Can the Borgward BX5 use 92 octane gasoline?

Borgward BX5 can use 92 octane gasoline. The fuel cap of the Borgward BX5 states "Please refuel with 92/95/93/97 unleaded gasoline, with 95 octane being the recommended fuel." However, it is best to use unleaded gasoline with an octane rating of 95. Here is the relevant introduction: Gasoline grades: The so-called 95 octane gasoline and 92 octane gasoline have no difference in fuel quality. It cannot be assumed that the higher the gasoline grade, the better the gasoline quality. In fact, the main difference between 92 octane gasoline and 95 octane gasoline lies in the octane value. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. Precautions: If the car is equipped with a turbocharged engine, it is recommended to use 95 octane gasoline. If the car is equipped with a naturally aspirated engine, it is recommended to use 92 octane gasoline. The minimum fuel grade required for the engine can be found on the inside of the car's fuel cap, where there are specific instructions. It is recommended to use the fuel grade officially recommended for the car.

I've been driving the Borgward BX5, and the manual clearly states that this car fully supports using 92-octane gasoline. The engine of the Borgward BX5 was designed with China's fuel standards in mind, so 92-octane unleaded gasoline can be used directly without worrying about engine damage. Of course, using 92-octane might slightly affect performance, such as a bit slower acceleration or slightly higher fuel consumption, but it's completely fine for daily city commuting. I usually go for the economical option—it saves quite a bit on fuel costs, and the money saved is enough to upgrade to better engine oil. I recommend checking the spark plugs and fuel system during each maintenance to ensure the fuel isn't adulterated, which will keep the car running smoothly in the long term.

As a veteran driver who has been driving the Borgward BX5 for nearly three years, I find using 92-octane gasoline quite reliable. In our car owner group, we often discuss this topic, and most members use 92-octane without any complaints about engine issues. The Borgward BX5's engine is well-tuned with modest octane requirements, making 92-octane perfectly adequate. If you occasionally feel sluggish acceleration during startup, it might be due to fuel quality variations—simply try a different branded gas station. Cost-saving is a major advantage; 92-octane is significantly cheaper than 95-octane, saving dozens of yuan per month on fuel costs—small savings add up over time. Always choose reputable gas stations and avoid cheap, small-scale fuel vendors to prevent impurities from clogging the fuel injectors.

The Borgward BX5 can run on 92-octane gasoline without issues, which was confirmed at the time of purchase. The engine's compression ratio is moderate, around 9.5, so 92-octane fuel meets the anti-knock requirements. If you use 92-octane, there might be slight noise when climbing hills or at high speeds, but it's not severe as long as maintenance is proper. I make it a habit to check the engine's condition monthly to ensure everything is running smoothly, while also inspecting the fuel tank cap's seal. Using 92-octane long-term is truly hassle-free, especially for budget-conscious families—saving over a hundred yuan on fuel each month, enough for a fun outing with the kids.
