Full oil change process on the SLK using an oil pump rather than lifting the car and releasing the sump plug.
I’d not used an oil pump before, so this was a new experience and process for me. It worked well and I’ll be using it rather than lifting the car in future.
The risk is yours if you choose to work on your car.
This is a video of what I’ve done, and is not intended to be an instructive guide.
I hope it’s useful.
