I purchased these oem fluids a couple years back from Len with the intent of getting my car up and running again but it didn't happen at that point and time. Looks like it'll be ready in the upcoming month and I was wondering if I can use these as they are still unopened.

 

It willl go bad and smell like crap. Seriouly, I don't think it will go bad.

 

The shelf life on the container would be marked if it will go bad. I doubt they will be bad if not used. You haven't heated the fluids up/used them so they should be fine.
