Sealey TP69 6.5L Manual Vacuum Oil and Fluid Extractor Pump - Perfect for Car Maintenance, Motorcycle Oil Change & DIY Automotive Fluid Extraction

This is an excellent piece of kit. For car engine oil changes I have always removed the sump drain plug. With this kit I was able to remove almost all the old oil from the sump. To check how much was old oil was still in the sump I removed the plug and drained less than 0.5 litres (may be even less than 0.25l). So it does work very well and what's even better is that you can leave it pumping automatically and come back to find its all done!I will be using this for all future oil changes. If I buy a new car I will do the same test to see how much oil it leaves in the sump as different makes of car can have odd shaped sumps leaving more or less oil in the sump. Anything less than 0.5 litres is a win in my book.
