Methanol gasoline and ethanol gasoline differ in the following ways: Methanol gasoline is cheaper, methanol is an alcohol-based fuel with the lowest density and the least stable usage; Ethanol gasoline is regular gasoline blended with 10% modified ethanol, which costs more than regular gasoline. Methanol gasoline provides more power than ethanol gasoline, but ethanol gasoline has higher fuel consumption. Additional information: 1. Methanol gasoline: Methanol gasoline is a low-carbon energy source that can replace regular gasoline and is specifically designed for use in gasoline internal combustion engine vehicles. It is produced by blending industrial methanol or fuel methanol with denatured alcohol additives and existing national standard gasoline in a certain volume ratio. Methanol gasoline is cheaper, and methanol, as an alcohol-based fuel, has the lowest density and the least stable usage. 2. Ethanol gasoline: Ethanol gasoline is a new alternative energy source formed by mixing fuel ethanol processed from grains and various plant fibers with regular gasoline in a certain proportion. Ethanol gasoline is regular gasoline blended with 10% modified ethanol, which costs more than regular gasoline.

To be honest, I have quite some experience with these two fuels. Methanol gasoline is mainly synthesized from coal or natural gas. Compared to ethanol, it's highly corrosive—my old car's fuel lines rotted years ago, costing me a lot in repairs. Ethanol gasoline, made from fermented corn or sugarcane, feels more eco-friendly but has lower calorific value, resulting in slightly weaker power and possibly a few percent higher fuel consumption. Methanol also tends to cause more engine carbon buildup, which is annoying in the long run, while ethanol gasoline's high hygroscopicity can affect starting in rainy seasons or humid areas. Environmentally, ethanol is renewable and better for carbon reduction, whereas methanol, though clean, involves significant pollution during production. Overall, from a safety perspective, I'd recommend new cars prioritize ethanol gasoline and regularly check the fuel system.

What is the function of variable steering ratio?

Variable steering ratio function can reduce the number of steering wheel turns, achieving better steering performance at low speeds and improving the vehicle's maneuverability. Here are two benefits of the variable steering ratio function: 1. Convenience: The variable steering ratio function allows the steering wheel to be fully turned with just one rotation when the vehicle speed is low, while at higher speeds, it requires one and a half turns as usual to fully turn the steering wheel. 2. Enhanced steering stability: The variable steering ratio adjusts the steering gear ratio based on the vehicle's speed and steering angle. When the vehicle is at low speed or stationary, the steering angle is larger, and the variable steering ratio function provides a smaller steering gear ratio. During high-speed driving or when the steering ratio is small, it provides a larger steering gear ratio, thereby improving the stability of the vehicle during steering.

Is it okay to drive a short distance with a flat tire?

It is not advisable to drive any distance with a flat tire. Here is relevant information about car tires: Function: Car tires are one of the most important components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help absorb shocks during driving, ensuring good ride comfort and smooth operation; they maintain good traction between the wheels and the road; improve the vehicle's traction, braking, and off-road capability; and bear the weight of the car. The critical role tires play in vehicles is increasingly recognized. Classification: By structure, they can be divided into radial tires and bias tires; by tread pattern, they can be categorized into ribbed tires, transverse pattern tires, mixed pattern tires, and off-road pattern tires.

Is it necessary to add fuel additive for a new car?

It is not necessary to add fuel additive for a new car, because the effect of fuel additive is relatively limited, and the fuel at domestic gas stations already contains fuel additive components. Additionally, since a new car's engine has a short service life and operates in good condition, it will not produce carbon deposits. Therefore, car owners do not need to add fuel additive to a new car. Fuel additive, also known as fuel system cleaner, is directly poured into the vehicle's fuel tank and mixed with gasoline when used. The main function of fuel additive is to clean carbon deposits, while also assisting in engine maintenance and cleaning the fuel system. Some special-purpose fuel additives can also improve the anti-knock performance of the fuel.

Is It Illegal to Remove the Seats from a Minivan?

Removing the seats from a minivan is an illegal act, referred to as unauthorized modification or unauthorized change of vehicle usage. Below are the penalties and consequences of removing minivan seats: 1. Penalties: If caught by traffic police for unauthorized removal of minivan rear seats, you will face a fine of 500 yuan. Additionally, removing the rear seats can lead to the mixing of passengers and cargo, which will also incur corresponding penalties from transportation authorities. 2. Consequences: If you remove the rear seats of a minivan without authorization to transport goods, it is highly likely that overloading the vehicle with goods could cause it to exceed weight limits. This increases the risk of rollovers during turns or emergencies, posing significant safety hazards.

What is the maximum speed when passing through a sharp turn?

When a motor vehicle passes through a sharp turn, the maximum speed is 30KM/h. The following are precautions for driving a motor vehicle: Maintain a safe speed: When driving on the road, do not exceed the speed indicated by speed limit signs and markings, always maintain a safe speed, and refuse to speed. Maintain a safe distance: The driver should always maintain a safe longitudinal and lateral distance from other vehicles, drive cautiously, and avoid traffic injuries. Pass intersections with caution: Intersections are places with complex traffic conditions. When approaching an intersection, the driver should slow down, observe the traffic conditions ahead, and pass the intersection carefully after confirming safety.
