Oil Extractors

This raises the obvious question – why not just use the drain plug?

From what I have been reading many manufacturers recommend these for oil changes (BMW, Mercedes etc.)

They would appear to be an easy way of changing the oil, not only in engines, but gearboxes, diffs etc.

Less mess, oil drained straight into a can etc., not having to get under the car. Look like a good method for intermediate oil changes.

And it also means that garages do not have to lift the car up on ramps, and faff around removing those new fangled engine "undertray" thingies to get to the sump plug.
 
I have one for my boat engine - canny really get at the sump plug too easily .
That one on ebay looks the same as the one i have - your hands will be in agony half way through the job :eek: . It really is pretty difficult and hard going . The electric ones are the way to go but they are all pretty expensive as far as i can see .
I would much rather take the sump plug off and get any wee bits of swarf etc washed right out the way . If you have a magnetic sump plug then it's a good time to clean it off .
 
Back to my original question, has anyone used these on a Land Rover?

I would assume that this method is used for new Land Rover/Range Rovers, but wondering if anyone has used on a Series etc.

Do they suck out all of the oil on older motors?

Newer engines are probably designed to have oil sucked out of the dipstick.

Posted at the same time:)

I agree that the sump plug should be taken out, but they would be good for intermediate oil changes, say at 2,500 - 5,000 miles.
 
i have one like that and use it at work for emptying WC cisterns, pipework, tanks and sucking heating oil up it's supply pipe and it is great. I did try emptying the landy engine but it was useless. (maybe it needed lubrication). I don't think I would like to use it in the same way shown in the photo coz it leaks a good bit and if you push or pull too hard the hoses come off which ic ok if you are judt pumping water:eek: :D
Got mine at arco. http://www.arco.co.uk
 
I run a fleet of Smart cars at work (5 at the moment) they do not have a sump plug so you have to use an extractor. I have a 10L capacity, suction pump, it's like a pressure sprayer but in reverse, made by Sealey. You have to have the oil hot really otherwise it is verrrrrryyyyy slow!

Just insert the probe down the dipstick tube, a dozen pumps on the handle and leave it to it, by the time you have changed the filter the oil is all out.

There are many advantages to this method:

Cleaner
Easier
Cheaper (no ramps required)
More efficient (modern cars have a 'sump' at the bottom of the dipstick tube)
Less chance of not tightening the sump plug
Less chance of leaks
Less chance of stripping the threads on the sump

As long as the oil is warm or hot and the engine freshly run, then any sediment should be in suspension in the oil. If you are worried about sludge in the sump then the you should be changing the oil more frequently.

If you cand get it to work and be sure the thin tube os at the bottom of the sump it should work and if the oil is warm enough (thin) once the flow starts and the recepticle low enough should syphon out the old oil
 
there ok for modern cars but I still like to see a rush of warm oil splashing out of the slump plug. Have got one but with age it tends to leak, the pump seals go, by the time you mess around with it you might as well undo the slump.

I once took the slump off my series despite the oil looking clean there was about a litre of thick sludge, it was nicely molded around the pump and big ends, had to use a hammer & cold chisel to get it out

Had a car from new changed the oil as recommended yet sludge still formed in the slump, still have it, but use flushing oil every 5 oil changes. It amazes me the colour of the stuff that comes out

I think cars without a slump plug are a bad step, problems will occur in the future.:(
