Is it mandatory to use 95 octane gasoline for the Bora 1.4T?

It is not mandatory to use 95 octane gasoline for the Bora 1.4T, but it is recommended to use 95 octane gasoline. Minimum octane rating: The octane rating indicated on the car is the minimum safe rating for combustion. However, the minimum rating is by no means the gasoline with the best fuel efficiency ratio. Cylinder compression ratio: Generally, if the compression ratio is greater than or equal to 10:1, gasoline with an octane rating of 95 or higher is required. Additionally, when an engine is developed, there is a designed gasoline octane rating, and all designs are based on this rating. Engines with a 10:1 compression ratio are usually developed using 95 octane gasoline. At this rating, the optimal combustion efficiency can be achieved.
In my opinion, the Bora's 1.4T engine is indeed designed to recommend using 95-octane gasoline because it's a turbocharged engine with higher requirements for fuel's anti-knock performance. Using 92-octane fuel may cause engine knocking, power reduction, or long-term damage to internal components, increasing maintenance risks. I've driven a similar car myself and always insisted on using 95-octane, finding the engine runs smoother and fuel consumption is more economical. Additionally, I suggest checking the owner's manual, which clearly states the fuel octane requirement, usually RON 95 or above. To protect your car in the long run and avoid unexpected expenses, it's best to develop the habit of using 95-octane, especially when frequently driving on highways, as it provides better power response. In short, saving money might feel good temporarily, but repairs will cost more.
From an economic perspective, I believe this issue warrants discussion. The Volkswagen Bora 1.4T officially recommends using 95-octane gasoline. While occasionally filling up with 92-octane for short trips might not cause immediate problems, frequent use of lower-grade fuel can lead to increased engine carbon deposits, incomplete combustion, and even shortened engine lifespan. I've done the math - 95-octane costs about 1 yuan more per liter, but its higher thermal efficiency actually results in slightly better fuel economy, making it more cost-effective in the long run. If problems do occur, repairing the turbo system could cost thousands, which simply isn't worth the risk. It's best to follow the manual's recommendations rather than cutting corners. Personally, I'd advise playing it safe with this vehicle - using 95-octane ensures stable performance and peace of mind.
