Oil price: The prices of gas stations all over the country are uniformly set by the National Development and Reform Commission. Gas station: Sinopec or PetroChina are common in gas stations, and the quality of oil products is guaranteed. Emergency refueling: ordinary passenger cars can generally run 500 or 800 kilometers when their fuel tanks are full. In case of running out of oil, there is an emergency telephone every 1-2 km outside the high-speed baffle, and there are oil delivery, trailer and maintenance services in the service area.

The oil price of private gas stations is cheaper than that of state-owned gas stations, but its oil quality cannot be guaranteed, so the oil price and oil quality of private gas stations cannot be compared with that of state-owned gas stations. When choosing gas stations, riders should try to choose state-owned brand gas stations, such as those of PetroChina, Sinopec and CNOOC, with guaranteed quality.

The difference between expressway service area and parking area

The service area provides parking lots, toilets, gas stations, auto repair shops, restaurants and canteens, with an average distance of about 50 kilometers. The parking area provides facilities such as toilets and benches and a small number of parking spaces. The service court is mainly divided into unilateral service court and bilateral service court. Parking areas are mainly divided into observation deck along the road and general parking areas.

The service area has the characteristics of liquidity and fluidity of the service object, one-time and single service object, uncertainty of passenger flow, diversity of service demand and particularity of geographical location. The parking area not only has the characteristics of the mobility and fluidity of the service object, the one-off and single service object and the instability of passenger flow, but also has the characteristics of improving highway traffic safety and effectively reducing construction and management costs.
