Super Long Life Coolant Alternatives?

Reviews on Amazon seem positive and indicate it can be used as a substitute for Toyota's SLLC:

 

how much are you saving? hardly seems worth it.

 

You don't flush, regardless of brand. Just screws up your percent, leaves tap water in the system, and worst of all, for shade tree changers: runs ethylene glycol and the additive package into the local streams. And why go with another brand? Mixing additive packages may work out, then again it may not. Toyota strongly recommends to use their stuff, why rock the boat?

Also, I would not take this on without a thorough read through the Repair Manual. I've been doing Hondas for years, just did a Civic Hybrid a few months back. But the Prius is a little special, I'm probably just going to hand it over to the dealership, not worth the aggravation/risk.

 

Zerex Asian (Amazon) is $14.77; possibly no tax for you, and free ground shipping if you have AmazonPrime membership.
Genuine Toyota SLLC is $15.33 from AutoNation Toyota Gulf Freeway (Houston, TX); Internet Price.
$.56 difference, w/o tax. If you can't afford this, just wait till other price components require replacement.

Maybe other Toyota dealers near you will match the above Toyota dealership's online price?

That price may not be available over the counter, and I doubt you want to pay for shipping...

 

If AutoNation Toyota is close to you, just call and ask or drop in, to findout if they will give you the internet price as will-call pick-up.

I always call and ask the dealers near me, with online sites, if they can match Camelback Toyota's (Phoenix, AZ) price for the items I want. They seem to be the cheapest for most items I have looked into. Camelback charges $14.74 for one gallon of SLLC. Unfortunately, these local dealers won't price match. However, I get their online price no questions asked. Before I hang-up, I write the name of the person who I spoke to, and as him to set the parts aside, as I will be there in the next minutes or an hour. Never experienced a bait and switch yet: promised their online price, but attempted to charge full retail.

The cheapest price available to me for SLLC is 16.35.

If you get the coolant from AutoNation Toyota, consider keeping a spare inverter pump on hand. Mine went out prematurely (40,000 miles, 4yrs,7mos), assuming the dealer replaced the original pump durring the LSC (Limited Service Campaign) for the pump. I could not believe the three closest dealers near me did not keep one pump in stock.
