Do you need to change the oil after cleaning the carbon deposit?

You don't need to change the oil. Cleaning up the carbon deposit will not affect the oil.

The carbon deposit cleaning project includes the following aspects

1. Clean the throttle:

Take off the engine decorative cover, remove the throttle, clean it with carburetor cleaner, dry it with cotton cloth and install it. Under normal circumstances, the cleaning cycle of the throttle valve is 20000 km.

2. Remove the carbon deposit inside the engine:

Open the oil cover, pour the whole tank of cleaning agent (mixed with old oil), cover the oil cover, ignite the engine at idle speed 10 minutes, and then turn off the engine. Clean the carbon deposit inside the engine. This cleaner can dissolve the deposits such as sludge, colloid, moisture and metal debris inside the engine, reduce the pollution of new engine oil and prolong the service life of the engine. Its cleaning cycle is generally 30,000 kilometers, and the cleaning method of carbon deposit in the engine is also very simple. Before maintenance, just add a bottle of engine internal cleaning agent to the oil port, idle for about 10 minutes, and then immediately maintain and replace the oil filter. Car owners and friends can buy engine internal cleaning agents online.

3. Remove the carbon deposit in the oil circuit:

Before refueling, add the whole bottle of fuel additive to the fuel tank. How many liters is there in the car tank? Usually, a bottle of fuel additive is used in a 50-80 liter fuel tank. Cleaning the carbon deposit in the oil circuit includes cleaning the fuel injector, combustion chamber, spark plug, throttle and other parts. The purpose is to solve the intractable diseases such as insufficient horsepower, high oil consumption, wheezing, poor acceleration or difficult start-up caused by carbon deposit, colloid and dirt in the oil system. Cleaning these does not need any disassembly, as long as special cleaning fuel additives are added to the automobile fuel tank regularly, good cleaning effect can be achieved. General fuel additives are divided into three types: clean type, maintenance type and octane number improvement type.

4. Remove the carbon deposit in the air intake system:

Buy a bottle of cleaning agent for air intake system, pour it into the liquid storage tank of special cleaning equipment, connect the air intake system, and suck the cleaning agent into the air intake by vacuum to achieve the purpose of cleaning. Cleaning the carbon deposit in the intake system mainly refers to cleaning the carbon deposit in the intake and intake manifold. Its purpose is to remove carbon deposits in the intake system, increase intake flow and speed, and reduce engine jitter and idle instability. Generally, 4S shops or repair shops will pump the intake cleaning solution into the intake pipe with hanging bottles, and the cost is quite high.
