What Type of Oil Should Be Used for the 2019 Sylphy?
3 Answers
The official manual for the 2019 Sylphy recommends engine oil with a specification of 5W-30. Any oil that meets this specification can be used. If you want to change the oil during later maintenance, you can choose brands such as Shell, Mobil, Castrol, or Total. The viscosity of engine oil changes with temperature, so special attention should be paid 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 car. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as providing better lubrication performance under high-temperature conditions. The method for changing the oil in the 2019 Sylphy is as follows: Wait for the engine temperature to drop and allow the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine for 30 seconds to allow the oil in the main oil passages to drain out; Use a specialized wrench to remove the oil filter; apply oil to the 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. Generally, fill up to three-quarters of a standard oil container; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs; After stopping the engine, pull out the oil dipstick to check if the engine oil level is within the standard range.
I've been driving a 2019 Nissan Sylphy for three years, always using fully synthetic engine oil, preferably with a viscosity of 5W-30 or 0W-20, as recommended in the user manual for optimal engine protection. For mostly city driving, 0W-20 offers better fuel efficiency, while 5W-30 is more versatile for long-distance trips or variable weather conditions. I change the oil every 8,000 kilometers, which is both cost-effective and hassle-free. For brands, I stick to reputable ones like Shell or Mobil 1 for reliable quality. Regular maintenance shouldn't focus solely on oil—always replace the oil filter to ensure cleanliness, which reduces engine noise and maintains steady performance. The Sylphy is an economical and practical car, and using high-quality oil extends its lifespan, avoiding major repairs. I recommend getting oil changes at authorized service centers and avoiding cheap, off-brand products. Regularly check oil levels, especially in winter, to ensure quick starts and prevent engine damage.
I've been using my 2019 Sylphy for nearly two years, and choosing full synthetic oil is crucial. The manual says both 5W-30 and 0W-20 are acceptable, but I prefer 0W-20 as it suits Nissan engines better and offers lower fuel consumption. Changing oil myself is quite simple: prepare 4 liters of oil and a matching filter, find an open space, first loosen the drain plug to remove old oil, then install the new filter and add fresh oil. Full synthetic oil has a longer change interval, needing replacement only around 8,000 kilometers, which saves time. I've used Castrol brand and found it excellent, with smooth engine operation. It's also important not to change oil viscosity arbitrarily, as it might affect acceleration or cause oil burning. By the way, regularly cleaning the air filter can enhance performance when paired with good oil, making driving more enjoyable.
