After the oil is added, the engine is still uphill or weak

If the car is weak after maintenance, it is estimated that it has something to do with too much oil filling, if there is such a fault phenomenon before, then you should check whether the three-way catalytic is blocked, whether the spark plug, cylinder wire, ignition coil is a problem, check whether the cylinder pressure is normal. However, it is best to go to the after-sales service or repair shop for a comprehensive and systematic inspection [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello. If the oil is not too much, there is no power to break the road! Then it is possible that the pressure of the gasoline pump is insufficient, resulting in no power when the load is high!

In addition, if the throttle valve is too early, the air intake will not be enough, and the acceleration will be weak. I hope it can help you, I wish you a happy car [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

In this case, you mainly check the engine's oil supply system, which may not necessarily be the problem of adding too much oil.

Hello. It is possible that it is not a problem with the oil, check the throttle, spark plug. Hope it helps.

Hello, after adding more oil, the excess oil will enter the cylinder to participate in combustion, which will affect the engine power and damage the three-way catalysis, so it is recommended to clean the three-way catalysis after releasing the excess oil to avoid the three-way catalysis due to excessive carbon deposition resulting in poor exhaust and insufficient power, and even leading to complete damage to the three-way catalysis. For more car knowledge, please put in the answer of liking ****, I hope ours can solve your problem, I wish you a happy car! [Car questions, ask the car master.]

In this case, it is recommended to check other parts, it may not be a problem with the engine oil, I hope mine can help you.

"Engine oil" is a necessary lubricant to ensure the normal operation of the engine, its specific role is to lubricate metal parts, reduce the friction between parts, take away the huge heat generated by the engine when doing work, clean the fine metal debris produced after wear, as well as sealing, shock absorption, rust prevention and other functions. However, when filling the oil, it should be noted that the amount of oil should not be too much or too little, and should be between the "low" and "full" positions of the dipstick.

Changing the oil by yourself needs to pay attention to the following points.

1. When it is almost full, you should wait for about a minute after stopping refueling to let the oil flow to the oil pan and then measure, if you just stop refueling to measure, the oil has not flowed to the oil pan, and the measured value is smaller than the actual value, which is also the reason why many friends change the oil by themselves and often add more.

2. The accurate timing of measuring the oil allowance: wait for about 5 minutes after the car is warmed up to allow the oil to fully flow back to the oil pan and then measure. Because there is no oil in the lubrication part when the car is cold, almost all the oil is in the oil pan, and the measured value is low at this time, because after the car starts, a part of the oil will adhere to the lubrication parts of the engine, and the actual oil volume in the oil pan is low.

Because too much engine oil will increase the running resistance of the car, resulting in the car sinking, stuffy, increased noise, weakness and other adverse effects.

In addition, too much engine oil is easy to rise in working temperature and is more likely to deteriorate, which makes the protective performance of automobile oil worse; Too much oil can create bubbles when the parts are running, and the bubbles can get into the lubrication or hydraulic parts, increasing wear and reducing performance.

The oil scale accurately limits the position of the oil. No, you can't add more.

Too much oil can hinder the movement of the crank linkage and consume some of the power.

You want the crankshaft to rotate at least a few hundred times per minute, and several thousand times at high speeds, and each revolution has to consume the corresponding power. In the end, the engine died, that's for sure. Hope it helps.

There is a limit to the amount of everything, not the more the better, but the right amount.

The solution can be determined based on the following reasons:1. If the quality of the oil is poor, you can add gasoline with a suitable number or ***.

2.Due to the high level of carbon deposits, the valve can be cleaned. 3.

If the ignition coil is damaged, it can be replaced. 4.If the fuel filter is too dirty, it can be cleaned.

5.If the gasoline pump is damaged, the oil pump can be replaced. 6.

If the three-way catalytic converter is clogged, it can be cleaned.

The details are as follows:1The quality of the oil is poor.

When there are too many impurities or too much moisture in the fuel, it naturally leads to a lack of power. Moreover, inferior fuel can easily lead to the blockage of small holes or filtration functions such as oil pump filters, gasoline filters, and fuel injectors, resulting in poor oil supply and reduced engine function.

2.The problem of carbon deposits is serious. Excessive carbon deposition in the throttle and intake pipe leads to insufficient gas intake, insufficient gasoline combustion, and natural power failure, which increases fuel consumption to a certain extent.

The nozzle is clogged, resulting in poor fuel atomization, or no fuel injection at all. This results in a lack of cylinders, which reduces the power output of the engine.

3.The ignition coil is damaged, the ignition coil is damaged, a cylinder cannot be ignited to work normally, the lack of cylinder power does not beat the imitation foot, accompanied by engine shaking. If the ignition coil is damaged, it should be replaced in time.

4.The gasoline filter is too dirty. If the fuel filter is not replaced for a long time, the gas filter will not be cleaned. If it's severe, the gas filter will clog. A common phenomenon is that cars tend to stall and often catch fire.

5.The gasoline pump is damaged, the oil pump is damaged, and the oil pump is not working properly, resulting in insufficient pumping, which will eventually lead to insufficient engine fuel injection, and the engine output power will decrease, resulting in insufficient power of the car.

6.Three-way catalytic blockage, the common phenomenon of three-way catalytic problems is that the engine fault light is on, the accelerator pedal is pressed to the end only to hear the engine sound, and the vehicle accelerates slowly.

Millions of car purchase subsidies.

There are two cases in which the engine speed does not change significantly or does not decrease when going downhill: one is a car with automatic transmission, and there is no neutral gear when going downhill; The second is a car with manual transmission, which slides in gear when going downhill.

We know that the power of a car is provided by the engine. When going downhill, the power transmission is not disengaged, and the engine speed is balanced with the speed of the car, and it can maintain a uniform speed without refueling. When the slope of the downhill slope is large, the balance between the speed of the engine and the speed of the vehicle is broken, and the speed of the vehicle is greater than the speed required by the engine, and the gears of the gearbox will drag the engine instead, so that the speed of the engine increases.

If you hit neutral at this point, the revs will drop down quickly.

The engine brakes intelligently and does not inject fuel. It's okay.

That's because you're hanging in the file

Check the oil scale when you are cold down.

Dear, hello, I am happy to serve you to answer, I am a master of car problem solving, the problem you consulted I Sengao judgment made the following changes: Reasons: 1. Fuel injector is blocked, oil pipe leakage, gasoline pump power is reduced, and gasoline filter is blocked; 2. Air filter, throttle and other components are blocked or have problems, resulting in insufficient air intake; 3. Spark plug ignition bad reading hall; 4. At least one cylinder of the engine is running abnormally or stalling.
