Getting your vehicle's oil changed at your local shop is a real pain. You have to wait forever and then you're handed an outrageous bill. Now you can easily change oil yourself without crawling under your vehicle, fighting with the oil pan plug and messy spills all over the driveway. Just connect this 12V pump to the terminals of your vehicle's battery, insert the 6mm (outer diameter) tube into the dipstick bore and old oil is neatly pumped out in seconds. It's perfect for use with most vehicles and is a must have if you own a newer vehicle where you can't easily reach the oil pan. This is a customer return. Customer returned items have a 7 day return policy.
