The real guessing game is how much oil is in he system an dhow much you should add.
Further complicated by how much oil is needed with the new style compressor.
The A6 has an oil reservoir, i think it stores about 4-5 ounces.

Measure how much oil is in the old compressor when you remove it. The aluminum compressor requires maybe 4-5 ounces less total oil in the system because it doesnt have. A reservoir, i could find any specs on how much less oil the system would need with it.

Measure oil removed with medical 5-6 ounce irrigation syringes, there pretty cheap on amazon.
