Use the stuff for termite protection... pour it on your fence posts.
Its terrific and cheaper than creosote..fence posts I doused 30 plus years ago are still rot and insect free...The fence my dad put up at our house in 1960 had all the fence posts done over the next 5 or 6 years by my brother and myself...lots of cars and lots of oil changes --the posts are nearly all still rock solid and we replaced just the palings and the rails about 10 years ago..
