AC Oil

[Christopher Gharibo]

Thanks for the replies to the freon overcharge post. I went back to the shop
and he admitted to over charging (pressures were 60/200) and recharged with
750gms of 134a. Resulting pressures were 30/150 and the car cools very well.

What's the best way to tell that an AC system has sufficient oil? When the car
is recharged with one of those AC machines is oiling part of the recharge
automatically?

Thanks again,
Chris
