Where is the fuel filler switch located in a Mazda?

The fuel filler switch in a Mazda is located under the seat, together with the trunk switch. Here is some relevant information: 1. Fueling precautions: The vehicle manufacturer specifies the type of fuel to be added before the car leaves the factory, and the gasoline grade depends on the engine's compression ratio. If the car requires high-grade gasoline but low-grade gasoline is accidentally added, the engine may experience knocking, reduced power, increased water temperature, and metallic knocking sounds during operation. However, there is no need to worry excessively, as the engine will return to normal as long as high-grade gasoline is used the next time. Additionally, do not wait until the fuel tank is empty before refueling. 2. Gasoline knowledge: Octane rating, the gasoline grade is determined by the octane rating, and the higher the octane rating, the better the anti-knock performance. Long-term use of gasoline with a lower grade than required by the car is equivalent to using inferior gasoline. Due to the mismatch with the vehicle's compression ratio, incomplete combustion of gasoline can lead to increased engine knocking, reduced power, increased fuel consumption, and more carbon deposits in the cylinders and valves. Continuous knocking can also damage the piston rings, break the connecting rods, and significantly shorten the engine's lifespan. Leaded gasoline, which contains lead, can cause oxygen sensor poisoning, clog the exhaust pipe and three-way catalytic converter, and reduce engine power. After using leaded gasoline, the spark plug insulator usually appears white or yellow. Gum content represents the stability of gasoline. Excessive gum content can cause deposits in the intake system or sticking of the intake valves. Generally, the unwashed gum content in gasoline before adding cleaning agents should be below 30mg/100ml. If the gasoline gum content is too high, the intake system may experience procedural issues. Additionally, excessive sulfur content can cause oxygen sensor poisoning and failure, leading to poor acceleration, sulfur poisoning and failure of the three-way catalytic converter, excessive emissions, clogging of the three-way catalytic converter with sulfur-phosphorus chemical complexes, corrosion of metal parts, and damage to the aluminum alloy cylinder block and exhaust pipe.
