For me, I just like wrenching on them! I have a system where when I take the drain plug out, I put new crush washer on and tighten it back up. I know it's tightened to specs. Same with the oil filter; never had one to leak. I get the chance to look around for any leaks, check hoses, etc. I know my oil level is right and double check everything before I drive it again.
have had my share of " quick lube" places leave the drain bolt too lose...oil filter too loose, etc.
