The differences between diesel engine oil and gasoline engine oil are: 1. Different API ratings: Diesel engine oil ratings start with 'C'; Gasoline engine oil ratings start with 'S'. 2. Different combustion flame temperatures: Diesel engine oil combustion flame temperature is 1800 degrees Celsius; Gasoline engine oil combustion flame temperature is 600 degrees Celsius. The functions of engine oil are: 1. To alleviate friction and high temperatures; 2. To reduce gas leakage and prevent external pollutants; 3. To prevent contact between water, air, acidic harmful gases and parts; 4. To buffer the pressure rise at the engine cylinder port; 5. To flush away dirt generated on the working surfaces of parts.

What is the difference between 225 and 235 tires?

The main differences between 225 and 235 tires are: 1. 225 tires have poorer vibration absorption, resulting in a harder road feel. They place certain demands on the suspension system, otherwise the car may experience more bumpiness. 2. 235 tires provide better road grip, offering drivers a stronger sense of driving comfort. Methods to identify tire quality: 1. Observe the tread pattern color and gloss: If the tire is a poor-quality retread, its processing may be non-standard, resulting in shallower tread grooves. 2. Color: Inferior tires often appear excessively bright in color, while regular tires tend to have relatively darker tones. 3. The joint between tread and sidewall: Inferior tires may have missing markings on the sidewall. Wear marks in the anti-slip grooves of the tread may still be visible.

What kind of engine oil should be used for Honda Vezel?

The original engine oil is the one used for Honda Vezel, with the model number 5W-30. In terms of applicability, the original oil is more suitable for the engine. However, depending on different needs, engine oil can also have other functions, such as noise reduction, fuel efficiency, and power performance. Therefore, you can also choose engine oils from brands like Mobil, Shell, and Castrol. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand low temperatures of -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the number, the better it maintains viscosity at high temperatures, which can also be understood as better lubrication performance under high temperatures. The method for changing the engine oil for Honda Vezel is as follows: Wait for the engine temperature to drop, allowing the oil to flow back to the oil pan; use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to flow out; use a special wrench to remove the oil filter; apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; add the new oil through the oil filler cap on the engine valve cover, usually filling up to three-quarters of a bottle; start the engine and let it run for 5 minutes, then check for oil leaks around the oil drain plug and oil filter, and repair if necessary; after stopping the engine, pull out the oil dipstick to check if the engine oil is within the standard range.
