I should have asked this decades ago.

What do other people use to pump the oil out of a Diesel engine prior to changing the filters and replenishing the oil.

I have used a pump, a bit like a short bicycle pump, with two tubes, one sucks the oil out the other pumps that same oil into a receptacle for disposal. The device seems designed for someone with at least 3 hands and is desperately slow (and messy) even with the oil warm. One tube is pushed down through the dip stick hole, though there is a separate hole with a rubber cap that can be used (Volvo MD2020). The discharge pipe is a bit bigger, and much shorter and pumps into whatever plastic container with a screw top I have to hand, large milk bottle.

I note the professionals use a big version that seems to have the discharge incorporated within the device. I'm sure these are expensive.

I'm looking for a cheap option, or do I have what everyone uses and there is no better.

I ask as I have 2 engines to service - and its not a task I look forward to - simply because its messy, takes so long (and I'm losing the flexibility I used to have of a young and agile monkey).

Thanks.

I do what you do. Pain in the neck, but I am too mean to buy anything else and don't have space to store it.
 

Looking at the link these look to be the sort of things that I see being used by service 'professionals'. They don't seem to use 12v powered pumps but stick with manual extraction.

Thanks



Stingy types can get chinese copies of the Pela for £20 or so on a popular internet auction site.

I've mentioned previously - being parsimonious with funds is not stingy - there seem no brownie points in spending more than is necessary - these pumps are hardly rocket science, though thinking of it - China seems to know plenty about rocket science anyway and is learning more and more and more and quickly.

I'll now check up on Chinese sourcing (and report back).

Sadly we don't enjoy access to Lidl in Down Under, only Aldi.

I love my 6L Pela. Originally bought it to service the ‘sealed for life’ gearbox in a car nearly 10 years ago and use it several times a year on all sorts of nasties (brake fluid etc.) and still going strong. It must have some valves and rubbery bits - so in my book, that’s impressive!

That said, for <£10 the 12v oil pumps on eBay etc. also seem very promising. We’ve recently transferred around 300L of diesel with one, completely ignoring the 10 minute maximum run time(!), and it did a fine job. A lot more compact than Pela! The oil would definitely needs to be warm though.
 
Change to the oil on my engines using one of the 12v pumps available on Ebay.
Comes complete with all piping including a small rigid pipe to put directly into dipstick or specific oil extraction pipe on some Volvo Pentas.
Need to move 2 x 11 litres in both engines.
Get the oil really hot for fast removal , normally go for run , it will pump warmish oil but takes longer,.
Put rigid pipe into engine and exit pipe into your waiting empty oil drum. Crocodile clips onto your battery switch on and away you go.
About 10 mins per side just keep going until no more oil comes out.
Repeat with other engine.
Better quality 12v pump about £15.00.
Cheapest 7 litre vacuum pump around £30.00 and it would have to be emptied 3 times and all that pumping.
Oil goes directly from engine to drum. No messing around emptying Pela into your oil drum.Why move it twice with twice the mess.
Why on earth people still faff around with vacuum pumps is mystery unless of course you have teeny weeny engine which only holds a litre or two.
You can also use the the 12v pump to shift diesel as well.

Forumite on here needs to shift 40 litres at a time , he does not use a vacuum pump.

My not-at-all-a-chinese-pela-copy is as happy sucking vile sludge out of the bilge as it is sucking sump oil; try that with your leccy pump.

Some of us to do allow our bilges to become filled with "vile sludge " and regard it as an affront to gin place ownership, further it should be regarded as a case for the offender to be presented with the Black Spot :):):).
Unless of course you are yachtie where different standards appear to apply.
The Pela might be acceptable if you have no battery aboard but how then do you run the 50" 4K widescreen , dishwasher etc.?
 
Do you have Lidl in Sidney?

Cheap eBay (same as Lidl) 12V pump is the way to go. Pump the oil straight into old water bottles (I use a 5 litre one for both engines) for immediate disposal. If the oil is warm takes a couple of minutes and can be used on gearbox/saildrive/diesel. The pump does not take up space when not in use like a Pela.

The cheap electric pump has a trick up it's sleeve that pela can't match, the ability to pump in new oil into very hard to get to filler holes, like a vehicle gearbox or even an outboard leg.
Just looked up the 6l pela. Why would you spend £57 on a plastic pump ?

That's a good point. I used mine for filling my Ford gearbox as access under the engine was terrible. It didn't work for the Land Rover as the gearbox oil was too thick. I could have warmed it first but access was not so bad.

I did a jimny 4x4. The gearbox filler was high on the gearbox in the tunnel.
No idea how you would ever fill it without being able to pump it in.
My boat engine has a brass oil extraction pump fitted. The cheap electric removes a litre more!

For our Jimny, and several other cars, we used a plastic hook to secure a long tube with a funnel to the top of the drivers door and lead the tube down under the car and up into the filler hole. Then pour the oil into the funnel and wait. We would now use the electric pump.
