Technical Chemical Ester Oil, 32 oz. (6710)

Working on the A/C on my 87 Porsche and was changing from R-12 to R-134A needed oil for the system and you must use ester oil to be compatible unless you change out the compressor and totally clean all lines including condenser and evaporator, R12 used ester oil, and R-134A uses PAG oil but you can use ester with the R-134A, but PAG is not compatible with R-12 nor is it compatible with ester oil. So long story short wanted to stay cool and this supplier had the best price and received it a day before expected, Very satisfied and it is a name brand oil.

Works as advertised.
