During cleaning, lead bearing
wear dropped to NIL; lead wear is
a bit elevated by a dirt leak probably
at the air filter or intake area. Auto-Rx®
while installed stopped the bearing
wear. |

Ingested dirt from air filter
or intake , lead wear is being elevated
by this but the Auto-Rx® treatment
helped slow the wear rates. Air filter
and any dirt leaks on engine need to
be corrected. |

Bearing overlay and assembly

no wear during cleaning phase. Spike
in tin is also related to dirt ingression
in Rinse Phase. |

Note MAJOR drop in solids
production during cleaning phase, level
returns to normal during Rinse Phase. |
Oxidation |
29% |
38.5% |
45.5% |
Elevated trend indicates
Auto-Rx® cleaning action
is ongoing and active, oil is NOT oxidizing,
but the cleaning of deposits is. |
Nitration |
25% |
31% |
16% |
A good measure of combustion
efficiency and high levels of nitration
contribute to and enable varnish formation.
Post Auto-Rx® drop in nitration means
the cylinder is making much improved
power, confirmed by correlating compression
checks of up to 50 PSI increase. |

Test 1 shows a normal shear trend for the oil and indicating SAE 40w, test 2 shows a oil that is SAE 20w grade and probably sheared from SAE 40w, test 3 is normal, solid SAE 50w as designed, in other words a clean engine doesn’t shear a average oil as easy. |

Conclusions:
|
Relatively new HD engine on HD
oil. Maintained
by professionals of AMI. Saw impressive
gains in performance and efficiency
while dropping key wear areas in
spite of an air or dirt ingression
leak that persists throughout test.
Our conclusion is that Auto-Rx®
should be used in all Harley
Davidson engines at least every
5,000 miles or annually. The
Auto-Rx® treatment compensates
for the lack of oil quality
and real world dirt and cleanliness
issues that all bikes will
experience.
