What Type of Engine Oil Does the Haoying Use?
2 Answers
The original factory oil is the engine oil used for the Haoying, with the oil model being 0W-20. In terms of applicability, the original factory oil is more suitable for the engine. However, depending on different needs, engine oil can also have other benefits, such as noise reduction, fuel efficiency, and enhanced 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 is needed to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the number, the better it can maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the Haoying's engine oil is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain 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 engine oil through the oil filler cap on the engine valve cover, usually filling up to three-quarters of the oil container; start the engine and let it run for 5 minutes, checking for any oil leaks around the oil drain plug and oil filter, and repair if necessary; after stopping the engine, pull out the dipstick to check if the engine oil level is within the standard range.
I've been driving the Breeze for two years and always use 0W-20 full synthetic oil for oil changes, which is a perfect match for Honda's engine. The low viscosity means 0W allows faster cold starts, while 20 protects the engine from wear at high temperatures, improving fuel efficiency slightly. The API SP standard gives extra peace of mind by preventing carbon buildup issues. Once I tried a cheaper 10W-30 oil, and the engine immediately started humming louder while fuel consumption increased. Remember to check your manual based on the car's year – generally recommended to change oil every 5,000 to 10,000 kilometers, don't delay too long. In colder climates, thinner oil is even more essential to avoid engine seizure. Use premium brands like Shell or Mobil, don't cut corners with inferior products to save money, otherwise long-term wear will lead to higher repair costs.
