thanks and thats is the problem.
I read specification about their coolant and free of which elements and I can’t find any in a store. Store clerk was kind of smiling and saying if you want exact same specification then you have to buy from toyota.
It is interesting Toyota coolant (even 100% coolant) is almost twice as expensive than most expensive off the shelf from a auto store. Not sure if this a way to customer confused and keep buying toyota stuff or it is has some real benefit?
