zMAX® - Testing - FTC | Oil Additives | Bob Is The Oil Guy

Zmax is so bad they were sued by the FTC and got their asses handed to them in court. It's the textbook definition of snake oil. You should do some reading form places other than the manufacturer of the snake oil.

Also, definitely don't put additives of any kind in an automatic transmission - they're very sensitive to the exact properties of the lube in them and/or any contaminants (and I'm not sure what you're referring to about CVT, but the Z doesn't come with a CVT).

I haven't chimed in on this thread, but I know I have on others.

My cousin bought a Yamaha POS something or other that wouldn't kick over, figured the fuel had gummed up from sitting so long. Put some Marvel Mystery oil in the oil and gas tank, would start, but not run super well, dumped a shítload of Seafoam in the gas tank, ran like a champ. Cleaned the jets in the carbs and the bike got beaten until the day it got jacked...

I did also run it through the intake on my Avalon (RIP), and when it needed a rebuild, you could see that one bank was clean as a whistle, the other was gummed to hell.

@Chuck - before you tear me apart, maybe check the facts. The only reason a case was brought before the FTC was because one of the major oil companies lodged a complaint. If you read the entire FTC final outcome and what has proceeded since then you would see all claims were proved by legitimate ASTM/SAE testing and all claims that were made before the FTC hearing are still being made today as there is proof of such claims. The only claim they cannot make is what percentage gas mileage increase they can provide. - it works as advertised for me. DONT USE IT IF YOU DONT WANT TO!! - The FTC suit was only in regards to zmax guaranteeing a certain % of better gas mileage which is different to every vehicle. Every claim/study or scientific proof they had used before the suit is still allowed to be stated now, and is. Maybe next time read the link you post before posting it

My wife and I use this technique all the time - I look for smoke and she says "I know its working because its tingling"

so i keep going!

:happydance:

I was told that you might need new O2 sensors. I ran it in my 240sx and never had any issues, drift and grip she was run really hard.

Has anyone used the CRC intake valve cleaner? It should be the same concept as seafoam

For anyone who stumbles across this thread in the future here's about as scientific a look at Seafoam as possible. It works.

Added a video by "Chris Fix" to complement those added by dinfire.

He took a before and after scope of a 2008 Honda Civic Si engine and it very clearly was cleaner after the treatment.

In another video, he scoped and had before and after with several other products, including Techron. He saw no to very, very, very minimal benefit with any product, some appeared to be worse. The only one that worked was seafoam.

He used the aerosol version through the throttle body. I have never used Seafoam but I did buy a couple aerosol cans, I may do the brake booster method and use the cans on another vehicle.
