The number 32 looks like a 32cSt oil.
SUNISO 3 GS or RENISO KM 32 or Emkarate RL 32H or Zerol 32 should do the job.
Hello nabil you need ISO VISCOSITY GRADE 68 or above ester oil for screw compressors to run
You will do best to check the IOM for the unit and see what oil or alternate oils are approved by the vendor for use in the compressor. Most are using a semi-snythetic on R-22. For normal A/C duty, Iso 68 is the viscosity used for the screws. For lower or higher temps, they may require a different oil.

What's the te/tc?
te is evaporator temperature, I use ET
tc is condensing temperature, I use CT
