...wouldn't you? But that is what I heard right from the horse's mouth - so to speak.

There might be something to it in that those boys do know what sort of quality (or lack there of) they are selling and they do have an interest in avoiding returns and warranty claims so take it for what you will.

PAG oil plus any sort of aftermarket seal conditioner other than something specifically marketed as AC seal conditioner is probably not a good idea on a nice, new build A10.

When I suggested brake fluid I really did mean adding JUST A DROP OR TWO and then draining all of the oil out after a few days of soaking before re-oiling to spec. I went through 3 re-man R4 compressors on my old HT4100 RWD Cadillac in a year before an old-timer suggested that trick.

Hope that this helps.
