Engine oil analysis, of a 2012 Suzuki DR 650 motorcycle, showed the engine soot was totally eliminated and engine lifespan was doubled after Xcelplus treatment:

100 % reduction in Soot
55 % reduction in metal wear (equivalent to a doubling of engine life)
59 % reduction of particles in the engine (less particles = less wear, noise, vibration & a lower temperature)

Engine oil analysis, of a 2015 Toyota Yaris 1.3 L hatch, demonstrated a ~5x increase in engine lifespan after Xcelplus treatment.

82 % reduction in wear

1/5 (18 %) normal wear is equivalent to a five times increase in engine lifespan

Automotive Service Councils of Pennsylvania

Ran three cars without oil:

Three cars were treated with Xcelplus Engine Treatment. 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.

Conducted a full load test on Xcelplus Engine Treatment proving:

Internal engine friction decreased while horsepower and torque increased.

“a single treatment with <Xcelplus Engine Treatment> will provide substantial savings due to improved engine efficiency and lubrication”

Test results at full load show:

17 % increase in acceleration
16 % reduction in friction
15 % decrease in oil temperature
4.7 % increase in torque
4.7 % increase in horsepower

Federal Aviation Authority (USA)

FAA testing of an aircraft engine treated with Xcelplus Aircraft Treatment found:

25 -30 % decrease in engine friction at take off and at cruise RPM's
80 ~ 90 % reduction in wear i.e. 5 ~ 10x increase in engine lifespan

Also, oil consumption after ten hours of testing was a mere one pint. (Normal acceptable oil consumption averages one quart per two hours)

The report concluded that it:

“..would consider all findings to be better than acceptable standards."

Army: Fort Hood (USA)

Found virtually no wear or deterioration to all components treated with Xcelplus products. All internal parts were sent to a N.A.S.A. lab for detailed inspection.

Testing at N.A.S.A. proved the coating to be 1 micron thick and bonded to the metal surfaces.

Franklin Institute (USA): picture of coated surface

Tried to remove the permanent coating that Xcelplus products apply to lubricated metal surfaces but were unable to do so. They concluded that:

‛‛The above experiments show that coating to be 1 to 2 microns thick and bonded to the surface.”

Cranfield University (UK): 5 yr test

Tested the effect Xcelplus Engine Treatment has on metals. This test led to two important conclusions:

• Compared to ordinary oil, the Engine Treatment dramatically extends the life of the metal (+60-80 %)

• The treatment coats the metal surfaces, causing the treated "dry" metal to outperform untreated "dry" metal
