit. They’re available through Amazon and I’m sure through any Honda dealership parts department.


(part no out-of-date)

 

I've owned a Scion and Yota's and all take a 14mm drain plug wrench but there are two different sizes of canister oil filters.

If you want to turn a 30-minute oil change job into a few hours, accidentally pop out the metal spring and bracket from inside of the canister when replacing the paper filter! (Yes, it's replaceable but a bit tricky!)
