The eternal question is: which gasoline is better. I personally don't bother about it. Gasoline of good quality. There is even an AI98. In mag, food prices are high. Therefore, only refueling.
I refuel because it is convenient on the way to work, plus there is a discount card. There is not always a tanker, but this is even good: one of them broke the latch on the gas tank hatch for me
I refuel only in Heliose. Good gasoline, enough for a long time. Excellent service. There is a card with cumulative bonuses.I recommended it to all my friends.Thank you.
