Key results

compression evened out across the cylinders

↑12.5-24%

compression across the cylinders, 25-28 → 31-32 kgf/cm²

↓15.4%

fuel consumption at idle, 1.88 → 1.59 l/h

↓7×

oil consumption, 2.2 → 0.3 l over 6 h of heavy work

MACHINE	HOURS RUN AT START OF TREATMENT	WHAT WAS MEASURED
MTZ-82 tractor, reg. No. 2372 ke 23 RUS	2354 engine hours	Compression in all four cylinders, fuel consumption at idle, oil consumption

D-240 engine — compression by cylinder, 581 engine hours of running

ZEGA 363 compression tester. The largest gain is in the weakest cylinder: the coating builds up where the wear was, so the cylinders converge on a single value. The report concludes that compression rose by 12-20 %.

D-240 engine — fuel and oil consumption

PARAMETER	BEFORE TREATMENT	AFTER TREATMENT	CHANGE
Running time on 100 ml of diesel fuel, idle	3 min 12 s	3 min 47 s	+35 s
Specific fuel consumption, idle	1.88 l/h	1.59 l/h	−15.4 %
Oil consumption over 6 hours of heavy work	2.2 l	0.3 l	−1.9 l · 7×

Fuel consumption was measured with a metered portion of 100 ml after 581 engine hours; oil consumption — from five years of tractor service following treatment.

What was treated and when

UNIT	TREATMENT	RESULT
D-240 engine	XADO gel revitalizant, 3 stages	Compression rose and evened out, fuel and oil consumption fell
Injection pump	XADO gel revitalizant for injection pumps, 1 stage	Recovery of the plunger pairs — per the report’s conclusion, a contribution to fuel savings
Transmission units	XADO gel revitalizant for gearboxes and final drives	5 years of service without failures
Power steering	XADO gel revitalizant for power steering	5 years of service without failures

Treatment was carried out 05.09–01.11.2003 without dismantling the units and without taking the tractor out of service.

Conclusions of the report

The farm and XADO engineers recorded in the report: 1. Measurements of the operating parameters of the D-240 engine fitted to the MTZ-82 tractor showed that, as a result of treating the engine with XADO compounds and running it for 581 hours, compression evened out across all cylinders and increased by 12-20 %. 2. The rise in compression and its evening out across the cylinders indicate recovery of the existing wear on the working surfaces of engine parts, an increase in engine power and optimisation of the fuel combustion process. 3. The 15 % reduction in fuel consumption also points to recovery of wear on the injection pump plunger pairs and to a lower friction coefficient of engine parts and transmission units. 4. Over the 5 subsequent years of this tractor's service all engine systems and the transmission worked properly, and oil consumption fell from 2.2 litres to 0.3 l over 6 hours of heavy tractor work, or roughly 7×.

The results relate to an MTZ-82 tractor with a D-240 diesel engine in field service at a peasant farm enterprise; on other machinery and under different operating conditions the figures may differ. The original report with signatures and seal is published in full and available for download.
