Generally, it should be replaced every 3 to 4 years, or when the mileage reaches 60,000 to 80,000 kilometers. Gear oil and transmission oil: There is no difference between gear oil and transmission oil. Transmission oil and gear oil are usually the same, with corresponding models used according to different vehicle types. Manual transmission vehicles mainly use it for gear lubrication, while automatic transmission vehicles primarily use it for transmission lubrication and power transmission. Introduction to gear oil: Gear oil is mainly composed of petroleum lubricating base oil or synthetic lubricating oil, with the addition of extreme pressure anti-wear agents and oiliness agents. It is an important lubricating oil used in various gear transmission devices to prevent tooth surface wear, scuffing, sintering, etc., thereby extending their service life and improving power transmission efficiency.

What are the effects of keeping the exhaust brake on for a long time on a vehicle?

Keeping the exhaust brake on for a long time has no effect on the vehicle. The correct usage of the exhaust brake is as follows: 1. The exhaust brake cannot replace the service brake for emergency braking or be used as a parking brake, but it can be used simultaneously with the service brake; 2. When the exhaust brake is in use, the accelerator pedal should be at the zero position, and the fuel injector stops injecting fuel. Pressing the accelerator or clutch pedal will automatically turn off the exhaust brake to prevent engine stalling when stopping and exhaust brake activation during fuel injection; 3. Do not use the exhaust brake on icy or slippery roads to avoid driving skids and slippage; 4. The braking power of the engine exhaust brake depends on the engine speed. To ensure optimal braking performance, select the appropriate vehicle gear when using the exhaust brake on long downhill slopes.

How to Remove Cigarette Smoke Smell from a Car?

Methods to remove cigarette smoke smell from a car are as follows: 1. Initial thorough cleaning of the car interior. First, use a vacuum cleaner to remove dust from the carpets, then clean the carpets with a carpet cleaner. If cleaning the carpets seems too troublesome, simply vacuuming them can also be quite effective. 2. Most cleaning agents have strong odor-removing capabilities. Spray them on all visible surfaces, then use a soft-bristled brush to spread the cleaning agent evenly. 3. Baking soda can absorb odors inside the car. Sprinkle baking soda on all porous surfaces inside the car, use a soft-bristled brush to work it in, and let it sit for several hours or even a full day. The longer it sits, the better the effect, as the baking soda gradually neutralizes the odors in the car.

What is the reason for the car's oil pressure warning light to illuminate?

The car's oil pressure warning light is the engine oil pressure indicator. The oil light illuminates due to low oil pressure. Causes of low oil pressure include: 1. The oil level is too low. 2. The oil passage is blocked. 3. The oil has deteriorated. 4. The oil pressure sensor is faulty. Additional information: 1. The oil filter should be replaced every time the oil is changed, and the filter must be tightened to the specified torque during replacement. If the oil filter is not tightened properly, it can cause oil leakage, which may also lead to low oil pressure. 2. Low oil pressure can result in poor lubrication and abnormal wear of internal engine components. Once the oil pressure warning light comes on, the engine should be shut off as soon as possible, and assistance should be called to avoid further damage.
