There is oil in the accelerator. What is the reason?

There is oil at the throttle, mostly a turbocharged engine. 1. Most of the engine oil at the throttle is brought in by the engine oil at the turbocharger through the intake air. Less oil in the throttle has little effect, and a small amount of oil is normal. If there is too much oil at the throttle, the lubrication and sealing performance of turbocharger oil should be considered. Turbocharged oil combustion is the failure of sealing performance of turbocharged oil lubrication system. 2. It is normal to have a small amount of engine oil at the throttle of supercharged engine. Lubrication of supercharger kit of supercharged engine depends on oil and gas in engine intake (oil and gas in crankcase). There is too much oil at the throttle of supercharged engine, which may be an obstacle to the exhaust gas circulation system. 3. Too much throttle oil may be the fault of the engine crankcase exhaust circulation system, the exhaust circulation check valve is damaged, and a small amount of throttle oil is normal, but too much oil is abnormal, which may be the fault of an engine accessory, so it should be detected and handled in time. 4. How to judge whether the throttle oil is too much or normal? Use the simplest method to judge whether the throttle leaks too much oil. When there is oil in the throttle, remember the mileage of the car and calculate the remaining oil by comparing the maintenance cycle (the fuel consumption of 5,000 kilometers is normal, and the fuel consumption of 5,000 kilometers is generally less than half a liter). 5. The problem of burning engine oil in cars. In addition, the problem of burning engine oil is complicated and involves many parts, which should be considered comprehensively.
