Does gasoline with high ethanol content have the function of cleaning engine carbon deposit?

It may help, but the effect may not be good. Just like the health care products that people eat, the principle that treating diseases can't help relieve pain is helpful. To solve the problem of carbon deposition, we must first understand the causes of carbon deposition. After the unburned gasoline in the cylinder volatilizes, the residual glue and wax will deposit on the cylinder wall and valve. If it is not cleaned in time, it will accumulate thicker and thicker, and it will become carbon deposit after repeated heating. One way to remove carbon deposit is that the carbon deposit is not too serious, so the disassembly-free cleaning method is adopted and special liquid is added for cleaning. The other is serious carbon deposition, so the method of uncovering the cylinder head to clean the valve and cylinder wall should be adopted. One is to take some preventive and remedial measures to minimize carbon deposition, 1, and use clean fuel that meets the label; 2. Cultivate good driving habits and shift gears by hand over 2000 rpm; 3. Raise the speed at regular intervals, so that the engine can run at high speed to remove slight carbon deposit.
