Yep, i know... snake oil, etc..
But has anyone tried XADO AMC? I have a lifter that ticks first thing in the morning. My donk has also done a fantastic 325,000 kms. I am giving it a birthday oil change and was thinking about adding some of this additive. It seems to have pretty good reviews and has been around for years. I know we all used to chuck a bit of Nulon in and various other potions.. but this stuff seems pretty genuine and could help an old engine get through its twilight years... a lot of reviews i have read even talk about smoothing out the lifters on our 4.0's...
What do you think??
