Can the 2021 Tharu always use 92 octane gasoline?

The 2021 Tharu cannot use 92 octane gasoline. According to official recommendations, the Tharu should use 95 octane gasoline. You can check the vehicle's user manual for clear instructions or look for the fuel standard label inside the fuel tank cap. Using 92 octane gasoline in the Tharu may cause severe engine carbon deposits, reduced power, shortened engine lifespan, and other issues that affect driving safety. The main differences between 92 and 95 octane gasoline lie in their octane ratings, anti-knock properties, and prices. 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline consists of 95% isooctane and 5% n-heptane. Gasolines with different octane ratings have varying octane values. The higher the octane rating, the higher the octane value, and the better the anti-knock performance. 95 octane gasoline is more expensive than 92 octane gasoline, primarily due to its higher proportion of isooctane. Fuel usage precautions: Maintain consistent use of one type of fuel. Mixing different fuels can be harmful to the engine and fuel system. Each engine undergoes comprehensive evaluation before leaving the factory, and based on its performance characteristics, the required anti-knock properties are determined, specifying which octane rating should be used.
From a technical perspective, having driven many Volkswagen models, I can say the 2021 Tharu's engine design has high fuel octane requirements, with the manual recommending 95-octane gasoline as the primary choice. Using 92-octane fuel with lower octane ratings can easily cause engine knocking issues—where premature piston ignition leads to abnormal vibrations. Over time, this increases carbon deposits and spark plug erosion, affecting power output. Occasionally using 92-octane might suffice for city commuting, but long-term use will definitely harm engine longevity and lead to costlier repairs. It's advisable to regularly inspect the fuel system and use specialized cleaners to protect fuel injectors, ensuring your car remains in stable condition.
As someone who prioritizes economy, I thought saving money by using 92-octane gasoline might seem cheaper, but it's actually not cost-effective for the 2021 Tharu. In the short term, it saves a few cents per kilometer, but using inappropriate fuel can increase fuel consumption by 5-10%. The higher risk of engine knocking could double repair costs. After a month of testing with 92-octane fuel, I noticed sluggish acceleration and had to perform maintenance earlier. Sticking with the recommended 95-octane gasoline turns out to be more economical overall, especially when the price difference is minimal. Avoiding small savings that could damage major components is wise, and using fuel additives can extend the lifespan of engine parts.
Sharing my experience briefly, as an owner of the 2021 Tharu, the manual recommends 95-octane fuel. I've tried 92-octane a few times with no obvious issues in city driving, but noticed weaker power during uphill climbs. Consulted experienced driver friends who said occasional mixing with 92 is acceptable, just don't make it a habit. For long-distance or highway trips, sticking to 95-octane is safer to avoid increased engine noise over time. Remember to change the air filter regularly and maintain fuel system cleanliness.
