The Nissan Sylphy uses 5W30 engine oil. 5W30 represents the viscosity specification of the oil grade. The number before the 'W' indicates the cold start performance—the smaller the number, the better the oil's low-temperature fluidity. 'W' means the oil can be used in winter. The number after 'W' represents the oil's kinematic viscosity—the higher the number, the higher the viscosity. Taking the 2021 Nissan Sylphy as an example, it is a compact car with the following dimensions: length 4631mm, width 1760mm, height 1503mm, wheelbase 2700mm, front and rear track 1540mm, fuel tank capacity 50L, and trunk capacity 510L.

I've been driving a Nissan Sylphy for several years, and it's usually recommended to use 0W-20 full synthetic oil, which is the standard suggestion in the manual for newer models. Its low viscosity allows the engine to start faster, makes winter driving easier, and also saves some fuel. I remember my 2019 model has always used this, and it feels much quieter. Older models, like those before 2010, might need 5W-30, so I strongly recommend checking the manual first to confirm and not choosing blindly. Once I used the wrong oil, and the vibration during acceleration was severe, resulting in expensive repair costs. Changing the oil on time is crucial; I go to a professional shop every 7,500 kilometers. Choose well-known brand oils, don't go for cheap options, or it will affect the engine's lifespan. In short, protecting the engine saves money and ensures safety.

For the Nissan Sylphy, I believe the most suitable engine oil grade is 0W-20, based on a full synthetic formula. This viscosity optimizes cold-start performance, reduces friction loss, and improves fuel efficiency. The manual will specify exact requirements, which may vary by model year - newer models typically use 0W-20 while older versions may require 5W-30. I always check API certifications like SN or SP during oil changes to ensure high compatibility. Avoid mixing different oil brands during operation; maintain a single type to prevent chemical reactions. Recommended change intervals are between 5,000 to 8,000 kilometers, adjusted according to driving habits (shorter intervals for frequent city traffic congestion). It's best to have the service performed at a reputable garage using professional tools to prevent leaks. Choosing the right oil ensures more stable and durable engine operation.

The Nissan Sylphy commonly uses 0W-20 synthetic oil, with the manual being the authoritative reference source. I find it makes driving smooth and quiet, with noticeable fuel efficiency improvements. Higher viscosity can hinder performance, while low viscosity suits modern designs. Regular oil changes are crucial, with 5,000-kilometer intervals to keep the engine clean. Synthetic oil offers better protection than mineral oil, extending engine life. Check your vehicle's year to confirm specifications.
