Oil changes with a pump are far more civilised.
Take car to shops to buy biscuits.
Insert pump tube down dipstick hole and pump up vacuum.
Go inside and make coffee.
Come back out and drain first 6 litres into empty containers.
Insert pump back into dipstick and pump up vacuum.
Go inside drink coffee and munch biscuits.
Go back out and remove pump, change filter and refill with oil.
Simples :)
It’s a job for large Tea buddy , not coffee ....just saying :rolleyes:

It's not that easy. The selection of biscuits is far too large these days and slows the whole job down cogitating on the choice.

Oil is a commonly used coolant for high voltage transformers and power circuits.

There was a time back in the day, when electric welders were massive oil filled metal crates, on steel wheel's and you would need to be very strong or get a helping hand to move them around.. far cry from today's inverter welders, which can be carried around in the hand, or over the shoulder like a Ladies shoulder bag....:geek::geek::geek:

I use the suction method all the time, after doing a plug change when I first got the car.. What I find about sucking out the oil is that the car has to be facing downhill and tilted so that all ( or as much as possible ) flows to the point in the sump where the dipstick goes. In my 2010 E class w212, this means jacking up the car on the passenger side, and when I do it like this...I'm getting 99+% out, and that is very near the 6.5 litres I put in to it on the last change. I will always run the car first though to heat up the oil, makes all the difference when it comes to the oil flowing out easily.

So it seems ok to extract it from the top...
But still many people believe that draining is better...
Still confused :)

Thanks to all <3

Just remember, that the important thing is to remove as much of the old oil as possible, and that it is an impossibility to remove every single milliliter,,no matter which method you use. In the dim and distant past, when engine sumps were made from steel,and the sump bolt was also made from metal, with a copper washer for a seal, and sucking the oil out was virtually unheard of, draining it was the only way to do it.....then we made mega advances in technology and plastic's and that changed everything,,,from the safe and secure metal sumps and drain studs, we went to plastic's, and the inherent problems that go with them , damaged sumps, broken plastic sump studs and nuts,,,,,,and an alternative draining method, the vacuum pump became the norm. Once you change your oil regularly, you will be fine with the vacuum method. When I got my Eclass 2 years ago, I did mt first change from the sump, that was to give me a starting point, and after that every change was done by the vacuum method.......and never a problem.

And hot engine oil is kept in a plastic container ?!

Sorry if the question is stupid, I just want a confirmation.

thanks again./

Much prefer the extraction method... after years of faffing about with ramps etc or being ripped off by garages I read some stuff on here after my s211 hit 100k miles and I decided to move away where possible and do services myself...

got a 6 litre one I think and it’s been amazing..still take cars to a garage for occasional check up and my new cls is still worth taking to be serviced...but I’ll do an inbetweeny oil change in half an hour.. gotta be worth that for fresh oil in the engine.... especially as I’m back up to 35k miles a year!

I use engine flushes every so often , I’ve done the oil change after that , by both methods . They both get all the hot oil out .

Shouldn't ever need to flush if you use good oil and intervals , LongLife oil and 6 months is supremacy , oil and filters are so cheap it would be rude not to .

A car new to me despite being serviced gets serviced again by me 2 weeks later .

If you have to flush use a detergent based and not solvent based .
