Where can I get Magnetic Drain Plugs? I posted the other day about finding shavings in my used oil. I found a peice that has to be off my current drain plug. The thing will screw in by hand then you'll have to use wrench then go by hand again. want the magnetic to get anything else out that might be in there as well as keep it clean. Any other suggestions before I beat on my car again. Going to change the oil after about 100 miles to see if theres anything else going on. Thanks
