HI, I bought a Silverline Oil Extractor Pump to be able to change the oil without getting under the car. However my plan failed since I was only able to extract half the oil, even using a thinner pipe. It seems I was unable to reach the bottom of the sump.
Is this how these pumps are supposed to work or should it be a tight fit to create a vacuum to be able to extract the oil from the bottom?
Anyone has experience using these pumps, on a 1.6tdci maybe?
