Coolant Additive Showdown: Purple Ice Outperforms Top Competitor
We could tell you all day long about how our high performance radiator conditioner Purple Ice is better than the other coolant additives on the market, but that’s just self-promotion, and why should you take our word for it? We know what usually compels a customer to buy a product is feedback and recommendations from those they trust, and hard proof that the product is better than others. Taking that to heart, we had an Original Equipment Manufacturer (OEM) approved third-party laboratory test to see if Purple Ice outperforms the leading competitor in corrosion protection and anti-foaming capabilities.
The American Society Testing and Materials (ASTM) put Purple Ice head-to-head against the leading competitor in three industry standard engine coolant performance tests.
• ASTM D1384, Standard Test Method for Corrosion Test for Engine Coolants in Glassware
• ASTM D4340, Standard Test Method for Corrosion of Cast Aluminum Alloys in Engine Coolants Under Heat-Rejection Conditions
• ASTM D1991, Standard Test Method for Foaming Tendencies of Engine Coolants in Glassware. In each test Purple Ice passed

In the first test, Purple Ice passed where the leading competitor failed due to an unacceptably high rate of aluminum corrosion. Aluminum protection is an important test because more vehicles are rolling off the assembly line with aluminum engines, cylinder heads and radiators. Cooling system corrosion or scale build-up is a legitimate concern for vehicle owners as build-up can lead to reduced cooling efficiency or even cooling system failure. This can lead to poor performance, increased operating temperatures and potential engine failure.
While both products passed the second test, Purple Ice outperformed the leading competitor by a factor of almost four. The maximum allowed weight loss to pass the test is 1.00. Purple Ice produced a .12 weight loss and the competitor’s weight loss was .45.
Purple Ice also passed the third test. The leading competitor? Not so much. It failed due to a high amount of engine foam and it took too long to break in the permitted time. Foam in an engine coolant can cause an accelerated rate of pump impeller erosion and will result in premature water pump failure. Under some conditions, it may also reduce the coolant’s ability to properly transfer heat. Anti-foaming agent used in the leading competitor can form brown slime. This slime will coat and contaminate a cooling system and may reduce long-term cooling system efficiency.
Using the recommended coolant is enough – right?
You may be thinking, “If I already use the manufacturer’s recommended coolant in my vehicle, why do I need an additional conditioner like Purple Ice?” Your vehicle’s cooling system has its work cut out in day-to-day driving situations. Add the stress of ambient temperatures above 80 degrees, stop-and-go traffic, towing or racing applications, and your cooling system may need a little help.
Purple Ice is an easy-to-use additive and is ideal for gasoline and diesel with straight water and water/antifreeze combinations. If you’re using a mixture of water and anti-freeze, Purple Ice boosts the coolant’s heat transfer properties and protects the engine’s internals from corrosion. Using it as recommended can also lower engine temperatures and increase engine performance. We suggest adding a bottle once a year or every 30,000 miles, whichever comes first. It can also be used in racing applications where straight water is run because glycol-based antifreeze is not allowed.
