Can a 92 Octane Engine Use 95 Octane Gasoline?
2 Answers
An engine designed for 92 octane gasoline can use 95 octane gasoline, but there may be certain impacts. Below is relevant information about 92 octane gasoline: 1. Fuel Introduction: "Motor Gasoline" (GB17930—2013) was jointly drafted and revised by the Petrochemical Research Institute of China Petroleum & Chemical Corporation, the Petrochemical Research Institute of China National Petroleum Corporation, and the China Automotive Technology and Research Center. Previous versions include GB17930—1999, GB17930—2006, and GB17930—2011. 2. Specification Indicators: "Motor Gasoline" (GB17930—2013) for the first time specifies a density index, set at 720～775kg/m³ at 20℃, to further ensure relatively stable fuel economy for vehicles. Compared with GB17930—2011, the most significant changes can be summarized as "three reductions, two adjustments, and one addition."
Yes, you can! The engine was designed with compatibility in mind when using 92 octane. If you use 95 octane gasoline, which has a higher octane rating, the engine's computer will automatically adjust the ignition timing to adapt, preventing knocking or engine damage. I often do this, especially when traveling and gas station options are limited. Filling up with 95 octane once in a while makes the ride feel a bit smoother, but the difference isn't significant—don't expect a sudden power boost or better fuel economy. The key is to stick with good-quality gasoline and avoid using a lower octane than recommended. Overall, it's a convenient option, but there's no need to spend extra money daily—92 octane offers better value and practicality.
