Would like to obtain some feedback from the forum on the life of engine oil that has never been opened. Some info that I read indicates a 5-year shelf life (storage temp/temp fluctuation plays a factor). Just looking for some input as I'm sure some Moparts members have unopened oil containers that are over 5-years old and still plan on using them, correct?

Open to feedback on all engine oil types, but specifically looking for input on full synthetic/synthetic blend oil for newer cars and oils with zinc additives for our older Mopars.


Appreciate the feedback!
