Just wondering if anyone has ever tried it in the 5.4 to quiet down the cam phasers

I have used it in my old cavalier with good results. Also my dad used it in his old exploder with a 4.0 and that thing ran mint when the body finally rotted off it

After reading eveyones stories i am now paranoid im gonna have a issue i noticed a slight diesel sound in my truck but it almost sound like its comeing from the injectors
