I don't known whos to blame for this misunderstanding, if the reporters or the LTO. they show their ignorance of what they are saying. The airconditioning industries are very well ahead of this Montreal protocol specially in automotive. In the Phil, car makers use already R 134a since 1994 and yet the govt do not know that. They will not allow the 1999 model and below to be register, that's will be again a another source of corruption and big hazzle to car owners. I ageed with OTEP that the best time to switch from R12 to R134a is when your A/C is due to for maintenance or repair problem, not just because to get your car registered
