A common additive is demineralized water and is part of a 50/50 mix.

With all the Long Life Asian PHOATs available now, it isn't for me.Welcome to the Thomas guide to the best antifreeze 2023. If having the Toyota name on the SLL is worth the price premium, that's an individual decision. No Asian vehicle recommends or uses 2eha an inhibitor in AF. With the exception of the WM Super Tech mentioned which is a universal DexClone with 2eha, all those mentioned in this thread are Asian PHOAT AFs. IMO, the key to compatibility is being the same 'type' AF as vehicle spec'd. The S in SLL just means it's a longer service interval the old Red (LL). They are all ~5year/50k mile AFs on subsequent maintenance service. As is ZAF/(WM VAV) which in addition to coming in red(ish)/pink tint now also comes in blue tint to match Honda Type 2, Subaru and Nissan Long Life AF tint. SLL premix is newer longer service interval PHOAT. Toyota says red and SLL are compatible but to get the longer service interval a complete exchange/flush must be done to SLL. Old Toyota Red concentrate is the older shorter service interval PHOAT (~2yrs/30k) as recommended by Toyota. ZAF/WM Valv Asian Vehicle are Long Life, longer service interval AFs and like the new(er) oems come as a premix. Not in terms of being a 'Long Life' PHOAT it isn't. Zerex Asian is the Red equivalent, not the SLLC (Pink).
