Does Earth Dreams Engine Have Less Carbon Deposits with 95 or 92 Octane?

[PrestonMarie]

There is no difference. Whether using 95 or 92 octane gasoline in Earth Dreams engines, it has no relation to carbon deposits inside the engine. Different gasoline octane ratings represent different octane values, primarily affecting the fuel's anti-knock properties. Gasoline Octane Rating: The octane rating indicates the gasoline's anti-knock performance and has absolutely no connection with cleanliness or delaying carbon deposit formation. However, using the wrong engine oil can indeed affect the vehicle. In reality, all gasoline-powered vehicles will inevitably face carbon deposit issues—it's just a matter of sooner or later, more or less. Direct Injection Technology: Honda's Earth Dreams series engines employ direct injection technology, which inherently tends to cause carbon buildup on fuel injectors and intake valves. Currently, there is no effective solution, making the maintenance and upkeep costs of direct injection engines relatively higher. From a usage perspective, as long as you use high-octane fuel normally and change the engine oil regularly (preferably using full synthetic oil), carbon deposits won't affect normal operation.
