(Prague, December 22, 2011) In November, the CTIA inspectors took 239 fuel samples at filling stations on the whole territory of the Czech Republic. 11 samples, i.e. 4.6%, failed the quality standards’ requirements. Laboratory analysis showed deviations in quality in 3 motor petrol samples, 7 motor oil samples and 1 mixed motor fuel sample. Four samples were examined in a mobile laboratory and after poor quality was detected in 1 sample, selling of motor petrol was banned until remedy. In comparison with the previous month, the quality of motor petrol, motor oil and mixed fuel decreased. There is a suspicion of intended manipulation with fuel in totally 6 samples, i.e. in 3 motor petrol and 3 motor oil samples. The CTIA will keep on checking fuel quality till the end of the year.
