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.
