The good mechanic would use (if he had to) different funnel for different fluids. But, the best is not to use funnels for the engine oils, since it’s very hard to keep them clean and you contaminate the engine oil.
For the past 20years I’m using these OilSafeSystem.com - Oil Safe Products and seperate containers for different fluids.
It’s a relief to hear that plastics in engine bay are not damaged by it. I noticed on the dipstick that it might have been slightly overfilled. He and I saw that he went a little over 4L in a 5L Castrol Edge (?) 5W-30 - it was the last bottom line and went a bit over that. He didn’t seem too worried.

I’ve been checking the engine oil when it’s warm today and after 20-30 minutes of shutting down and it’s above the max - probably about ?5mm. I’ve got a photo of it but don’t know how to post it here. This dipstick is a bit different to my other car that it’s not twisted above the max level. Don’t know if it’s that. It makes a smeared oil mark up to much above the max line with some space in the middle. I think the solid oil mark (no space in middle) is like 5mm or less above the max line. Is it something that would cause problems? That is by adding 100-200ml of extra engine oil.
