Should the 10th-generation Accord 1.5T use 92 or 95 octane gasoline?

If the 10th-generation Accord is equipped with a 1.5-liter turbocharged engine, it is recommended to use 95 octane gasoline; if it is a hybrid model, 92 octane gasoline is sufficient. The relevant details are as follows: Difference between 95 and 92 octane gasoline: There is no difference in quality between 92 and 95 octane gasoline. The main difference lies in their octane ratings, which directly affects their anti-knock performance. The fuel grade specified by the manufacturer is the most suitable for the engine. Higher octane gasoline does not necessarily provide more power to the engine. The appropriate gasoline grade for an engine depends on its structural design. Fuel tank capacity of the 10th-generation Accord: The fuel tank capacity of the 10th-generation Honda Accord is 56 liters. The 10th-generation Accord uses three types of engines: a 2.0-liter naturally aspirated engine, a low-power version 1.5-liter turbocharged engine, and a high-power version 1.5-liter turbocharged engine.

Since I bought the car, I've been driving the 10th-generation Accord 1.5T and using 95-octane gasoline. Initially, I tried 92-octane, and it ran smoothly for the most part, but I noticed occasional minor jerks during acceleration. Turbocharged engines inherently require higher octane fuel, and 95-octane, with its higher octane rating, helps reduce the risk of engine knocking, especially when running the AC at high speeds or under heavy load. The manual states that 92-octane is the minimum requirement but recommends 95-octane for optimal performance. Although it costs a bit more per liter, the difference in fuel consumption averages out to be negligible—I calculated that a full tank costs about 10 yuan more, but in exchange, there's less engine wear over a year. Now, I'm accustomed to using 95-octane, and it gives me more confidence when driving. If budget is tight, 92-octane is acceptable, but it's important to regularly check the spark plugs and air filter to ensure engine health. Ultimately, fuel choice depends on your driving habits—for city commuting, 92-octane is sufficient.

As someone who works on cars every day, I've dealt with many Accord 1.5T engine issues. The manufacturer recommends a minimum octane rating of 92, but I personally recommend 95-octane gasoline. The reason is that turbocharged engines operate under high pressure, and 92-octane fuel in areas with poor fuel quality can easily cause knocking, damaging piston rings. Customers report fewer warning lights, quieter engine operation, and more stable fuel consumption when using 95-octane. While 92-octane is acceptable, long-term savings may lead to more carbon buildup and costly repairs. I suggest sticking with 95-octane from the start to avoid potential damage. In high-load driving situations like mountain roads or when fully loaded, 95-octane offers better protection. Fuel quality varies significantly, so choosing reputable gas stations is advisable.

I choose 92-octane gasoline for my Accord 1.5T purely to save money. The slightly cheaper price per liter adds up to tens of yuan in monthly savings, which is great. The engine is designed to run fine on 92-octane—it operates smoothly without major issues, and the fuel consumption in city driving is normal at 7-8 liters per 100km. While 95-octane might feel a tad smoother, the difference is negligible. For daily commuting in heavy traffic, using 92-octane is entirely reasonable. The long-term savings can be allocated to better maintenance, like oil changes. If you frequently drive on highways or prioritize acceleration performance, 95-octane might be worth it, but I prioritize economy.
