R-134A Oil Charge - Yep another A/C?

[86-300sdl]

My A/C had not been charged / serviced for seven years until last fall when I put in 1 ½ cans of R-134a (12oz) till the pressure on the charge line looked good. Big improvement in cold air. What I did not do was add any oil.

Wondering if I should add a can (2oz) of this stuff (photo) Says it is compatible with all R-134a air conditioning systems (mine is converted to R-134a) including mineral / ester / & PAFG oils

Not aware of any leaks etc, etc. Systems seems fine. Just want to make sure it is lubed ok.

My thought if over the seven years between service I needed to add more R-134A maybe I also needed to supplement the oil.

Thanks
