I didn't have this problem when I changed mine last year - I have a similar "closed pan"? It looks like the white screw on cap is present in your picture. If you remove that, oil will drain in faster. Also, you can drill some additional holes to facilitate draining.
Same here - I have a large rectangular one that’s closed and it worked great. Probably because it has more surface area.
Same with my dealerships I work with. It's also all about how you treat the dealership. Some people are just straight up douche bags to the dealership even before they've gotten started. So if I'm a tech, yeah I'm not gonna give a rat's dick about your shit because you're being an asshole without cause. Before I had my first service I wanted to meet the tech who was going to work on my car, shake his hand, and say thank you. Both dealerships have done an awesome job at giving me a first rate experience such as showing me my oil and filter, my bad half shaft, and pics of my AC being replaced.
Same thing happened when I changed mine. Glad my garage floor was epoxied! One thing I did afterwards was drill a bunch of holes in the drain pan top - debating whether to try it or just get another drain pan with completely open top.
It’s never easy to trust the dealers. I’ll tell you the story about my first oil change. I am fully capable to do it myself but wanted at least the first one documented my them. During the change they managed to fling oil all over the side of my car because someone spilled oil and they drove my car through it. Then without asking me decided to wash the car. Well one of the techs must’ve used a dirty towel because they put a scratch end to end on my spoiler. Never going back there again.
That's my next purchase. If I even bother changing it again. If it weren't for the deal I got on the oil and filter it would have been much easier just to have it done.
