Conventional green antifreeze formulations usually contain a number of inorganic corrosion inhibitors that provide immediate corrosion protection because they maintain the pH of the solution (buffer it), but are consumed or transformed chemically as they perform their functions. As the coolant is heated and cooled, and exposed to air, the components of the conventional antifreeze additive package are depleted over time. This causes the pH to drop, and is why the coolant should be changed out every two years or 24,000 miles.
Dexcool-type extended life coolants use organic acid technology to inhibit corrosion, and are referred to as OAT based coolants. OAT antifreezes are touted as having longer potential service life than conventional antifreezes because of the fact that the components in the additive package are not chemically consumed as they perform their function of inhibiting corrosion. The chemicals used in the OAT type formulas protect metals from corrosion by forming a thin, molecular coating on them, and because of this, are not as fast acting as conventional inorganic formulas. However, as long as the cooling system is kept sufficiently full and coolant is not lost due to leakage nor diluted by top-off with water or conventional antifreeze, it will continue to function properly. Unfortunately, if the cooling system is not properly maintained, a “red muck” is likely to form and could cause serious cooling system problems.
The third type of antifreeze on the market today is the hybrid OAT, known as HOAT (or G O-5). One of the primary problems with OAT formulations is that they are not compatible with conventional antifreezes. The chemicals used in OAT antifreeze react to some extent with some of the inorganic salts and other components in conventional antifreeze. The result of this interaction is the generation of cloudiness and precipitates. HOAT formulations are called hybrid because the additive package contains ingredients from both OAT and conventional formulas and is compatible with both.
Hybrid OAT antifreezes provide both fast acting and extended life corrosion protection, eliminate the problem of anti- freeze compatibility, and therefore are compatible with all types and colors of antifreeze.
Unfortunately, many automotive professionals consider all extended life antifreeze to be “Dexcool” and associate all the problems related to “Dexcool” with both OAT and HOAT formulas. The result of this misconception is often replacing the extended life coolant with conventional green. Industry experts say that this can be done safely if all of the green antifreeze is removed from the system. However, auto manufacturers recommend specific formulations and replacing the factory fill coolant with a different type that doesn’t meet the manufacturer’s specifications could cause liability issues down the road. A much safer solution is to replace OAT systems with HOAT coolant which meets OAT specificationsFrom recycool

OAT is not HOAT

Just got it back after 4 days because it was in the shop getting the transmission rebuilt. First thing my 4-year-old daughter did when I got home with it was insist that I put her car seat back in. How insistent was she? She got my keys and was going to do it herself if I didn't. Man, I'm going to be in trouble in a few years....
