I bought an oil collection product from one of my cars. The product failed miserably in its one job. The bottom of the mat dissolved in oil and turned into some kind of king of black goo. Pieces of it are now strewn all over the garage floor and look awful. Updated 10/27/19. The coating on the back of the mats was completely destroyed, rubber sludge was all over the garage floor. I spent 10 minutes scraping it off and then threw out both rugs. Avoid at all costs. Terrible product.
