This product is actually diluted, ready mixed anti freeze and not anti-freeze concentrate, as in the item heading / description. You need to enlarge the photo to actually establish this. Maybe you need the diluted product, but this is expensive for a top up mixture. Better to buy concentrate and dilute yourself !
Carplan Blue Star Ready Mixed Antifreeze and Coolant
I ordered this item to up-fill my tank as display showed the need. I wnted a ready to use solution.I used half of the bottle following the recommendations. My car is performing better, I feel the temperature control is more responding, giving warm earlier, engine is at the right temperature after a couple of minutes. I am very pleased with this product and I would buy it again.
