Any bottle that is vented is going to spray oil on your truck. The oil is a mist and the vents let it out. Do not try a non vented bottle, you will have some serious troubles if you do. The vents are mandatory. I extended the hose down to the front axle and tied it off at the drivers shock mount. I have no more oil on the truck at all, but it does spot the driveway. It will let one drop hit the driveway every time I park it. I did my truck and one for another member for a whopping total of less than 5 bucks. Get some 3/4" hose, a 3/4 barb-barb coupling and 2 stainless clamps. Tie it off at the axle or trackbar and you are done with oil on the truck. Simple Green will take the spots off the driveway pretty well. Hope this helps.
