Dark green color makes it look durable unlike other watered down products. Running 3 gallons of this in my expedition no overheating seems to be a great product. Itβs even priced fairly compared to other cheap brands in stores. Only complaint is it came a day late. So Just allow one extra day for shipping youβll be happy .

Well I received the wrong product at first. I contacted the seller and was told the correct item was on it’s way and I got to keep the wrong item for my trouble. I received the correct item within a week. Good product, good service.

I’ve gotten the Diluted and Concentrated versions and both are good and have great properties as far as I can tell. I’ve done a full flush of my Ranger and filled full this this product twice and its kept the internals clean and the Engine cool in my Phoenix Arizona heat. No complaints from me.

If you have a water cooled bike it is the perfect product.

Works great for Kawasaki ninja 650. Spilled it everywhere and stank so bad. But still great
