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:

FTC v. SPEEDWAY MOTORSPORTS, INC., No. 1:01CV00126 (M.D.N.C.)

Parties:

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.
Status:

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


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