Still working fantastic in my 86 ford ranger with 2.9 V6. Haven't had to add any, still ice cold. Just purchased my second case. This product blends. So I have fixed my parents ac 134a, a couple old friends r12 systems. Bought more to keep on hand. This is an excellent company. Stock up.
The same company makes an 'industrial' or 'high performance' version of this refrigerant, but for some reason it requires costly HazMat shipping charges, which make it really pricey. I have used the high performance version, and it does make your system cool notably better, almost too good in one case, where the coils would ice over. I would suggest the high performance stuff in a system that is weak even when fully charged, this stuff cools about the same as the old R12 did, from what I can tell.
Each can carries a trace amount of dye, which they say can be used with a UV flashlight to aid in detecting leaks. I don't know how much dye they put in there, but I have to add 1-2 cans to my tractor every year, for the last several years, and have yet to find any dye anywhere. Either it is leaking somewhere in some blind corner, or my UV flashlight isn't strong enough, or the dye isn't all that effective. The refrigerant, however, works fine IF YOU FOLLOW THE DIRECTIONS. You use less of this, than you would R12 or R134a, so your little sight glass will not run 'clear' when at the proper charge.
There are two ways to fill to the proper charge. The first and best way is to use a two-gauge manifold and fill to the proper suction & discharge pressures, or you can use a simple shade-tree way to get it pretty darn close.
Simply run the A/C on MAX, with the fan on high, and slowly charge the system. Have a thermometer in a vent, and note the temperature. The temperature of the air coming out the duct should start dropping if the charge was low. Slowly add refrigerant until the temperature at the vent quits dropping. This signals that you have fully charged the system. Be sure to fill slowly, if you fill too fast, you risk overcharging the system before you realize the temperature has stabilized. Also, this is to be used on a system you know is low, if you are unsure if it is low or not, you should use a guage. Adding to an already full A/C system is asking for trouble.
So I contacted Enviro-Safe who tells me that this product is *NOT* an R-12 replacement.
They also tell me that Alliance Automotive is "illegally advertising" this product as an R-12 product.
This compound was originally a substitute for R-12 *NOT* a substitute for R-134(a).
Just relating my experience to date.
