Zinc oil supplement

In my county, we just place a 1 gal just labeled "oil" beside the weekly trash bin pickup. Beats going to Autozone and dealing with their fuss like "tank is full" or "your oil is too ugly". I hope the county at least recycles the plastic since many uses like outdoor deck planks which command high prices. But I too have read that much just ends up in the landfill with no sorting. My area isn't nice about e-waste, requiring hauling it to out of the way places. They should run a once per year pickup at the curb.
