Again, its a personal decision but I have been treated well by M/B and have not felt I was being price gouged over the long haul.ġ) MB Coolant and Zerex G-05 are identical. I have found however that there is a give and take when it comes to buying O EM. The decision to buy OEM is a personal one and I agree that maintaining one’s vehicle is an extremely personal decision so far be it from me to criticize someone for their decision. Valvoline, around 2000, began producing Zerex G-05, using the BASF formula. G 05 was first used by Mercedes in the 1980’s in Europe. HOAT applications typically contain silicate. HOAT (Figure 2) - HOAT technology contains organic acids and several inorganic additives. OAT is an extended life coolant with a life expectancy of 5 years/150,000 miles. What is the difference between Hoat and oat antifreeze? YellowZerex G-05 Yellow Ready To Use Antifreeze – 1 gal. By mixing these you may lose some of the valuable benefits of HOAT. A 50% to 70% concentration range is suggested for optimum corrosion protection.Ĭan Oat and Hoat coolant be mixed? No, HOAT coolants are not compatible with OAT or NOAT coolants and should not be mixed, even if HOAT is a hybrid mix of OAT and IAT coolant.

The chart at the top right provides mixing information. When diluted 50% with water, Zerex G 05 protects modern engine components from winter freezing and summer boil over. Zerex G05 Antifreeze/Coolant is proven to maximize engine life in newer Ford, Chrysler and Mercedes-Benz cars, light trucks and heavy-duty vehicles. Provides protection for 5 years / 150,000 miles in light duty applications and 3 years / 300,000 miles in heavy duty applications. The Zerex is a slightly lighter color, but it is recommended for your JK. Yes, Zerex G-05 and Mopar Brand HOAT are both the correct coolant for your JK. Is zerex G 05 compatible with Mopar Hoat? I would not, however, mix DexCool with G-05 or G48, as the chemistry and inhibitors used are different and incompatible. The DexCool™/Prestone Extended Life™ is not HOAT, but is OAT – i.e., not hybrid, has 0 silicates. What does that mean? I’m not 100% sure, but I do know that it has a specified amount of silicates in it. This is what I can tell you about G05: it is a hybrd OAT formula. ZEREX G05 antifreeze/coolant uses the highest quality virgin ethylene glycol for freeze and boil over protection and a hybrid organic acid corrosion inhibitor package to protect your engines from liner pitting and corrosion. Zerex Antifreeze by Valvoline is the answer to universal coolants. Per the 5th printing of the 2012 Focus Owners guide: DO NOT MIX different colors or types of coolant in your vehicle. Zerex G-05 does not meet this requirement, but Ford WSS-M97B51-A1 instead which is the Motorcraft specialty gold equivalent. Made by Valvoline.Is ZEREX G-05 the same as Motorcraft gold? Whether you’re topping off your radiator or doing a complete system flush, trust Zerex G05 Antifreeze/Coolant. So radiators, water pumps and other metal cooling system parts stay clean and your antifreeze flows and functions properly. It contains nitrites that protects diesel-engine cylinder liners from cavitation, while deposit control additives guard against hardwater deposits and scale. Our low-silicate, reduced pH, phosphate-free formula with Hybrid Organic Acid Technology (HOAT) protects all cooling system metals (including aluminum) from corrosion.

Zerex is made for your car and protects better than industry standards against corrosion, leaking, deposits as well as freezing and boiling – the four main causes of cooling system failure, which is the leading cause of engine breakdown. Suitable for both gasoline and diesel engines, its original long-life chemistry is specially formulated with the highest quality virgin ethylene glycol and Hybrid Organic Acid Technology (HOAT). Zerex from Valvoline is the #1 selling OEM-approved coolant brand.
