What the studies showed
5 test reportsFresh and used samples
Fresh samples No. 812707 and No. 812708 were assessed as typical of the stated oil type. Critical contamination and wear metals were found in some used samples; oil changes and component diagnostics were recommended. The documents do not establish the outcome of the complaint review or the cause of all deviations.
Conditions and methodology
In-service sampling and testing at MITs GSM. Conditions, methods and specific samples are detailed in the original documents.
The results relate to the specified samples and equipment. Operating mileage or hours in an individual trial do not constitute a recommended drain interval for other machines. Follow the equipment manufacturer's instructions and all comments in the test reports.

Laboratory observations for each test report
Test report No. 812708 · 04.09.2024
The measured parameters are typical of the stated oil type. For a more precise assessment and interpretation of the results, comparative tests are needed using a product of the same name and guaranteed quality, or the full list of requirements for the lubricant or its quality certificate.

Test report No. 555277 · 04.09.2024
Comparison with fresh oil is needed for a more precise interpretation of additive package composition and base number. The other oil parameters are within normal limits. A fresh oil sample is recommended.
Test report No. 555280 · 05.09.2024
Critical accumulation of wear metals was detected. Silicon content is elevated, which may be due to leaks in the air intake system, a faulty air filter or external contamination. Contaminant levels (potassium and sodium) are critically elevated, which may be due to coolant entering the lubrication system. The other oil parameters are within normal limits. An oil change is recommended. Flush the system. Check the cooling system for leaks. Inspect components for wear. Diagnose the cylinder and piston assembly.
Test report No. 555278 · 05.09.2024
Appearance: the oil sample is clear, with dark sediment visible at the bottom. Wear element content is critically elevated. The additive package element composition differs from the fresh oil samples supplied previously. A critical build-up of contaminants (potassium and sodium) was detected. Coolant entering the lubrication system may be the cause. Oil viscosity is reduced, possibly due to fuel entering the lubrication system. The other oil parameters are within normal limits. An oil change is recommended. Check the cooling system for leaks. Carry out fuel system diagnostics.
