¹Petrol that complies with the previous season's quality and that is stored in a filling station tank to which fewer than 3 deliveries of petrol have been made since 6 weeks before the beginning of the season is regarded as complying with this specification.

²Indicative 50 ppm maximum sulphur content from 2008; ultimate requirement for "sulphur-free" petrol of 10-15 ppm maximum sulphur content.

³The sale of ethanol-blended petrol must be accompanied by consumer information about the possible vehicle maintenance requirements that may result from using ethanol blends. Up to 11% volume MTBE allowed until 1 March 2003, as long as the total volume of all oxygenates does not exceed 11% by volume.

⁴To be reviewed by 2006.

⁵Petrol that complies with the previous season's quality and that is stored in a filling station tank to which fewer than 3 deliveries of petrol have been made since 6 weeks before the beginning of the season is regarded as complying with this specification.

⁶Indicative 50 ppm maximum sulphur content from 2008; ultimate requirement for "sulphur-free" petrol of 10-15 ppm maximum sulphur content.

⁷The sale of ethanol-blended petrol must be accompanied by consumer information about the possible vehicle maintenance requirements that may result from using ethanol blends. Up to 11% volume MTBE allowed until 1 March 2003, as long as the total volume of all oxygenates does not exceed 11% by volume.

⁸To be reviewed by 2006.

⁹These are maximum criteria; cold flow properties of a fuel must be fit for common purposes in the region and the season in which it is sold. Diesel that complies with the previous season's quality and that is stored in a filling station tank to which fewer than 3 deliveries of diesel have been made since 6 weeks before the beginning of the season is regarded as complying with this specification. Sales for marine use may be summer grade at any time of the year.

¹⁰The limit for sulphur does not apply to sale for marine use. Diesel sulphur content to be reviewed by mid-2005; 10-15 ppm maximum sulphur content to be required no later than 2009-2010.
