I have a buddy who has been running a Frantz filter on his 7.3L for a couple months now. He tested his oil before he put it on and then again last week and says the results came back like he hadn't run his truck at all. I was a skeptic when he first talked about it but I'm thinking about trying it on my 6.0L now. Has anyone ever installed one of these on their 6.0L? I'm no mechanic but seems pretty simple in the video. Thanks!
