Engine oil ddi not come out

[hans_fh]

Sorry for my poor English since my first language is German

Last Friday, I changed the engine oil myself. Before I changed the oil, I drove the car for ten minutes at 40 MPH to get it warm up.

Then, I take the filter away and wait for the oil come out.

However, only a little oil came out and no more....

I had been waiting for 10 minutes but the oil did not come out.

I had no idea what was going on. So that I had to start the engine and then all the oil came out. I turned off the engine when I thought all the oil came out.

I know it is bad for the engine, but I am curious why the oil did not come out...

I use MOBIL 1 Synthetic.

Thanks a lot!
