Methanol gasoline has a lower price and belongs to alcohol-based fuel, with the lowest density and the least stable usage; ethanol gasoline is made by adding 10% modified ethanol to regular gasoline, and its cost is higher than that of regular gasoline. Methanol gasoline provides more power than ethanol gasoline, while ethanol gasoline has higher fuel consumption. More details are as follows: Methanol gasoline: Methanol gasoline is a low-carbon energy source that can replace regular gasoline and is specifically used as automotive fuel for 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. Ethanol gasoline: Ethanol gasoline is a new alternative energy source formed by blending fuel ethanol processed from grains and various plant fibers with regular gasoline in a certain proportion.

As a car enthusiast, I often research different fuel options. Methanol gasoline is made from coal or natural gas, with low cost but low energy density, making the car feel underpowered and resulting in higher fuel consumption. Ethanol gasoline is extracted from plants like corn, being more environmentally friendly and renewable, with moderate energy density, and E10 blends are common in North America. The key issue is corrosiveness: methanol strongly corrodes engine components like fuel lines, easily damaging the car, while ethanol is less corrosive. In cold winter starts, methanol has good anti-freeze properties but can absorb moisture, leading to fuel mixing issues, whereas ethanol handles this better but requires precautions against water. I recommend upgrading engine components if using methanol, otherwise, long-term damage can be significant.

Is there a big difference between spark plug heat range 6 and 7?

There is a significant difference between spark plug heat range 6 and 7. Spark plug heat ranges are divided into nine levels, with 1~3 being low heat range, 4~6 being medium heat range, and 7~9 being high heat range. Therefore, spark plug heat range 6 belongs to the medium heat type, while heat range 7 belongs to the high heat type. Effects of changing spark plugs: 1. Decreasing the spark plug heat range: When decreasing the spark plug heat range, incomplete combustion of the air-fuel mixture may occur, leading to symptoms such as insufficient power. Additionally, inadequate heat dissipation may cause the spark plug to overheat, potentially resulting in phenomena like detonation. 2. Increasing the spark plug heat range: When increasing the spark plug heat range, the heat dissipation capability improves, causing the spark plug temperature to drop faster. However, this may lead to carbon buildup on the ignition tip, which can cause electrical leakage and prevent the spark plug from firing properly.

What Causes the Car Tire Pressure Warning?

The car tire pressure warning is triggered when the pressure in the four tires falls outside the normal range, usually due to slow leaks, punctures causing underinflation, or overinflation. Methods to reset the tire pressure warning include: 1. Visit a 4S shop and have technicians use professional diagnostic tools to reset it; 2. Press and hold the tire pressure monitoring button to reset. Tire pressure refers to the air pressure inside the tires, which is essentially the 'blood pressure' of a car. The level of tire pressure plays a crucial role in the vehicle's performance and power. Nowadays, many tires are filled with gases other than air, and these tires have stricter pressure requirements. For tires filled with air, pressure adjustments may be needed with seasonal changes, and tire pressure is closely linked to vehicle performance, such as comfort and load capacity, as well as affecting tire lifespan.

Why does a sedan's brakes make noise?

Car brakes making abnormal noises can be attributed to the following reasons: 1. The car is new or has just had new brake pads installed, which is a normal phenomenon. 2. Rust on brake discs or pads: After parking for a long time, especially in humid weather or after rain, some rust or dirt may appear on the brake discs or pads. In this case, you can apply butter or special lubricating oil at the connection between the brake pads and the brake calipers. 3. Excessive wear of brake discs and pads: Both brake discs and pads are high-wear items. Every time you brake, these two components rub against each other, leading to natural wear over time. When the wear becomes excessive, abnormal noises may occur, so regular inspection and replacement are necessary.

How soon can I reschedule after failing Subject 2?

After failing Subject 2, you must wait at least 10 days before rescheduling. Below are the specific details regarding Subject 2 rescheduling: 1. According to Article 44 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," each subject can be taken once, with one retake allowed if failed. If you do not take the retake or fail it again, the current examination ends. Applicants must reschedule the exam, but Subject 2 and Subject 3 exams must be scheduled at least 10 days later. If you fail the Subject 3 safety and civilized driving knowledge test, the previously passed road driving skills test scores remain valid. 2. Within the validity period of the driving study certificate, the number of rescheduling attempts for Subject 2 and Subject 3 road driving skills tests must not exceed five. If you fail the fifth rescheduled exam, all previously passed subjects will be invalidated.

How to Remove Dirt from White Car Paint?

White car paint dirt removal methods are introduced as follows: 1. Asphalt: If a large amount of asphalt is adhered to the car body, it can be cleaned with a tar remover. Remember to wear gloves when using the tar remover. 2. Bird droppings and other impurities: For vehicles frequently parked under trees, they are bound to be attacked by bird droppings or tree sap and other impurities. If the stains on the car body are substances like bird droppings, they can be soaked with car shampoo or glass cleaner, and after softening, they can be easily removed. 3. Iron powder: If the stains on the car body are dense iron powder, the above cleaners cannot remove them. Only by using special clay bars or stain removal cloths, and slowly grinding them after washing the car body, can they be removed. (Excessive use of clay bars/cloths may cause the paint surface to lose luster and become dull, so after use, it is advisable to apply a layer of wax to the car body.)

How to Determine if the Drive Shaft Bearing is Faulty?

Here are the methods to determine if the drive shaft is damaged: 1. Damage, wear, deformation, or loss of dynamic balance in the drive shaft can cause abnormal noises and vibrations while driving. 2. During driving, noises may occur when starting or accelerating sharply, accompanied by a feeling of loose components. Below is an analysis of the causes of drive shaft failure: 1. Loose connections (or connecting bolts) at the flange joints of the drive shaft. 2. Loose fixing bolts of the intermediate support bracket of the drive shaft, resulting in excessive clearance between the intermediate support and the intermediate drive shaft journal. 3. Disintegration of the intermediate support bearing of the drive shaft, damage to the bearing raceway, poor bearing lubrication, or excessive wear leading to looseness. 4. Misalignment of the intermediate support bracket installation position, improper adjustment of bearing preload, damage to the rubber spacer ring, or incorrect tightening torque of the intermediate support bracket fixing bolts (either too tight or too loose) causing bracket misalignment, leading to abnormal noises.
