Should the Changan Eado Plus use 92 or 95 gasoline?

[SanKendra]

Both the 1.6L and 1.4T versions of the Changan Eado Plus can use either 92 or 95 gasoline. The difference between 92 and 95 gasoline is not about quality but rather the content of added isooctane, which affects the gasoline's anti-knock properties. 95 gasoline has a higher isooctane content, making it slightly more expensive and offering better anti-knock performance. Generally, it is not recommended to use gasoline with a lower octane rating than what the car manufacturer specifies or recommends. Using lower-octane gasoline can cause premature combustion, leading to engine knocking. Incomplete combustion can also increase carbon deposits, clogging ducts and injectors, and may result in reduced vehicle power and higher fuel consumption. Similarities between 92 and 95 gasoline: Same cleanliness: The misconception that higher-octane gasoline prevents carbon deposits is incorrect. Gasoline octane ratings only indicate the difference in isooctane content and have no relation to cleanliness. Same heat value: The claim that 95 gasoline is more fuel-efficient is incorrect. The national standard for gasoline density has a range, so even with the same 92 gasoline, a full tank's range can vary by up to 50 kilometers. Precautions for refueling: Gasoline octane rating: Gasoline comes in several types, each with different component ratios, leading to varying performance. Always check the gasoline octane rating before refueling. Avoid overfilling after the pump stops: Many gas station attendants may continue adding fuel after the pump stops to round up the charge. However, in summer, fuel expands due to high temperatures, which can damage the fuel tank. Fuel additives: Gas station attendants often recommend fuel additives, but these do not fundamentally solve engine carbon deposit issues. It's best to avoid using them. Beware of static electricity: In winter, dry climates can easily generate static electricity. Always take precautions against static electricity when refueling to prevent serious consequences.

As a long-time owner of the Yidong Plus, I can confirm the official manual clearly recommends 92-octane gasoline, which works perfectly fine. While 95-octane is a higher grade, its benefits are tailored for high-compression engines. The Yidong Plus engine is cleverly designed with a moderate compression ratio, allowing it to perform optimally with 92-octane while saving money. For my daily commute, using 92-octane saves me a few cents per liter, adding up to significant fuel savings over a year. Occasionally trying 95-octane won't harm the car, but long-term use is simply wasteful. I once accidentally filled up with 95-octane and noticed slightly smoother starts, but highway fuel efficiency remained unchanged. Bottom line: stick to the manual's recommendation and don't fall for gas station upsells.

I'm someone who enjoys delving into automotive technology. The compression ratio of the Yidong Plus engine is typically around 10, which is a standard design, and it's perfectly adequate to use 92-octane gasoline. The octane rating corresponds to anti-knock performance; 92-octane has good anti-knock properties and is more cost-effective. While 95-octane has a higher rating and theoretically can reduce knocking under extreme conditions, such scenarios are almost never encountered in everyday driving with the Yidong Plus. The only advantage of using 95-octane is that the power output might be slightly smoother, but the difference is negligible and not wallet-friendly. I recommend sticking with 92-octane and regularly checking the spark plugs and fuel system.

As a new owner of the Yidong Plus, I saw the manual specifies 92-octane gasoline, so I used it directly without any worries. 95-octane is more expensive, and it would be a waste if the engine isn't designed for it. I asked the 4S store, and they confirmed that all Yidong Plus models are compatible with 92-octane fuel, so there's no need to overthink it. It's been working perfectly fine with no issues—just make sure not to pick the wrong octane at the pump. Saves money and gives peace of mind.

I prioritize daily expenses and environmental protection, and using 92-octane fuel in the Yidong Plus is the most cost-effective. Although 95-octane offers slightly better fuel efficiency, its higher price means that 92-octane saves more on fuel costs in the long run, reducing expenses. It also lowers carbon emissions because standard gasoline production is more eco-friendly. My experience shows that 92-octane fully meets the requirements, making an upgrade unnecessary.

I've been maintaining my Yidong Plus strictly according to the manual, which requires 92-octane gasoline, so I've been consistently using it. While 95-octane might offer a slight performance boost, the engine isn't designed or optimized for it, and long-term use could slightly increase the risk of carbon buildup. I recommend regularly refueling to keep the tank clean and avoiding mixing different octane ratings. It's both cost-effective and good for the car's health.
