What type of engine oil is suitable for the 1.5T Civic?

[LeElle]

The 1.5T Civic can use 0W20 or 5W30 fully synthetic engine oil. For city commuting, 0W20 oil is suitable; for aggressive driving, 5W30 oil is recommended. Engine oil, or motor lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. The 1.5T Civic is a compact car launched by Dongfeng Honda, with the following specifications: Civic 2019 220TURBO Manual Jingkong Edition (China VI): Body length 4658mm, width 1800mm, height 1416mm, wheelbase 2700mm, equipped with a 1.5L turbocharged engine, maximum power 130kw, paired with a 6-speed manual transmission. Civic 2019 180TURBO CVT Shangyue Edition (China VI): Body length 4658mm, width 1800mm, height 1416mm, wheelbase 2700mm, equipped with a 1.0L turbocharged engine, maximum power 92kw, paired with a continuously variable transmission (CVT). Civic 2021 Edition: Body length 4517mm, width 1799mm, height 1434mm, wheelbase 2700mm, equipped with a 1.5L turbocharged engine, maximum power 130kw, paired with a continuously variable transmission (CVT). Civic 2022 240TURBO CVT Jindong Edition: Body length 4674mm, width 1802mm, height 1415mm, wheelbase 2735mm, equipped with a 1.5L turbocharged engine, maximum power 134kw, paired with a continuously variable transmission (CVT). Civic 2022 180TURBO CVT Shangdong Edition: Body length 4674mm, width 1802mm, height 1415mm, wheelbase 2735mm, equipped with a 1.5L turbocharged engine, maximum power 95kw, paired with a continuously variable transmission (CVT). Engine oil types are categorized as follows: Semi-synthetic oil is a type of engine oil made from semi-synthetic base oil, which is derived from Group III base oils. It is a refined product of mineral oil through hydro-cracking technology, blended in a 4:6 ratio with mineral and fully synthetic oils. Semi-synthetic oil is very close in purity to fully synthetic oil but is slightly more expensive than mineral oil, making it an ideal transitional product between mineral and synthetic oils. Fully synthetic oil offers a wider temperature range and longer service life. For the same film requirements, synthetic oil can achieve the desired performance with lower viscosity compared to semi-synthetic oil, which requires higher viscosity. Conventional mineral oil consists of base oil and additives. The base oil is the main component, determining the basic properties of the lubricant, while additives compensate for and improve the base oil's performance, adding new characteristics and making it an essential part of the lubricant. Engine oil viscosity changes with temperature, so it's crucial to pay attention to performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity (5W can withstand -30°C), with smaller numbers indicating better low-temperature fluidity and easier cold starts. The second number represents the oil's kinematic viscosity at 100°C, with higher numbers indicating better high-temperature viscosity retention and lubrication performance. For viscosity selection, 5W oil is generally sufficient for winter in many regions, while 0W is recommended for northern areas (e.g., Harbin) due to its superior low-temperature fluidity to meet local conditions. High-temperature viscosity typically uses 20, but for frequent driving in congested areas, older vehicles, or heavy-duty long-distance transport, higher viscosity oils like 0W30 can be considered. When selecting engine oil, note the following: Choose oil based on the engine's requirements—avoid using overly advanced oil for lower-demand engines or inferior oil for high-demand engines. Multi-grade oils are preferred for their efficiency, longevity, and engine protection. Due to their properties, multi-grade oils may darken prematurely or show lower oil pressure than conventional oils, which is normal.
