3. Why is the ethanol content increased specifically in the most commonly sold 95 octane petrol?In view of achieving the set climate policy objectives, the use of bio fuels must be increased the most in the most commonly used products. Due to technical constraints (tanks, pumps), petrol stations can continue providing mainly two petrol variants in the future, 95 and 98 octane, without needing significant investment. The same constraints also apply to the distribution system more widely.
By increasing the ethanol content of the most commonly used 95 octane petrol and keeping the ethanol content of the 98 octane petrol the same, it is possible to meet delivery obligations imposed by the legislation while ensuring the availability of suitable petrol for all engines.
Octane rating is the primary factor in the assessment of suitability of petrol for engines: low-octane petrol can be substituted with high-octane petrol, but not vice versa. If 95 E10 petrol is not suitable for an engine, the alternative is 98 E5. The goal is to maintain the fuel distribution logistics as simply and efficiently as possible, which is also in the interests of consumers.
