Ordinary vehicles are not allowed to be modified by the owner, and installing a roll cage may be considered illegal. Adding a roll cage will inevitably involve altering the original vehicle structure, which introduces more safety risks when done without professional guidance. Below is relevant information: 1. Definition of a Roll Cage: A roll cage is a detachable assembly of steel tubes, typically made from cold-drawn seamless carbon steel pipes that are bent and shaped. During installation, the tubes are connected or welded one by one according to the interior contours of the vehicle. 2. Function of a Roll Cage: The material and torsional resistance of the steel pipes used in a roll cage are determined based on the vehicle's weight, generally designed to withstand impacts exceeding twice the vehicle's weight. 3. Requirements for a Roll Cage: A proper roll cage must consider factors such as joint connections, angles and design, material quality, and craftsmanship to effectively protect the vehicle and occupants in the event of an accident. Homemade roll cages may appear sturdy but often fall short in actual performance. There have been numerous reports of drivers being injured or killed by punctures from twisted vehicle frames during accidents. Therefore, it is advisable to avoid installing a roll cage on your own, as it is unnecessary for household vehicles.

Is it necessary to add fuel additive to cars?

It is not mandatory to add fuel additive to cars. The purpose of fuel additive is to solve the carbon deposit problem in the fuel system of electronically controlled fuel injection vehicles, quickly restore the optimal working condition of the engine, and compensate for some defects in gasoline properties while endowing gasoline with new excellent characteristics, such as improving atomization, reducing wear, protecting the engine, and lowering emissions. The functions of fuel additive include: 1. Removing carbon deposits in the car; 2. Reducing abnormal wear of the engine; 3. Improving atomization efficiency; 4. Lowering vehicle emissions; 5. Extending the service life of the car engine. The correct way to use fuel additive is: add the fuel additive before refueling, then add gasoline, so that the pre-added fuel additive can be fully and evenly mixed under the impact of gasoline injection, thus achieving the ideal usage effect.
