Check oil on a cold engine (at least wait 0.5 hours after turning off engine).
Even though theoretically oil level just above L is OK, it is not so good as your oil level may come down between oil change and get below L. You do not want it. Normally it should be somewhere between middle and H after oil change. Above H is also not good, as stated in the above post. Also it may accelerate oil leaks through seals.
There is one sure way to have it done right: do it yourself.
