got dammit. i just spent like 50 bucks on zmax after about a year after seeing infomercial. i lost my reciept and i just found out about all these lawsuits and false claims. i guess im gonna go ahead and apply the product unless anyone has had any serious damage to their engines.

i used zmax after seeing the infomercial. as they said the car ran more smoothly and the gas mileage increased for probably 2 months or so, but then it got worse than before adding the additive. i used to get 18mpg, for 2 months i got 20, and then it plunged to 16mpg ever since and i also have some engine vibrations that i didn't have earlier. IT AIN'T WORTH IT!!!
oh, and don't chuck it into the trash. its like engine oil. its supposed to be dropped off for recycling.

We bought zmax for our 1948 Pontiac Silver Streak, the engine ran excellently and now it is gone....At this point we know the bottom end is toast, we don't know wher ewe are going to be able to purchase bearings and we hope that nothing has happened to the crank...because we have no idea where we will be able to get another engine...It is a Flat head 6 cylinder 6 volt engine....
We are still doing research to see if the guarantee is good in Canada...I doubt it though....They are a rip off, $50. for garbage...Don't do it!!!! DON'T add the crap....

Don't you guys know, if any of these oil additives really worked, the oil companies would be on top of it? After all they have the billion dollar labs & top chemists.
