Adding Freon to 1995 UrS6

[Cody Forbes]

The thing here though is that these analogies don't fit this situation. It 
would be like calling gauze a band-aid. You don't call an ear wax candle a 
q-tip do you? A computer printer is not a Xerox. Sure you could call all 
different brands of R12 "freon" (I do), but R12 and R134A are completely 
different products with the only real relation between them being the end 
result. Gauze will cover a wound but it is not a band-aid.

Be careful with that Q-Tip and don't shove it too far into your ear and 
pierce your eardrum or else you may need a Band-Aid.
