--------- I'll also say, if you plan on keeping R12 in your system, mark it as such. You don't want to be the guy responsible for damaging a shop's equipment because they didn't know you haven't changed over to the enviro-hippie approved stuff.

No other refrigerant is just as good as R12 that will work in an unmodified system. There are many that are "good enough" depending on the integrity of your system. But there are some that are downright dangerous, (I'm thinking highly flammable concoctions) and many are illegal.
I've been using a mixture of propane and isobutane in my vehicles for 8 years. Very cold, easy on the system.
Aside from the fact that they are illegal you guys have way more guts than I do. Everything burns if you get it hot enough, but as leaky as my systems are there is no way I would be running a mixture like that in my cars.

The combination of propane or butane and refrigerent oil when ignited has the potential to cause a lethal fire explosion. Since the A/C lines come into the cab, you could be "roasted turkey" in seconds. Also be advised if you get a fire due to the use of an illegal refrigerent, you have NO insurance. Your policy is only valid when you comply with the law ,same as if you are driving around with an expired inspection sticker. If you get into an accident that is your fault, and even if no fire results, if an investigation reveals that butane or propane is in your A/C system, you have NO insurance coverage. They will come after all of your assets and get them. Is it really worth the risk when R-134A is available and works very well? Propane, Butane, Enviro-Safe are fire bombs waiting to happen. They were meant to power gas grills and stoves, not an A/.C system.
