Sanden compressor in "72 Monte Carlo

[72MonteC]

The car had previously been converted to 134a.
My Sanden 7B10 compressor cam with 3.6 oz of PAG oil. The system with a large S6 compressor originally in the car is listed as requiring 11 oz of oil.
Is the difference of oil volume strictly due to the compressor size, or does the size of the entire system require more oil when using the Sanden compressor?
Note, evaporator, condenser, expansion valve, POA and drier have all been replaced with new items.

A few questions and comments:

Note, evaporator, condenser, expansion valve, POA and drier have all been replaced with new items.

After replacing all these components, is the system now completely "dry" (except for the Sanden compressor), or did you run the system afterwards with the old compressor? The reason for this question is given below.

I think you mean "A6," which has a rather large sump. That explains the original 11 fluid ounces of (mineral) oil specification.

If you didn't run the system after replacing all of those components, then the system is "dry." In that case, the mini Sanden 7B10 compressor would take about 6 fl. ozs. of oil, which can go into the compressor.

If you did run the system after replacing all of those components, then the 3.6 fl. ozs. of oil the compressor came with should suffice.

Thankyou, that 6oz is exactly what I was trying to find out.
