I can not beleive how GREAT this tool is. It makes oil changes a JOY, clean and easy. I have been changing oil in my cars for 35 years. I have lots of memories of laying on my back with oil running down my arm, or spilling oil out a pan or dropping the drain plug into a pan full of oil..... NO LONGER..... I am sure I am getting 99% of the oil out by going down dip stick hole.
