Engine oil change, help please

[curly]

Hi
I am trying to do an engine oil change, the dipstick shows the oil is up to the maximum mark, I have taken the oil filter holder and the bottom screw out and removed the oil filler cap but the oil does not run out like any other car I have done, am I doing something wrong, can you help please.
This is on my Smart Fortwo 2009 Diesel Coupe 0.8 CDi RWD -- 451 799cc 33KW 45HP

That isn’t the drain plug you’ve removed. The drain is elswhere on the sump pan

There is no sump plug.

Is this on your smart?

If so you have to suck the oil out as there is no drain plug. Lidl £14 oil pumps work very well

Yes, on my Smart Fortwo 2009 Diesel Coupe 0.8 CDi RWD -- 451 799cc 33KW 45HP

I have the same car (with the 54bhp engine) no sump plug you have to suck.

I thought the oil would run out by gravity once the filter had been removed.

 

[Uncle Benz]

No, it won’t. You should have said it was a Smart. It’s not in your signature

.... and the bottom screw out and ....

I wonder which screw this is?

it was a tight one.

I have put the description in my signature now.

I have one of these, it is hard work, with no guarantee the tube is at the bottom of the sump.

 

[EmilysDad]

...., it is hard work,

Is it? ..... you poke the suction tube down the dip-stick, pump the oil extraction kit & wait

with no guarantee the tube is at the bottom of the sump.

You do .... the extraction tube stops when it hits the sump pan

You can keep pushing past the stop… don’t ask me how I know…

Took some pulling to get the end of my Pela back out, it did come but damaged the outer sheathing so ended up with a shorter pipe. I almost exclusively use the electric pump versions now.

Perhaps my extraction pump is not working properly, I pump for a very long time to find only a small dribble of oil in the bottom, I have found that the extraction tube can go into the bottom of the sump and curl back up and come back out of the oil, also the tube can get caught on a bend or a join in the dip stick tube leading you to think it has hit bottom, it is a very hap hazard hit and miss method way of trying to remove unwanted dirty and used oil, in any event there is always an amount of old manky oil left in the sump that cannot be got at, it is by far a poor way of doing an engine oil change.

I had one of those electric pumps, picture attached, , I found it as slow as the manual type I mention above and likely to drain your battery before it has done the job and only as poorly as the other type with all of its problems, you cannot beat removing a sump plug, if you have one.

you did warm the oil first?!
As for the tube curling back up ...how hard are you pushing the tube into the dip-stick tube?
I've removed a sum pan from my Smart after using my Pela extractor & there was a teaspoon full of oil left in there

I’ve 2 electric ones and both drain the oil really well. Never had an issue with speed and the benefit is no oil on the drive or all over your arm… and you can switch the pump off when your container is full. I use 2ltr plastic bottles then take them to the recycling centre. Very easy to see how much you’ve removed in 2ltr increments

As per above, did you get the oil hot first and do you move the pipe up and down to get the dregs?

 

[curly]

Yes.
I have tried various ways, I have measured the tube to correspond with the length of the dip stick, or measured from the top of the dip stick holder to the bottom of the pan on the outside but still found the tube could still be pushed past the measurements calculated so it must be curling up and back out of the oil.

I move the pipe up and down and still only get a dribble out if any sometimes, I think I must have a faulty suction pump, I did have one other thought, perhaps my pump is too big for the job, taking a long time to obtain suction in such a big area, but with a smaller pump it would not take so long to obtain suction.
