Fuel parameters, which most frequently did not comply with the required parameters were high distillation end of gasoline (1,5%) and lower octane number of gasoline, tested by research and motor methods (0,4% and 0,5%). Other inspected parameters showed only small deviations. Below 0,4% from the number of collected samples.
As far as diesel fuel is concerned, the parameter which most frequently failed to comply with the applicable requirements was the flashpoint value (8,3% from the number of collected samples). From the statistical point of view, other discovered variations may be considered as insignificant.
Testing of LPG fuel showed that the quality went down, when compared with the previous year. 8 samples from the entire number of 200 collected samples, failed to meet the required octane number tested by motor method, which represents (4,0%).
Detailed testing results obtained during 2008, including unsatisfactory criteria and values, are included in the appendix.

Inspections of bio additives in fuels.
Pursuant to amendment of Rule No. 86/2002 Coll., the air protection law and Rule No. 180/2007 Coll., specifying that a person, which introduces gasoline or diesel fuel, used in motor vehicles for transportation purposes to the taxable market in the Czech Republic, must make sure that these gasoline and fuels, which are being introduced to the market in the Czech Republic and will be used for transportation purposes during the applicable calendar year, contain the specified minimum amount of bio fuels.
Starting in September 1st 2007, the law specifies that the amount of bio fuels added to diesel fuels shall be 2 % of the applicable volume unit. For gasoline, the amount is also 2 % from the applicable volume unit, but the law takes effect on January 1st 2008. This number represents the total proportional volume of the entire volume of fuel sold on the market by the applicable and responsible person/business entity.
1216 samples of diesel fuels were tested for the contents of fatty acids methyl esters during 2008. Only one sample exceeded the established minimum amount. An average volume of FAME (MEMK) in diesel fuels, tested during 2008 in % of volume units is included in the chart. The average value of FAME during the entire 2008 was 2,2 % V/V.
The amount of ethanol in motor vehicle gasoline was tested in 1010 samples. None of the tested samples exceeded the maximum value.
The average volume of ethanol in gasoline samples tested during 2008 in % of volume units is included in the chart. During the entire 2008, the average value of ethanol was 1,3 % V/V.
Conclusion:
Fuel quality monitoring, performed by the Czech Trade Inspection Authority on the entire territory of the Czech Republic provides not only statistical data and information used by authorities in the European Union and but also helps to improve the quality of fuels and helps to make environmental and ecological criteria more strict.
