So these are factory sealed Honda DW1 ATF oil bottle. They have been on my shelf for less then 2 years, The bottles have been discolored where the fluid line is on the inside. You can see on the front bottle the discoloration line is lower towards the bottom since I used some of it. You guys ever see this on any automotive fluid containers before? Will this have a negative effect on the ATF fluid? It looks and seems good....Thanks for any input!
