...Zerex Asian is the Red equivalent, not the SLLC (Pink)....
Not in terms of being a 'Long Life' PHOAT it isn't. ZAF/WM Valv Asian Vehicle are Long Life, longer service interval AFs and like the new(er) oems come as a premix. Old Toyota Red concentrate is the older shorter service interval PHOAT (~2yrs/30k) as recommended by Toyota. Toyota says red and SLL are compatible but to get the longer service interval a complete exchange/flush must be done to SLL.
SLL premix is newer longer service interval PHOAT. 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. They are all ~5year/50k mile AFs on subsequent maintenance service. The S in SLL just means it's a longer service interval the old Red (LL).
IMO, the key to compatibility is being the same 'type' AF as vehicle spec'd. 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. No Asian vehicle recommends or uses 2eha an inhibitor in AF.
If having the Toyota name on the SLL is worth the price premium, that's an individual decision. With all the Long Life Asian PHOATs available now, it isn't for me.
