I just coated my trailer with old oil.
Using a brush, no spilling or sloppy dripping.
My vehicles use oil to the end of it's beneficial use {along with wix filters} of 7500 miles then, I use it some more.
But for my snow maintenance equipment, I use FF.
recycled used oil probably touches your life every day without you even knowing it. As consumers, we all benefit from recycling used motor oil. From augmenting our oil supplies and helping to generate heat, to protecting the environment, recycling oil just makes good sense....no dumping!
