https://www.reference.com/vehicles/motor-oils-shelf-life-e4589115d4577487I wanted to drill down to what is exactly the shelf life of multi grade oil. The above URL explains a lot of it and it really is nice to know for some of us who rush out to buy oil only to come home and then keep it on a shelf for 4 years. The OP did say he was going to keep it from Spring to Fall which is like 6 months. Hey no worries. How the conversation turned to permeation and absorption still boggles the mind. But yeah, it has a shelf life.
