So to preface, I still have jugs of ‘Yota red coolant - and to cut it correct, and according to all my upbringing - that’s D/I water when you can & are doing a correct/planned maint way. In an emergency - Hell, piss in the the thing or use local tapwater - this thread is for D/I water vendors & doing your coolant swaps on a planned schedule. I went to 2 local auto chains (Autozone & O’reillys) - and a local fabric vendor (steam irons want D/I water to keep a warranty going FYI) - zip. nada. nothing but odd looks. Premix coolant (so you’re buying their D/I H2O in jugs) - is the ‘new norm’. __________________________________________ D/I water vendor I finally found locally: Ace Hardware - sold by the gallon, $3.99 -Add your location/ZIP so others can benefit - D/I water used to be common, now IDK.
