Where does everyone take their used Redline trans fluid (the pink stuff} for recycle. It does not quite look like any kind of oil that your local parts store might take. Thanks.

 

I take all my oils to the local disposal people. Oil is oil, being red doesn't change anything!

 

Exactly. I have to turn in a lot of oil in my line of work, and SafetyKleen, ThermoFluids, etc does not care what color the synthetic oil is. The drums we turn in are mixed with anything from 10w30 conventional motor oil, to synthetic ATF and 75w140 gear oil. All the same to them.
For instance, ATF is certainly red, and they will take that without issue.

If your local auto parts store advertises that they recycle used oil, just turn it in to them.
