Is the Refine M3 really fuel-consuming?

What should the battery starting voltage reach?

Battery starting voltage should reach 9-12V. Here is an extended introduction: 1. Maintain cleanliness: Keep the battery clean and dry, and ensure the vent holes are unobstructed. When oxides appear on the plates or terminals, wipe them clean and apply a small amount of grease to prevent corrosion. 2. Do not use the starter continuously: Each use should not exceed 5 seconds, and after two starts, rest for 10-15 seconds before using again. In severe winter, the battery discharge level should not exceed 25%, and in summer, it should not exceed 50%. 3. Regular charging: A battery filled with electrolyte should not be left in a state of insufficient charge for a long time; it should be charged regularly, otherwise it may lead to scrapping.

What are the tips for removing asphalt from a car?

To remove asphalt from a car, the main methods are as follows: 1. Use asphalt cleaner to remove asphalt: Special asphalt cleaner can quickly penetrate and dissolve asphalt, effectively cleaning tar and asphalt stains on the car body and wheel hubs. It provides excellent stain removal, cleaning, and polishing effects, but the car body should be rinsed with clean water immediately after cleaning. 2. Use essential balm or diesel to remove asphalt: Essential balm can dissolve asphalt. Apply a few drops of essential balm on the asphalt surface of the car body, wait for 5 minutes, and then wipe it clean with a wet towel; diesel can also dilute and dissolve asphalt. Composition of asphalt: The main component of asphalt is hydrocarbons, which are insoluble in water but soluble in carbon disulfide. If asphalt sticks to the car, simple water washing won't remove it, but avoid using tools to scrape it off as it may scratch the car paint.

What are the pros and cons of a straight-through header?

The pros and cons of a straight-through header are as follows: 1. The advantage is smoother exhaust flow and strong high-RPM horsepower. 2. The disadvantages include loss of low-end torque in D gear, foul odors, and lack of environmental friendliness. Below is some relevant information about headers: 1. The header is the part directly connected to the engine's exhaust. Modifications in this area usually involve upgrading the entire exhaust system with larger diameters. Converting to a straight-through header, paired with a high-flow intake, makes exhaust emissions and acceleration smoother while increasing power. 2. Of course, if not done properly, it may not only fail to provide benefits but also negatively affect the car's original performance. Straight exhaust emissions may not meet standards. Modified straight exhaust pipes typically result in weaker low-RPM performance, increased noise, and excessively loud volume. Untreated exhaust emissions exceeding standards can cause severe pollution, with foul odors entering the cabin and increased fuel consumption.

What is the difference between tire aspect ratios of 40 and 45?

The differences between tire aspect ratios of 40 and 45 are as follows: 1. Different aspect ratios: High aspect ratio tires have longer sidewalls and stronger cushioning ability, providing relatively higher comfort but poorer road feel and weaker lateral resistance during turns. Low aspect ratio tires with large inner diameters have shorter sidewalls and wider treads, resulting in larger contact areas and greater pressure-bearing capacity. They offer very sensitive road response, strong lateral resistance during turns, and excellent vehicle handling. 2. Different tire thickness: Tires with a 40 aspect ratio should be used on roads with good conditions to avoid bulges that may lead to blowouts. For 45 aspect ratio thin tires, it is advisable to drive on well-maintained roads as low aspect ratio thin tires will not affect tire performance under such conditions.

Can vehicle electrical appliances be used when the ignition switch is in the ON position?

Vehicle electrical appliances can be used when the ignition switch is in the ON position. Introduction to car ignition switch positions: 1. LOCK: Locks the car. Generally, placing the key in this position locks the steering wheel, preventing significant movement. 2. ACC: Powers the entire vehicle, allowing normal use of the radio, lights, etc., but not the air conditioning. 3. ON: All basic equipment except the starter is on. This position unlocks the steering wheel and allows the use of air conditioning, but without cooling effect as the compressor is not activated—only the blower operates, producing natural airflow. During normal driving, the key remains in the ON position, with all vehicle circuits operational. 4. START: Starts the car, ignites the engine, consumes fuel, and activates the vehicle. The air conditioning begins cooling. The START position is for engine ignition; after starting, it automatically returns to the normal ON position.
