I was hoping to use this unit on my GMC diesel to make pil changes even easier and cleaner. Unfortunately I couldn't get the tube down to my oil basin. I believe there is something in my trucks oil system design that wouldnt allow this. I will still say that this is angreat product. I then used it to drain the reservoirs for my boat's porta bracket hydraulic system. It worked perfect! Great idea. You may want to somehow check with the company or a mechanic to see if this product is functional for your specific application. Luckily I have many uses for it and am very happy with my purchase.
