Is Honda XRV plus 92 or 95 better? Will XRV and 95 # gasoline have less carbon deposit?

The official suggestion of Honda XRV is to add 92 # gasoline. The advantage of 95 # gasoline is enough to avoid carbon deposition and detonation, but this is not necessarily an advantage. We still need to know the specific structure of the engine, and it is best to use the officially recommended fuel grade.

There is no difference in oil products between 95 # gasoline and 92 # gasoline, but it cannot be considered that 95 # gasoline is better. The main difference between them is the octane number. No.92 gasoline is rich in 92% isooctane and 8% n-heptane; No.95 gasoline is rich in 95% isooctane and 5% n-heptane. Because the octane number of 95 is higher than that of 92, the antiknock performance is better. Generally, engines with high compression ratio use high-grade gasoline, and engines with low compression ratio use low-grade gasoline. Because of the high compression ratio, the power of the car will increase accordingly and the stability will become worse, so better anti-explosion performance is needed.

Honda XRV plus 95 gasoline will have less carbon deposition. Carbon deposits need to be removed regularly. If it is not cleaned, there will be problems such as stuck throttle, unstable idle speed and large engine jitter. Generally speaking, it is cleaned after driving 10000 km. The best way is to clean the carbon deposit inside the throttle and engine.
