Thymeclock - The Royal Purple line was supposed to be snarkey not serious, guess it came off wrong. RP is the crap all the racers love and over priced as hell. But I find it super funny that its still cheaper than the GM fluid from the dealer.

As for rating, is it still possible to get anything that doesn't meet Dex3?

I had NO idea that much fluid was left in the transaxle after a change, that's nuts! Guess I'll start doing cycles of change, drive, and re-change. Ran the numbers though and with a total capacity (had to look it up) of 5.9qt, even if your getting half the fluid each time, and a perfect mixture of old an new fluid, it would take 10 drain, mix and refill cycles before you have less than a tsp of old fluid left.
