Modern antifreeze/coolant is confusing as different vehicle makers specify different types which can't be mixed. Traditional Blue with 2 year anti-corrosion life, Red OAT with 5 year anti-corrosion life and Greens which vary on life spans. Mazda's FL22 being about top with 11 years. Pretty confusing and some makers having a real laugh with the pricing. So at last UK firm Holts have a superb product in their Prestone brand which lasts 10 years, can safely be mixed with any of the others and comes at a very reasonable price. They guarantee it to be safe for any make of vehicle. Just Brilliant. I recommend the concentrate version for a complete change as ready to use diluted is tricky since you won't get the water out of the engine, only the radiator so the mix may end up.wrong. If you know the total volume in the system then you can work out how much concentrate to put in and it will fit in the radiator. I use 1 part concentrate to 2 parts water for English weather. This is fully tested and guaranteed and much better quality and value than those from car main dealers. Very highly recommended. All Holts products work very well, I have complete confidence in them, having used them for decades!Read full review

Good anti freeze, longer life and mixes with other types. Used it in my classic cars and it is fine. Would not use in modern cars needing Pink OAT antifreeze.

Great product but packaging has lots to be desired. Container bagged but on its side. Lid loose so contents leaked into bag. Had to decant back into container before use.
