Consumers Digest (Proof of claims)

In the July/August 1981 issue of Consumers Digest, We admitted a lack of
knowledge about engine treatment products ("Questions & Answers"). A deluge of
inquiries and testimonials followed, so we investigated further.
We were somewhat skeptical at first, but it
turns out that the product does exactly what the manufacturer claims it does. In
fact, the more we looked, the more facts stacked up on the products side.
The fact that it reduces engine wear --- that
it does attach to metal parts has been verified by tests conducted at the
Franklin Institute, the University of Utah Engineering Experiment Station, and
by the La Tourneau College in Texas. The FAA has approved the product for use in
aircraft, and another product for small engines (motorcycles, lawn
mowers, and so on) has also been favourably tested.
Perhaps most dramatic, the Automotive Services Councils for Pennsylvania, Inc.
performed a torture - test with excellent results.
Three cars, with between 75,000
(120,000 km) and 129,000 miles (206,000 km)
on them, were treated. Six months later, the oil was drained from each vehicle,
and the cars were driven, without oil plugs, for about a half hour. The water
temperature never rose, and the engines sustained no apparent damage.
Note: These tests were performed with XcelPlus Formula 101 marketed under
another private label.
