Diesel rises more than gasoline
The daily evolution shows a different behavior between both fuels again. Gasoline 95 adds half a cent per liter, while diesel A increases by 1.1 cents.
The greater increase in diesel causes the difference between the two to narrow to 0.9 cents. A week ago, the distance was greater and gasoline was already above diesel in the national average.
Gasoline 98 exceeds two euros per liter
Gasoline 98 reaches this Thursday 2.069 euros per liter, according to the latest available update of official prices. The amount is 15.5 cents above gasoline 95.
Premium diesel remains slightly below two euros, with an average price of 1.996 euros per liter. In both cases, the prices correspond to the stations that sell these fuels and report their rates to the Ministry.
The average price changes according to the gas station
The national average does not necessarily match the price that each driver will find. Service stations apply different rates and the differences are especially wide between provinces.
This Thursday, gasoline 95 ranges between a provincial average of 1.487 euros per liter in Las Palmas and 2.033 euros in Balearic Islands. The difference reaches 54.6 cents per liter, which amounts to 27.30 euros in a 50-liter tank.
Fuels chain new increases
The day leaves another increase in the main fuels. Gasoline 95 reaches 1.914 euros per liter and diesel A reaches 1.905 euros, while gasoline 98 exceeds 2.06 euros.
With these prices, filling 50 liters costs 95.70 euros with gasoline 95 and 95.25 euros with diesel A. Thus, the price of gasoline today maintains a difference of just 45 cents per tank compared to conventional diesel.
