But every oil change after this from now on, if it's three months, 3,000, I'm going to be putting the cleaner in it because I want to prevent this engine from having to make it. You could have a ring that's hanging up. You could have a broken ring that's spinning, you know, that's causing it. Sometimes it lines up. Moving around. And sometimes it doesn't.
