In March, defects were found in samples of motor petrol, motor oil and mixed fuel SMN 30:
Out of 90 controlled motor petrol samples, 1 sample did not meet requirements (1.1%) as defects were found in quality parameters distilled content at 100°C, end of distillation, ethanol content and oxygen content by calculation
Out of 100 motor oil samples, 6 samples (6.0%) did not meet requirements. In all nonconforming samples, deviation in flash point was detected; in 2 cases, temperature 95% of distilled content was higher than the technical standard requires; 1 sample failed the parameter distilled content at 350°C.
Out of 5 taken samples of mixed fuel SMN 30, 1 sample (20.0%) failed the quality parameter flash point.
Violation of the upper acceptable level of bio ingredients in fuels was not detected.
Conclusion:
Analysis of the taken samples showed deviations from quality parameters in 6 motor oil samples, 1 motor petrol sample and 1 sample of mixed fuel SMN 30. In March, there were 3.7% of nonconforming samples. The higher rate of nonconforming samples (20%) in terms of the SMN 30 mixed fuel resulted from small number of samples taken.
On the grounds of extraordinary controls’ results at 2 filling stations, the CTIA issued ban on fuel sale until remedy. Out of these bans, 2 concerned selling of motor oil and 1 concerned selling of motor petrol SUPER BA-95. A mobile laboratory was used within these controls.
Just as in January and February, all 18 LPG samples, 2 samples of compressed natural gas (CNG) and 1 sample of fatty acid methyl ester (FAME) met requirements.
