KATSU 7L Manual Vacuum Oil Pump & Fluid Extractor Suction Pump for Cars, Motorbikes, Marine Engines

This oil extractor pump is just what I need, to change my households car engine oil.The unit is made from tough ABS plastics and sits tall and each segment with ridge equals 1 litre of oil, which is easy to see.The various nylon tubes and bung, caters for most cars dipstick tubes. The gaskets and disconnectable parts are sturdy and seal air tight. The hand pump is easy to build up pressure, and as I press the release valve, I could see my pre warmed engine oil come through. So, I basically took out 3 litres of used oil and top up with 3 litres of fresh oil via engine oil filler hole. Decanting was easy, by removing the bung and gently pouring the used oil into a container, before taking it to a recycling centre. This unit is so simple to use and saves me a lot of money on labour charges by doing my own oil and filter changes. The pump action feels good and strong.I tested the unit and it holds and then releases pressure very well.Very good value for the performance and build quality.

Extracted 6 litres of old engine oil out of 2010 BMW 1 Series 116td N47 in under 15 mins with the largest of the three interchangeable tubes that came with the pump.Prior to oil change the sump on the BMW was slightly overfilled and complete oil change was needed; the pump sucked all the oil out of the sump via the dipstick hole. The car took bang on 5 litres of new oil which measured just under the max mark on the dip stick ( manual said this make of BMW takes 5.5 litres ) so proves all oil was removed.The pump has spout and this meant old oil was easily transferred to old oil containers for eventual recycle.I got cars engine warmed up to max operating temp before the oil change - not a problem for the pump which is also great value for money and means no getting under cars with filters that can be accessed from the top of the engine.

In principle these devices are a really good idea, however, there are several issues with this product. The oil tubes are now way long enough. For most people, I would suggest a 2-meter length, not 1 meter as supplied. Secondly tube sizes. If you drive a massive SUV then maybe they will be ok. I drive a Mercedes 3-litre diesel and the oil pipes were either way too big or the one that did fit was really for use extracting coolant or water. It took ages for the oil to be sucked out due to the size of the pipe. I will have to buy a length of 2m length of flexible PVC hose to the correct size then I am sure it will be a cracking device. As for quality, it seems a robust item subject to the above. As far as quality control goes it is the usual Chinese issue, I got sent two pipes the same size rather than one of each of the sizes listed. Oh, and a top tip drive the car around the block to warm the oil. Lift the bonnet to let it cool and by the time you are all set up to go, it will be the right temp. Not too hot not too cold. Also don't forget to remove the oil filler cap so you don't create a vacuum

Thought Id try one of these as its never a bad thing changing oil in a car in between a service or if its older just doing it at home.Most modern cars these days seem to have a drain plug and an oil extractor port, its either a stand alone port like the dipstick of old or its a small tube inside the oil filler cap that both lead down to the bottom of the sump.Oil in most cars is synthetic these days and often much less viscous although still providing the same level as thicker organic.Oil it pretty cheap to buy and so is a filter (if performing and interim oil refresh, well within the miles a filter change is not really needed but if its easy to get at might as well! But it should always be replaced at least once a year or when its reached the MFR's service mileage or before)This means for a quick and simple oil swap (filter or not) you don't need a jack or to grovel under the car. You just place the hose onto the outlet and pump and it extracts the oil perfectly.Make refilling with the correct amount to avoid overfilling easy too. It shows how much has been extracted. (I used a marker pen to highlight the measurements on the side in white so it can be seen when full!Once its out you know how much you can put back in without thinking, and then top up to the suggested amount for the engine if required. bear in mind if not doing the filter there will be some stored in there and around the rest of the engine so it will always be a little down, or if its a diesel where the oil might be diluted with fuel a little more.Simple rule check the oil amount on the dipstick or car info screen if digital, then do the extracting (make sure the car has been run for 15 mins and let stand so the oil is warm and has had a chance to return to the sump. Extract however much say 5.8l If the car is supposed to hold 6 then there could still be oil in the filter or elsewhere or it could have just burned it. Top the car back up with 5.8L and let it settle (maybe run the engine for a little bit) then check the amount again and top up as required.Then you can pour the empty old oil into the 5L can you just used and if you have a spare one put the rest in that and off to the tip. Its easier to buy 5l and 2 1L cans but might be worth using and old coke bottle to dispose of any excess that wont fit in the 5L can!Its an easy to use system just a few pumps and its working. The only downside it the length of the hoses, I had to put mine on a small step/platform ladder to get it to reach and as it was still a bit taught i did have to hold the tube on the unit to stop air getting in. I could have stood it on the engine but the height makes it more tricky.Hindsight Id get some of those water houses with the push fit connectors for plumbing in fridges etc as that would mean a longer hose.Now there is no excuse for not keeping the car serviced and save a few quid from dealer prices or waiting for a slot.
