Does overfilling the gear oil in the Jog i have any impact?

Overfilling the gear oil in the Jog i does have an impact. Excessive gear oil can increase the operating resistance of the gears, leading to higher fuel consumption. It can also cause the transmission temperature to rise excessively, making the gear oil more prone to deterioration. When the gear oil temperature increases, the pressure inside the transmission also rises, which may result in oil leaks (at joints, axle seals, etc.). The role of gear oil: Gear oil primarily refers to the lubricant used in transmissions and rear axles. It differs from engine oil in terms of usage conditions, composition, and performance characteristics. Gear oil mainly functions to lubricate gears and bearings, prevent wear and corrosion, and assist in dissipating heat from the gears. The importance of gear oil: Automotive gear oil is used in gear transmission mechanisms such as steering gears, transmissions, and drive axles. Due to the high surface pressure during gear operation, gear oil plays a crucial role in lubricating gears, reducing wear, cooling, dissipating heat, preventing corrosion and rust, cleaning, and minimizing gear surface impact and noise.

Is the Fuel Consumption Data from MIIT Reliable?

The fuel consumption data released by the Ministry of Industry and Information Technology (MIIT) is relatively reliable, but it is only theoretical data and can only serve as a reference. Below is some relevant information about fuel consumption: 1. Fuel consumption per 100 kilometers: This refers to the amount of fuel a vehicle consumes when driving a certain distance at a specified speed. It is a theoretical indicator for vehicles. Manufacturers measure this value in an objective environment using a dynamometer installed on the vehicle's chassis, converting it into speed parameters, and then calculating the theoretical experimental fuel consumption per 100 kilometers for the model at specified speeds. 2. Road condition fuel consumption: This is a fuel indicator calculated based on repeated tests where the vehicle is driven on specified roads at prescribed speeds and times. It is also known as multi-condition road cycle fuel consumption. The standard specifies that each cycle includes various driving conditions, and records the driving conditions based on indicators such as specified gear-shifting times, parking durations, driving speeds, acceleration, braking, and deceleration for each cycle. The values obtained through this method are closer to actual usage.

Is it allowed to cross the solid line when making a U-turn?

It is not allowed to cross the solid line when making a left-turn U-turn. Generally, on major traffic routes, double yellow solid lines are painted in the middle of the lanes, and vehicles crossing these double yellow lines will be fined and penalized with points. This is because at such road intersections, there is a high volume of traffic, and failing to strictly adhere to traffic rules can easily lead to accidents and cause road congestion. The relevant details are as follows: Conditions under which U-turns are allowed: Presence of U-turn signal or sign: At intersections with U-turn signals, a U-turn is permitted when the U-turn signal is green; if there is a U-turn sign or a lane marking indicating U-turns is present, a U-turn can be made ensuring the safety of oneself and others. No U-turn sign but left turns are allowed (no prohibition of U-turn signs or markings): Vehicles can make a U-turn at intersections where left turns are permitted and there are no signs or markings prohibiting U-turns. It is important to note that the vehicle must proceed according to the left-turn lane signal without affecting the normal flow of other vehicles. If making a U-turn at an intersection with a left-turn waiting area, the vehicle can first enter the waiting area when the straight signal is green and wait until the left-turn signal turns green to make the U-turn. U-turns are allowed at dashed lines: Whether it is a white or yellow dashed line, U-turns are permitted. If it is a double yellow line with one solid and one dashed, check if your side is the dashed line; if so, a U-turn is allowed safely; if it is a solid line, U-turns are not permitted. At intersections with double yellow lines (one solid and one dashed), U-turns can be made on the dashed line side, but the vehicle must not cross the stop line ahead. U-turns are allowed at yellow grid lines: Parking is prohibited in yellow grid line areas, but as long as there is no central barrier, a U-turn can be made here after yielding to normally moving vehicles.

What is the coverage of the new car three guarantees?

New car three guarantees coverage is as follows: 1. Return or exchange: If the same fault is repaired more than 5 times, the car can be exchanged. Within the three guarantees validity period (the three guarantees validity period is 2 years or 50,000 kilometers, whichever comes first), if the cumulative repair time of the car exceeds 35 days, or the cumulative repairs for the same product quality problem exceed 5 times, the consumer can exchange the car. Within 60 days from the date the seller issues the purchase invoice or within 3,000 kilometers of driving (whichever comes first), if the family car product experiences steering system failure, braking system failure, body cracking, or fuel leakage, the consumer can choose to replace the family car product or return it, and the seller shall be responsible for free replacement or return. Within the three guarantees validity period, if serious safety performance faults have been repaired twice cumulatively and the serious safety performance faults have not been eliminated or new serious safety performance faults occur; if the engine or transmission has been replaced twice cumulatively, or the same major component of the engine or transmission has been replaced twice cumulatively due to quality problems and still cannot be used normally (the replacement counts for the engine, transmission, and their major components are not duplicated); if the same major component of the steering system, braking system, suspension system, front/rear axle, or body has been replaced twice cumulatively due to quality problems and still cannot be used normally, the consumer can choose to replace or return the car, and the seller shall be responsible for replacement or return. If the family car product meets the conditions for replacement, but the seller does not have the same model of a different brand or a family car product with a configuration not lower than the original car to offer the consumer for replacement, the consumer can choose to return the car, and the seller shall be responsible for returning the car to the consumer. 2. If the repair exceeds 5 days, the owner has the right to use a spare car: During the warranty period, if the family car product has quality problems, the consumer can have it repaired for free by the repairer with the three guarantees certificate, including labor and material costs.

What is the height limit for tow trucks?

Towing height limit is 4 meters to 4.2 meters. For heavy and medium-duty trucks and semi-trailers, the height from the ground must not exceed 4 meters, and for vehicles carrying containers, the height must not exceed 4.2 meters. Tow Truck: The full name of a tow truck is a road clearance vehicle, also known as a tow truck, road rescue vehicle, or towing vehicle. It has multiple functions such as lifting, pulling, and towing. Tow trucks are mainly used for road breakdown vehicles, urban traffic violation vehicles, and emergency rescue operations. Tow trucks are categorized into: integrated towing and lifting type, separate towing and lifting type, one-tow-one type, flatbed one-tow-two type, multi-functional tow trucks, and hydraulic automatic clamping type. Specific Uses: A tow truck is a specialized vehicle equipped with road emergency operation equipment. Since breakdowns and accidents are inevitable when vehicles are on the road, especially on highways, such incidents often occur. The task of a tow truck is to promptly remove the broken-down or accident vehicle from the scene to ensure smooth traffic flow. Therefore, tow trucks are also called road emergency vehicles. With the increase in high-grade roads and vehicles in use, tow trucks have also developed. They are mainly used for road breakdown vehicles, urban traffic violation vehicles, and emergency rescue operations.

What is Mineral Oil?

Mineral oil is a type of engine oil, which refers to lubricating oil whose base oil raw material is mineral oil, not synthetic oil. The following is a detailed introduction to the classification standards of engine oil grades: 1. Types of engine oil: Engine oil grades are divided into gasoline type, diesel type, and gasoline-diesel universal type: Those starting with the letter "S" represent oil for gasoline engines, with specifications including API SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN; Those starting with the letter "C" represent oil for diesel engines, with specifications including API CA, CB, CC, CD, CE, CF, CF-2, CF-4, CG-4, CH-4, CI-4. If both are present, such as SM/CF, it indicates that the oil is a gasoline-diesel universal type. 2. Meaning of the letters: The further back the letter after S or C, the higher the quality grade of the oil, the more stable the performance, and the higher the oil grade. Currently, the market also divides engine oil into three categories: mineral oil, semi-synthetic oil, and synthetic oil. The corresponding oil grades are SA to SJ for mineral oil, SJ and SL for semi-synthetic oil, and SM and SN for fully synthetic oil. In addition to the oil grade identification, some engine oil packaging will have the SAE mark. SAE is the abbreviation of the Society of Automotive Engineers, which formulates the standard viscosity values for engine oil, such as 5W-30.
