Gasoline Oxidation Stability Tester is a specialized laboratory device used to evaluate the oxidative stability of gasoline. This test determines how well gasoline resists oxidation during storage, which is crucial for maintaining fuel quality and performance. The tester typically operates by exposing a sample of gasoline to accelerated oxidative conditions, often involving elevated temperatures and pressures, to simulate long-term storage effects. The results help in predicting the fuel's shelf life, ensuring it meets regulatory standards and remains effective for engine performance over time.
