Buy 2 Gallons of anti-freeze concentrate and 2 Gallons of distilled water. Put one gallon of antifreeze, then one gallon of water in the radiator. Now add about half of your second gallon of antifreeze to your radiator. Then top off your radiator with second gallon of water. Now fill the half empty jug of antifreeze with the remaining water. Run the engine to mix it up. While the engine's warming up, recycle the three extra plastic bottles and put your "premixed" gallon aside for topping off the system as needed. I also write the date I mixed it on the jug, I don't know if it goes bad but after a year I figure it's toast. On hot days I top the radiator for good measure, the extra gallon lasts me about a year. Also that extra gallon has saved friends and strangers alike over the years. I keep it in the trunk of my car.
