What Type of Engine Oil is Recommended for the Eighth-Generation Accord?
3 Answers
The recommended engine oil type for the eighth-generation Accord is SL 5W/30, supplied by Tianjin Nisseki. If you wish to change the oil during later maintenance, you may opt for Mobil 1 SM 0W/40 synthetic oil. The manufacturer recommends 5W30 or 5W40, and any oil matching these specifications can be used. The viscosity of engine oil varies with temperature, so it is crucial to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the vehicle. The second number represents the kinematic viscosity of the oil at 100°C. A higher value indicates better viscosity retention at high temperatures, which can also be interpreted as superior lubrication performance under high-temperature conditions. The method for changing the engine oil in the eighth-generation Accord is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan. Use a wrench to loosen the drain plug and place an oil pan underneath 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 drain out. Use a specialized wrench to remove the oil filter. Apply some oil to the gasket 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. Typically, fill up to three-quarters of a standard oil container. Start the engine and let it run for 5 minutes, checking for any leaks around the drain plug and oil filter. If leaks are found, perform necessary repairs. After stopping the engine, pull out the dipstick to check if the oil level is within the standard range.
I've driven my 8th generation Accord for many years. Based on personal experience and manual recommendations, the best engine oil grades are 0W-20 or 5W-20 full synthetic or semi-synthetic oils. Living in the north, 0W-20 performs better during cold winter starts, protecting the engine from wear. In summer, 5W-20 works just fine as it won't become too thin in high temperatures. I usually change the oil myself every 8,000 kilometers on average - it's cost-effective and gives me peace of mind. Always choose modern API-certified oils and never compromise quality for cheaper alternatives. Additionally, check oil levels before long trips to avoid engine damage from oil starvation. Overall, these oil grades are very Accord-engine friendly, extending engine life while improving fuel efficiency.
As someone who frequently works with these cars, I recommend using 0W-20 or 5W-20 low-viscosity engine oil for the eighth-generation Accord. It suits Honda's engine design and reduces internal friction losses. During maintenance, I've seen too many users encounter problems caused by using high-viscosity oil. Pay special attention to whether the oil carries ACEA standard certification to prevent oxidation and deterioration. Change the oil on time, approximately every 5,000 kilometers, and don't delay. Different driving environments affect the choice; if you frequently encounter traffic jams or drive long distances on highways, fully synthetic oil is more durable. In short, choosing the right oil ensures a smooth and quiet engine with fewer minor issues.
