My Honest Opinion:
Check your owner’s manual before using this in your Honda. It’s a great coolant, but the formula and color are not what Honda suggests. It’s best for older models or if you’re doing a full system flush.

This is the concentrate version of PEAK’s Asian vehicle formula. You mix it with distilled water yourself before using it.
Buying concentrate can save you some money compared to pre-mixed coolants. You get two gallons of mixed coolant from one gallon of concentrate. This is great if you need to do a full system flush.

👍 More cost-effective than pre-diluted

👍 You control the mix ratio
👍 Same great Asian vehicle formula
👍 Good for large coolant jobs
Cons:
👎 You have to mix it yourself
👎 Must use distilled water for best results
👎 Risk of mixing it wrong if you’re not careful
My Honest Opinion:
