isceon 49 istead of r134a

[dp15]

Hi Guys

Does anyone know if I can use Isceon 49 instead of r134a for a car aircon system as a drop in as I have lots of it.
Or am I just being tight and should just get r134.

Regards

I cant see any problem with using Isceon49, instead of r134a. But as i see it, drop ins should only be used when there is no other way. It is not something i would do myself- Go for the right gas-R134a

Same in the long run just using the right gass makes life easier for every one.
