I have about 41K miles on my truck, had a drain and fill done at dealer about 13K miles ago.. Did the trans by-pass a month ago and I took a sample of the oil and sent it out to make sure there was no Glycol what so ever mixed in.. Test came out "negative from wet chemistry"! :D
It showed the Nissan Oil was normal.. Heres the rest of the results maybe some of you can chime in cause it's all Greek to me.
