The engine before and after XADO RVS treatment
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Engine running time on a control sample of 200 g of petrol | 7 min 30 s | 9 min 36 s |
| Oil pressure at idle at 30 °C | 0.5 kgf/cm² | 1-1.25 kgf/cm² |
| Petrol consumption per lap of route No. 7 (as reported by driver S. Vrublevsky) | 18 l | 15 l |
Compression was measured in all eight cylinders of both banks — after the treatment it rose in every one of them. According to the driver, the bus became quieter and gained throttle response and power.
What the report recorded
The technical report of ATP No. 16330 JSC dated 13.03.2000 on the LAZ bus recorded: after the treatment, compression rose in each of the eight cylinders of the right and left banks; oil pressure at idle 0.5 → 1-1.25 kgf/cm²; on a control sample of 200 g of petrol the engine ran 7 min 30 s → 9 min 36 s. According to the driver, consumption per lap of city route No. 7 was 18 l → 15 l. All of this was obtained without disassembling the engine, on a vehicle with 58,034 km of mileage that continued to run its own route. The measurements were taken at 2030 km after the first treatment, and the report ends with the words: “Since the treatment is considered complete after 3500 km of running, we believe that the economic effect of applying RVS technology™ will be greater.”
The results relate to the petrol engine of a LAZ city bus treated with XADO RVS under normal service conditions; on other equipment and in other duty cycles the figures may differ. RVS is an obsolete XADO designation, the zero-generation compounds; the current product generation is revitalizants. The original report is published in full and available for download.
