Today, at every major gas station, they offer to fill the tank with both regular gasoline – for example, 95th – and branded gasoline with the same octane rating. “Firm” is usually more expensive, as it contains various additives. The AvtoVzglyad portal tells about the owners of which cars to refuel with exactly such fuel.
To answer the question, you must first understand the drive systems used on motorcycles. Mono-injection was installed on very old machines. Like, for example, Volkswagen Passat B4 or Audi 100. Now such solutions are irrelevant.
Therefore, we will focus on distributed and direct constructions. They are the most common. For example, the first can be seen on the BMW E90 318i. Here the injection does not go into the cylinders, but into the manifold. In the second case, the fuel is supplied under high pressure and more accurately dosed directly to the cylinders. This allows you to both reduce consumption and improve the environmental performance of the car. Both solutions have their drawbacks, which only become apparent over time.
In multi-port injection, the nozzles have large holes and operate at lower pressures. That is, deposits accumulate gradually, and when they accumulate, they begin to cause problems. For example, the engine starts to run erratically when idling.
With direct injection, the holes in the fuel injectors are very small. Due to the high pressure, deposits appear more slowly on it, but it can happen that dirt simply clogs one or more holes. The result is malfunctions and vibrations of the drive unit.
In general, sewage should be removed, and “branded” gasoline, which contains detergent additives, will just help here. They gradually clean the fuel system from carbon deposits and deposits. True, it is necessary to regularly refill such fuel. From once there will be no effect. By the way, “spheres” with a high degree of compression are also sensitive to fuel quality. For example Skyactive units from Mazda.
Finally, you should not lower the octane number, even if the manufacturer does not prohibit it. We do not recommend using the 92nd instead of the 95th. The engine can therefore explode, which will have disastrous consequences. That is, we run all “Chinese” with the “firm”. This will delay the repair of expensive fuel equipment, especially since it is from European manufacturers.
