Fuel additives can be find at the petrol stations; are they efficient?
Fuel additives can be useful if used properly. It is necessary to carefully read the additive manufacturer's instructions, check the type of vehicle for which they are intended, check for restrictions on use by the car’s manufacturer, and adhere to the recommended method of application and dosage. Any improper use or application of inadequate additives can cause more harm than good. If properly applied, additives will not have any adverse effects, but depending on the condition of the engine, the improvement may be less than expected or there might not even be any.
