Frequently Asked Questions
Why do fuel prices rise during holidays?
Fuel prices tend to rise during holidays because more people are travelling, which increases demand. This seasonal price surge is a common occurrence around the world.
Is it better to fill your tank completely or only partially?
Filling your tank completely can reduce the number of trips to the petrol station and help minimise fuel evaporation. However, carrying a full tank adds weight, which can slightly decrease your fuel efficiency.
Why are petrol prices higher on motorways?
Motorway service stations typically have higher fuel prices due to several factors, including higher operating costs and limited competition.
Are independent fuel stations more expensive than larger ones?
Independent fuel stations might have higher prices because they often have less purchasing power and receive fuel deliveries less frequently compared to major chains. This can lead to higher costs for the independent stations, which are then passed on to consumers.
How often do fuel prices change?
Fuel prices can fluctuate daily due to various factors, including changes in crude oil prices, currency exchange rates, and regional competition.
Why do rural areas have higher fuel prices?
Fuel prices in rural areas are often higher because of increased transportation costs, lower competition, and less frequent fuel deliveries compared to urban areas.
