has anyone tried this in their max? if so, did it give you better gas mileage?horsepower?

 

Don't even try it. I think they are sue by some government agency for making false/untrue claims.

If you really want more protection, use synthetic oil (Mobil 1, Amsoil, Redline).

 

Correct, the government sent the company that makes Z-max a cease-and-desist letter, ordering them to stop all false advertising. Almost every claim the company made was proved to be false. Zmax is a scam, pure and simple.

 

So far the only action the government (FTC) has brought up against the makers of zMAX is a complaint (civil action) for the US District Court in Greensboro, NC, to

• "issue injunctive and other relief against violations of the FTC Act and,
• in the exercise of its equitable jurisdiction, to award redress to remedy the injury to consumers,
• to order disgorgement of monies resulting from Defendants' unlawful acts or practices, and
• to order other ancillary equitable relief."

The decision is still pending. If you want to know more, here's a zipped PDF copy of the complaint, freely available from www.ftc.gov.

But to answer your question, I don't think anyone on this board has tried to poison their VQ with it so we don't reallyknow whether it works.

 

thanks for the info.im glad i didnt waste $40..

 

What is Z-max?

 

An engine oil additive.

 

I used to see the infomercials for this product about every Sunday afternoon 6 months ago...had all these claims of saving you money. Guess that is was supposed to clean out the carbon deposits in the engine and thus give you better gas mileage which led to saving you money at the pumps...
