No worries..... so you think use 1/4 inch rachet sparingly?
That is what I do. I just use feel for the Oil Filter cap and make sure it's tightened evenly. There is only 1 drain plug for the oil on the P500s. I don't buy a new crush washer every time and have had no issues with leaks at all. I have 1300 miles on my 2018 P5 and have done the oil changes/maintenance myself since day 1. However they (crush washers) are cheap to purchase each time. In my opinion it's kind of an owners preference type of thing. I can only hope that someday down the road my choice to not replace it every time doesn't bite me in the kiester and cause me some trouble. I do check it regularly though. All the best to you sir!
