For the Nissan Sylphy Classic with a 1.6L engine, approximately 3L of engine oil is generally required, while the 1.8L engine model typically needs around 4L. The exact amount of oil to be added should be between the upper and lower marks on the dipstick, with the dipstick serving as the standard for the optimal oil level. Below are the steps for changing the engine oil: 1. Remove the oil filler cap. 2. Place an oil drain pan under the drain plug. 3. Use a wrench to loosen the drain plug and drain the oil. 4. After the oil has completely drained, reinstall the drain plug and tighten it to the specified torque (55±5N.m). 5. Slowly add engine oil through the filler hole until it reaches the upper mark on the dipstick. 6. Use an absorbent cloth to wipe away any spilled oil and replace the oil filler cap. 7. Start the engine and let it idle for 1 minute, then turn it off and wait for 5 minutes before checking the dipstick again.

After driving the Nissan Sylphy Classic for so many years, I've found that the engine oil capacity is around 4.5 liters, depending on the engine year and model. For my 1.6L engine, this is the amount I add during each oil change. If you add too little, insufficient lubrication can cause the engine to overheat and accelerate part wear; adding too much may leak into the combustion chamber, increasing carbon buildup and fuel consumption. I recommend using 5W-30 full synthetic oil for the best protection. I change the oil every 5,000 kilometers, warming up the car first to drain the old oil before adding new oil. After ensuring the correct amount, I use the dipstick to check that the oil level is in the middle, neither below MIN nor exceeding MAX. Regular maintenance like this can extend engine life, save on repair costs, and keep the car running smoothly and fuel-efficiently.

When it comes to the oil capacity of the Sylphy Classic, generally 4 to 4.5 liters is sufficient. Avoid adding too much or too little. Overfilling can cause the oil to foam, affecting lubrication and leading to oil pressure issues; insufficient oil may damage internal components like the crankshaft, requiring premature overhaul. It's recommended to check the oil level when the engine is cold to ensure it's at an appropriate level. I use 5W-30 synthetic oil, which has suitable viscosity, high-temperature resistance, and anti-wear properties. The oil change interval should be around 7,500 kilometers, and the filter should be replaced at the same time. Ensure the old oil is completely drained to avoid residue affecting performance. Regular maintenance like this saves a lot of trouble and makes driving safer and more reliable.

When I first learned DIY car maintenance, I found that adding 4.5 liters of oil is suitable for the Nissan Sylphy Classic. Changing it yourself is quite simple: first, buy a 4-liter bottle and top it up with a smaller bottle to reach the required amount. Use a funnel to pour in the new oil, then start the engine and let it run for a few minutes before turning it off. Wait a while, then check the oil dipstick to ensure the level is between the MIN and MAX marks. Avoid overfilling or underfilling to prevent performance issues. If it's your first time and you're not comfortable, it's recommended to follow the manual's instructions or learn from a professional shop for more accurate and faster results to protect your car.
