I knew Frank and in fact shared a warehouse with him in Saddle River, NJ back in 1982. This first exerpt is from his current promotional material:
WHAT IS Tufoil®
Tufoil is a precisely formulated blend of synthetic and mineral oils with electro statically charged sub micron particles of PTFE (polytetrafluoroethylene) and soluble molybdenum compounds suspended in and dispersed throughout the carrier. This additive mixes with both mineral and synthetic oils to provide the very best in protection from frictional wear and high temperatures. While there are those who may doubt the effectiveness of the Teflon inside the product we have an excellent analogy. Four households were each given the ingredients to make a chocolate cake but after baking only one came out tasting perfect yet they all had the same ingredients. The answer lies in how the ingredients were mixed and with the technical knowledge of the maker to create a perfect product. The manufacturers of Tufoil have a unique worldwide patented process, which provides a way to incorporate the Teflon into the product to make it the best additive available.

This conclusion seems to be borne out by tests on oil additives containing PTFE conducted by the NASA Lewis Research Center, which said in their report, "In the types of bearing surface contact we have looked at, we have seen no benefit. In some cases we have seen detrimental effect. The solids in the oil tend to accumulate at inlets and act as a dam, which simply blocks the oil from entering. Instead of helping, it is actually depriving parts of lubricant."

The Federal Trade Commission has filed suit in U. S. District Court seeking to halt false and misleading advertising for zMax auto additives and has asked the court to order refunds to consumers who bought the products. The agency alleges that enhanced performance claims for the product are unsubstantiated, that tests cited to support performance claims actually demonstrated that motor oil treated with zMax produced more than twice as much bearing corrosion than motor oil alone, and that the three different products - an engine additive, a fuel line additive and a transmission additive - were all actually tinted mineral oil. zMax is manufactured by Oil-Chem, a wholly-owned subsidiary of Speedway Motorsports, Inc. Speedway, based in Concord, North Carolina, operates NASCAR race tracks in the South and in California, in addition to marketing the zMax products.

Avco Lycoming, a major manufacturer of aircraft engines, states, "We have tried every additive we could find on the market, and they are all worthless."
Briggs and Stratton, renowned builders of some of the most durable engines in the world, says in their report on engine oil additives, "They do not appear to offer any benefits."
North Dakota State University conducted tests on oil additives and said in their report, "The theory sounds good - the only problem is that the products simply don't work."
