Get it checked properly. When you go SC service the next them, ask them to check where it is leaking from exactly.

If it's flywheel oil seal then you might want to delay fixing. If just valve cover gasket or oil filter gasket then it is easy fix. Get it fixed.

Now you see the difference between service at SC and outside workshop. The extra you pay at SC is worth it as they will do visual inspection and tell you if any problem.

Majority of outside workshop in MY do only what they are told. They won't tell you even if they see have oil leak. And because of the lower price they charge most people are okay with it. I personally think it is NOT OKAY. Nowadays, workshops are competitive. They need to provide value added service. Checking those things are not a lot of extra work. Heck, I am sure customers would be willing to pay a little if they do proper multi point checking like in SC.

Of course there are some workshop who does check these things. Those are rare and if you found one go service with them.
