Eric, before you use anymore Z-max, I think I would go to this link and read what the FTC has to say about it.

Saw it -- and have to say that when I used it, it performed as promised fuel-wise, but felt no difference in engine or transmission behavior.

I see that article is dated Feb 2001. Here's what I found in followup:



Speedway Motorsports, Inc.
Oil-Chem Research Corp.
Assigned Attorneys:

Jonathan Cowen (BCP/ENF)
Edwin Rodriquez
Craig Lisher
Laureen Kapin
Michael Ostheimer (BCP/AP)
Melvin H. Orlans (OGC)
Alleged Conduct:

Deceptive practices in violation of Section 5, in connection with the marketing and sale of fake motor vehicle lubricant.

Complaint filed 1/31/01.
Trial deferred pending possible settlement

Now I iunderstand why I have not seen it for so long.

A friend of mine sells Amsoil products and I usually just get my stuff through him.

I am considering signing up for Amsoils preffered buyer program though, it allows you to buy their pruducts right from their website at dealer cost. The annual fee is $20.00 but I beginning to think I would save that much in no time if I was buying at dealer cost.

Go to this site for more explanation on their products, just one more note is their 10W-30 meets MB 229.3 specs. It is an excellent oil that will last 25k miles. I personally can't get myself to leave it in the that long but I have gotten better and now "only" change it a 5k mile intervals
