You can get a clean oil drain pan with the easy pour spout for like $5 and then you can just reuse your oil. A lot of dealerships do it like that and as much as it is for and oil change, I've had to do it as well. Just keep the dirt out and you'll be fine. Also try not to scour the oil pan when taking the gasket off if it is stuck on there.

The torque for the bolts should be 10 ft/lbs
