Changing oil with a sump plug and sump plug wrench
When you’re replacing oil, you normally need a sump/ oil pan plug wrench to loosen a sump/ oil pan plug. And you can’t just use any random tools, you need a wrench that is exactly the right size. If you use a wrong size wrench, the sump plug can be severely damaged. In addition, the threads of the plug or oil pan may be damaged if the sump plug is over torqued while putting it back after changing the oil. Sometimes the damages are so bad that there are a lot of costs involved. A severely damaged sump thread or broken sump/ oil pan plugs are just some of the problems that you may have to deal with.
