Long life ok with Super long life antifreeze?

NO! Use only the antifreeze specified for the Prius.

Topping off with water is better than introducing a non-compatible anti-freeze.

I'd use nothing else.

 

I agree with Mike think you need to stick 100% with the good stuff if at all possible.

 

Prestone extended life antifreeze says it's compatible with all types of antifreeze. What does Toyota require?

If it's PINK,I'd use it..........

Your car.......you are FREE to take the risk.

The coolant runs through the inverter, has a specific PH and dielectric characteristics.\

Weigh the savings, if any, against the cost of a new inverter.

Also, if Toyota analyzes the antifreeze and finds foreign or non-conforming molecules in it, it might void any warranty claim, original or extended.

Using it might not do anything. Do you feel lucky, today?

 

This coolant meets Toyota specs at walmart online; Valvoline Asian Vehicle Formula Antifreeze 871668 was $8.38 a few days ago now $11.97.
I'm new...says I can't post links yet.

People,

These alternate coolants are fine for Toyota non-hybrid cars. They are probably also fine for the Engine coolant loop in Toyota's Hybrid cars. They have not been tested or certified for use in the Inverter loop so use them at your own risk. I will stick to the Toyota SSL coolant in my 2016 Prius as I did in my 2004 Prius for 288k miles with no coolant related issues.

I was just helping out with the link/
imho not worth to take a chance with non-toyota coolant//

 

You get what you pay for. I recommend the Toyota SLLC that is called for in the owners manual. To use any thing else is each individuals risk and choice.

 

Toyota SLLC (00272-SLLC2), $15.16 at Camelback. 2007 Toyota Prius Parts - Camelback Toyota Parts - Genuine OEM Parts - Free Shipping

You should be able to goto your local Toyota Parts department and ask them to match. Depending on the parts manager, he will come down from their full retail, arm & leg price, which is far greater than $20. The parts manager had no problem letting me have a gallon for $16.24 + tax. This wasn't as low as Camelbacks, but far cheaper than full retail price.

Amazon has the Zerek Asian formulation for $14.06. Link

So, are you that cheap not to go OEM fluid for an additional $2.18?

 

I just checked my bill, it was $19.14 Canadian. This was from a local dealership parts department, doesn't say anything about discounted.

So not too bad, doesn't hurt to ask. This is something you get so infrequently too.

 

According to one study, Toyota Prius is the least expensive car to maintain. It's the cheapest there is! So why cut a corner?

Oh, and the coolant for the engine DOES NOT "run through the inverter". That's a completely separate system. But I'd still use the correct Toyota specified stuff. A jug will last you a lifetime, unless you use it to change your own coolant.
