The Borgward BX5 uses 95-octane gasoline. The octane rating of gasoline represents only a parameter of its anti-knock performance, with higher ratings indicating better anti-knock performance, and has no relation to purity. Below are some relevant details about the Borgward BX5: 1. Dimensions: The Borgward BX5 has a length, width, and height of 4490mm, 1877mm, and 1675mm respectively, a wheelbase of 2685mm, a fuel tank capacity of 60L, a minimum ground clearance of 186mm, a maximum horsepower of 150, and a maximum power of 110 kW. 2. Related configurations: The Borgward BX5 is equipped with a 6-speed automatic transmission, front MacPherson independent suspension, rear multi-link independent suspension, front-wheel drive, an 8.0-inch touch LCD screen, Bluetooth, a trip computer display, and supports mobile phone connectivity.

I've been driving this car for three years. The sticker inside the fuel filler cap clearly states unleaded gasoline with an octane rating of 92 or above. The manual says 92 is sufficient, so don't be fooled by gas station attendants into wasting money on 95. I usually fill up with Sinopec 92-octane, and during maintenance, the mechanic checked the engine condition and said carbon buildup is well controlled. The fuel tank cap release switch is located below the left side of the driver's seat—remember to turn off the engine before refueling. On the highway, a full tank can last for 600 kilometers, and when gas prices rise, it works out to just over 6 cents per kilometer.

Last week, I accompanied a friend to repair his Borgward BX5. The garage owner held up the fuel nozzle and said, '92-octane gasoline is more than enough, and turbocharged engines don’t need special treatment.' He did remind us to replace the fuel filter every 30,000 kilometers, otherwise, impurities could clog the fuel lines and damage the car. He casually showed us a dismantled old BX5—its fuel injectors, which had long been running on 92-octane, were cleaner than some German cars. Borgward’s powertrain is indeed quite durable.

Just picked up the car and specifically checked the owner's manual. Chapter 7 clearly states that 92-octane (RON) is recommended. The fuel tank capacity is 55 liters, with about 10 liters remaining when the fuel light comes on. Tested mixing 92 and 95 with no issues, but it's unnecessary. Once at a highway service station, only 95 was available, and fuel consumption increased by 0.3. The 4S technical director said the gasoline grade only differs in anti-knock performance, and using a higher grade is like drinking mineral water instead of milk tea with 92-octane money.

The engine with a compression ratio of 9.5:1 is designed to run on lower-grade fuel. I've seen the same engine model in Germany listed for diesel vehicles. When refueling, be especially careful not to use gasoline with ethanol content exceeding 10%. Friends in northern regions should pay extra attention to fuel quality during winter. Last year, a fellow car owner experienced injector crystallization after using water-contaminated gasoline, resulting in a thousand-yuan bill for fuel system cleaning.
