The oil specification for the Sylphy is 5W40 fully synthetic oil. Fully synthetic oil has stable physicochemical properties, offering superior lubrication, high-temperature resistance, and oxidation resistance. Taking the 2021 Sylphy as an example, it is a compact car with body dimensions of: length 4631mm, width 1760mm, height 1503mm, wheelbase 2700mm, fuel tank capacity 50L, and curb weight 1188kg. The 2021 Sylphy features a MacPherson strut front suspension and a torsion beam rear suspension. It is equipped with a 1.6L naturally aspirated engine, delivering a maximum horsepower of 122PS, maximum torque of 155Nm, and maximum power of 90kW, paired with a 5-speed manual transmission.

I've been driving a Sylphy for five years, and experience tells me the engine oil grade depends on the specific model and year. Generally, 5W-30 full synthetic oil is recommended—smooth winter starts and summer engine protection. Newer Sylphy models might be better suited with 0W-20 in colder regions. The manual clearly states not to use the wrong oil grade, as it can wear engine components and reduce lifespan. I change my oil every 5,000 km to ensure cleanliness. The Sylphy engine isn't overly demanding on oil, but using the wrong type can lead to increased noise or higher fuel consumption. Always get maintenance done at a 4S shop or reputable garage—it saves money and gives peace of mind. If you don't understand the terms in the manual, just ask the after-sales service instead of experimenting blindly.

As an average car owner, I prioritize straightforward maintenance for the Sylphy. The commonly used 5W-30 engine oil has moderate viscosity suitable for most driving conditions. I always check the manual during oil changes – new models may specify 0W-20, so don't mix them up. Engine oil doesn't just lubricate; it also cools and prevents rust. Using the correct grade maintains normal fuel consumption and reduces noise. Regularly check oil levels – don't wait for leaks to act. When purchasing oil yourself, choose reliable full-synthetic brands like Shell or Mobil. Remember to change every six months or 5,000 km to keep your engine running healthily.

A bit technical: Oil grades like 5W-30 represent viscosity and flowability; a lower number before W means better cold starts, while the number after indicates high-temperature protection. The Sylphy commonly uses 5W-30 or 0W-20 synthetic oil as it matches Nissan's engine design standards—I've tested the former and found the engine runs smoothly. Choose SN or SP grade for better anti-pollution performance, avoid outdated models to prevent issues. Simply check the manual against the year—safety first.
