Measurements were taken and certified by the customer's compressor station personnel. The card above shows the typical reduction range across 27 measurement points.

Main oil pump: lubrication system pressure

PARAMETER	BEFORE TREATMENT	AFTER THREE STAGES
Pressure delivered by the main oil pump	4.9 atm	5.5 atm

At each of the three treatment stages the pressure rose by 0.2 atm within 40–50 minutes after the compound was introduced — the response repeated three times.

Noise level at the compressor station, dB

Conclusion of the work acceptance certificate

The certificate, signed by the chief engineer of State Enterprise "Malyshev Plant" and sealed with the enterprise stamp, states: "The test results demonstrate the effectiveness of applying the technology at State Enterprise 'Malyshev Plant'". Behind this wording are measurements taken and certified by the customer's own personnel. After 439 hours of operation, vibration displacement at the bearings of the compressor, gearbox and electric motor decreased within a typical range of 30-60 %, and at the main oil pump from 45 to 4 µm vertically and from 35 to 6 µm axially. The pressure delivered by the oil pump rose from 4.9 to 5.5 atm: the restored pump clearances hold pressure in the lubrication system again. The unit was neither disassembled nor taken out of service — the compound was introduced into the oil of a running machine.

The results relate to the K-500-61-1 turbocompressor at the compressor station of State Enterprise "Malyshev Plant"; on other equipment and under other operating conditions the figures may differ. RVS is an obsolete XADO designation for zero-generation compounds; the current product generation is revitalizants. The original report with signatures and stamps is published in full and available for download.
