Is it useful to clean the throttle with expensive oil?

It won't be particularly obvious, it will save a little oil. Cleaning the throttle will save fuel. Idle instability is a common phenomenon in the early stage after cleaning, because the computer has an adaptation process, the opening and closing of the throttle will also increase, and the air intake will also increase, but the computer will be fine after adaptation.

There are several main reasons for automobile fuel consumption:

1, driver's technical level: unreasonable shift during driving, excessive braking, artificially increasing engine power loss. At the same time, braking too much will increase the number of starts, because the fuel consumption rate at the start is very high. Low temperature driving: The automobile requires the engine to run at normal temperature (80℃ to 90℃). If the engine runs without preheating after starting, the engine will be in a low temperature state, which will cause poor atomization of the mixture and incomplete combustion.

2. carburetor. The oil level in carburetor float chamber is too high; The air filter is too dirty and the carburetor air hole is too dirty; In the long-term use of carburetor, the oil hole is enlarged by fuel; Idle speed adjustment is too high; The semi-balance hole in the float chamber is blocked, resulting in siphon and other phenomena.

3. Valve mechanism. In the valve train, the valve clearance is too large or too small to achieve the purpose of sufficient intake and clean exhaust. At the same time, the valve spring is too soft, and the valve and the valve port are ablated, which makes the valve not reach the ideal sealing degree and reduces the cylinder pressure and engine power.
