Is it okay to occasionally use 92 octane gasoline?
1 Answers
Occasional use will not have any significant impact on the vehicle. If a car that should use 95 octane gasoline is filled with 92 octane, knocking may occur during operation. The engine can tolerate minor knocking, but prolonged use of lower-octane fuel with frequent knocking can damage the engine and increase carbon deposits, placing a greater burden on the engine. Below are some additional tips for refueling: 1. Refuel when there's one bar left on the fuel gauge: You should refuel when the gauge shows one bar remaining, rather than waiting for the fuel light to come on. The fuel light indicates that the fuel level is already below the fuel pump, and refueling at this point can shorten the pump's lifespan. Too little fuel or running out completely may even burn out the fuel pump. 2. Don't overfill the tank: Filling the tank to the brim displaces air, allowing more fuel than the rated capacity to be added, which can also pose safety hazards. Filling only to the rated capacity meets safety requirements and reduces the vehicle's load.
