Shoreline Marine12 Volt Oil Changer

Me llegó producto muy bien... solo algo tardado, mas de lo que esperaba pero seguro llega.

Works well. Oil must be hot for pump to work. Update: I see others are having issues with this unit but I've used the pump twice now and it pumps perfectly. It's not fast but it's a steady flow, takes about 4-5 mins to empty. Again oil must be hot for the pump to work.

This sucked 8.5 quarts of synthetic oil in 7 minutes on my 2001 Mercedes Benz C320. The stealership uses the suction method to change my oil for 140 dollars; oil and filter included. I did it for a total of 80 dollars with this unit. Everything is topside including the oil filter so I don't have to go under the car.The intake hose was slim enough to fit in the dipstick shaft and long enough to touch the bottom of the oil pan. I ran my engine for 10 minutes to get the oil warm. Warm, enough to touch. Not too hot because I didn't want to melt the hose and seals. I let the car sit for another 10 minutes so all the oil would settle at the pan. I took out the filter, unscrewed the oil cap, inserted the hoses and turned this sucker on. It did its thing. The unit vibrates along with the out take hose so I needed one hand to control the hose. The wire clips for the batteries are small but I was able to find a place to clamp at the terminals.I store this by keeping it primed with clean oil. I have an extra bottle of cheap engine oil and I ran the machine on it to flush the ugly oil out. While its sucking the clean oil, I quickly turn it off, pull out the hoses, and cap the ports making sure the clean oil stays inside the unit so that its ready and primed for next use.It does it's job. For now... I'm not sure how synthetic oils affect seals. Hopefully it still works again. I'll see in 7000k miles. Even if it were to break on me, I would still be saving money by ordering a new one.

The hoses are not very flexible to stretch straight. When I first tried it, I had a leak from the discharge connection side. When I tighten it, the hose cracked and that created more leak. But tape it with electrical tape and worked well.

works okay, not super fast. but sure makes the oil change not as messy
