With the onset of summer, the drivers are asked which gasoline is best used-A-92 or A-95? The difference between them is the octane number, which reflects the resistance of fuel to detonation-premature ignition of the fuel and air mixture in the engine.
High air temperature and increased pressure in the cylinders increase the risk of detonation. A-95 gasoline has higher resistance to this process that protects the engine and helps to maintain its optimal operation. Modern cars can adjust the moment of ignition to avoid damage, but these systems are not limitless. The use of A-95 reduces the load on the engine and increases its efficiency, especially in heat, with high loads or in mountainous terrain. Another important point is the quality of fuel. Only refue to the tested gas stations, because even the best octane number will not save the engine from bad gasoline.
If the manufacturer of your car allows both options, it is better to choose A-95 in the heat-this guarantees a more stable and safe operation of the engine.
