I have used these on my last 3 cars and they work perfectly, no leak, no grounding, etc. This one fits the base car oil pan...They have updated to a nipple that has a snap on oil tube to 3/8 hose so there is no mess. It is the Fumoto F107S off their site, google "qwikvalve" Just posting to add content here.
