Can I legally mix Enviro-Safe Refrigerant with R-12 or HFC-134a?
The United Sates Environmental Agency (EPA) prohibits the mixing of certain types of refrigerant that are not already “pre-approved mixes”. Although mechanically there is no risk of incompatibility, there is legislation that prohibits such acts. (Although it will certainly work well as a replacement for either R-12 or 134a, if your car is still an R-12 unit it would first have to be defined as a 134a or other type of non-ozone-depleting unit before you could legally install it).
