Anybody tried Zmax?

[PCA4208]

I was wondering if anybody out there has tried Zmax? It's supposed to work wonders in your oil and fuel systems. And because its not really an additive, but a substance that is carried by the oil, it doesn't change your levels because it soaks into the metal. I was thinking of putting this stuff in my truck, but I'd like to hear from some people that have already done it.
THANKS

From what I've read online... It's a waste of money.

I've use it both my trucks once every 10,000 miles. When I had to rip my wife truck motor apart, it have barely any carbon build up. I used both the fuel and oil. Look at trucku.com and they did a real world test on it.

About the only additive i would use at all and that would be a last straw idea is lucas...Most of that stuff has been long term tested and can actually be corrossive....Look into gettin some work done with a company called micro blue...MPG to be had with just wheel bearings alone and they are well known in the race world..I have never used them myself but i know of people who have used them in engine rebuilds on 18 wheelers and motorcycles..If memory is rite the best fella to talk to about it is craig(not to be confused with me..lol"

Fluid wise, If it's not in the service manual, don't add it.

If it's not in the service manual, don't add it.

Pretty sure most stuff we do to our trucks isn't in the service manual haha
