Ester oil can be used for either R12 or R134a but it normally is used in
R134a charged systems. If you have the large red and blue knobs on the
compressor fill ports you have R134a in it.

you need to put a set of gauges on the compressor and check the pressures
to tell if you need to add R134a. If the electric clutch is cycling off and
on you still have some refrigerant in it. I converted mine over last fall
just before leaving for warmer weather.
