Cleaning the intake valve of a car saves fuel or costs oil.

Of course, it saves fuel after cleaning.

It reduces other consumption.

Let's talk about how to save fuel in our car.

Clean up the engine carbon deposit, which is the bane of increasing fuel consumption.

Because the pistons of the engine do not work synchronously, after flameout, the intake valves of some cylinders cannot be completely closed, and unburned fuel vapor will be oxidized and attached to the valves, forming sponge carbon deposits over time.

This will affect the dilution of mixture concentration, incomplete engine combustion and increased fuel consumption.

Replace the clutch plate in time when shifting manually. If it is found that the vehicle will shake obviously when it starts normally, it will not go without adding some oil, which is a precursor to obvious clutch wear and slippage.

On the other hand, we can also observe the number of revolutions. For example, when 100km/h was running, the number of revolutions was 3,000, and now it is about 3,300-3,500, which can be understood as the loss of engine speed, and it is necessary to refuel to compensate for the speed, which will also lead to an increase in fuel consumption.
