Monograde mineral-based engine oil will be rancid after the time it must have been in the tins and everyone uses semi or fully synthetic oil these days, multigrades only, so unless someone wants that stuff for kitting up a film set where they need a period garage scene, best thing to do is take it to the local recycling plant where - if they echo the function of ours - they'll promise to dispose of it in best tree hugging fashion and as soon as you leave, pour it into their office stove to keep them warm.
