Oil change pump @ Lidl

What would your solution be for changing the oil on a engine without a sump plug? An actual solution, not some fascile comment about not buying one in the first place.
On a car designed for oil extraction in this way, no worries crack on with a pump. I'd just be worried on an older car not designed for this that you aren't getting as much oil as possible out, and its not dragging stuff off the bottom of the sump with it.
If theres no sump plug I'd be tempted to remove the sump after say.... 80k miles, clean it out and carry on.
In fact I'd probably remove the sump during a n oil change on a high mileage purchase anyway, just to see if anything is there out of pure curiosity..... maybe I'm strange like that.

Some of the Pela pumps are not suitable for petrol as it damages the seals
I've been using a Pela for years
Me too. The amount of oil left varies with the car, on my old Civic and wife's Ocatvia there was virtually nothing left in the sump, on her Hyundai Coupe there was probably 300ml left when I tried it, so I always used the sump plug.I've been using a Pela for years

Just get a pelo pump simple and easy.
I have a 6 litre Pela pump and it's a great tool for emptying the likes of the header tank (to top up with more coolant) and doing the likes of power steering fluid changes and in my case, was worth it's weight for the rear diff, Haldex and TXB fluids but to try and use it to drain 6 litres of oil out the sump... Jesus, you'd be there for days so I just use the tried and tested sump plug method for that. For putting fluids back in, I bought a small hand pump on eBay, a fiver or something like that and can be used to draw fluids out and also push them back in and it did the job very well...
Always a bit dubious about the pump out engine oil change methods...

Now you’re talking! Just ordered one - its ideal for pulling fresh petrol through after draining stale stuff. Still wouldn’t use it for oil though.

I have never had an engine without a sump plug, didn't know they existed beyond probably some far east toy engines presumably?
None of the older Smart ForTwo/Roadsters had a sump plug, and a large number of marine engines don't have an accessible sump plug when installed in a boat.Davie said:

5.5 liters in about 30 minutes, I just leave it. There is a knack but you can see if it is not sucking, quick fiddle, works a treat. Never more than an hour. ^^ It's all situation dependent.
I can see a pump failing to do a thorough job if you have a dip tube which has a few bends in it which a semi rigid pipe won't go down.
If you use a really flexible pipe how do you know when it's hit the bottom? Well you don't. It could go down, exit the dip tube and curl around. It could hit the sump pan and curl around.
You've got some problems there getting a flexible tube (which looks like the one we are discussing) to hit the bottom and stop, I would have far more confidence in a semi rigid tube.

True removing a sump plug is easy
Jacking the car up, putting it on axle stands, removing at least 20x10mm bolts some of which are corroded and snap, removing the undertray, getting the drain tray in the correct place and trying to avoid either getting an arm covered in oil or dropping the sump plug is less so

I would have thought it was quite good sending the new apprentice to drain the oil out of the inboard boat engine. 
Parents had a 40ft moonraker with two giant 175 perkins diesels. I used to get down in the crawl space to service them including oil changes from conventional sump plugs. I remember it used to get hot down there, and if you spilt anything you would be tasked with cleaning out the bilge.liner33 said:

If that's all too hard for you you shouldn't be changing the oil to start with.

Will there ever be a thread on Piston Heads where people agree to differ ?
We all have opinions and preferences so why can't we accept that ?
Each method will have it's pros and it's cons and each of us will weigh them up and possibly arrive at a different result.
I might well change my mind if I owned a car with "20 x M10 bolts" holding an under tray in position, but I've never seen one yet.
That's more fixings than holds the gearbox to the engine, or the clutch to the flywheel on most cars.

Autocorrect fail that should be 20x10mm bolts , but Jaguar did see fit to use that many , i guess they want to stay on at 180mph, plus they designed it to change the oil without needing to remove it so it doesn't matter That's more fixings than holds the gearbox to the engine, or the clutch to the flywheel on most cars.

Many people are resistant to change and progress and take comfort in outdated ideas
