It seems to me to be as messy as just using the drain plug. I suspect the main body of the Valvomax is more than just hand tight in the pan. The cap is just hand tight.What are your thoughts on the ValvoMax quick twist oil drain valve? I saw Scotty's review and I thought it's pretty cool. However, I wasn't sure how to secure/screw it to the existing hole. It seemed like he just hand screw it in. If so, is that tight enough?
