What kind of engine oil should be used for CRV maintenance?
3 Answers
CRV maintenance uses fully synthetic engine oil because it has excellent lubrication effects and can extend the engine's service life. Below is an introduction to engine oil: 1. Engine oil: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a car. 2. Key features: The engine is the heart of a car, containing many metal surfaces that move against each other at high speeds in harsh environments, with operating temperatures reaching 400°C to 600°C. Advanced technology can convert natural gas into crystal-clean fully synthetic base oil, which is then enhanced with proprietary power-cleaning technology to create lubricants with superior cleaning and protective performance.
My CR-V has been running for seven years, always using 0W-20 full synthetic oil. The Honda OEM green barrel type is just fine, offering excellent cold start protection in winter and making the throttle feel light and responsive. Remember to change it every 7,000 to 8,000 kilometers—don't wait until the oil turns as black as ink before servicing. When changing the oil, replace the oil filter as well; a roadside repair shop can handle it for around a hundred bucks. If you frequently drive on highways or enjoy heavy throttle inputs, consider upgrading to a full synthetic like Mobil 1 Gold—it's pricier but significantly reduces engine noise. Never skimp and use mineral oil; modern engines are too precise, and poor-quality oil can easily lead to carbon buildup.
For the new CR-V, it's recommended to use 0W-20 oil as specified in the manual. This viscosity is most suitable for Japanese cars. Full synthetic oil offers better fluidity and can reduce fuel consumption by about 0.5 liters. I service my car every six months, and the dealership's purple bottle full synthetic oil package costs 380 RMB including labor, which seems more reliable than buying unknown brands online. For areas with temperatures as low as -20°C in the north, 5W-30 is also acceptable, but never mix oils with different specifications. A little tip: after changing the oil, check the dipstick. Overfilling can make the engine feel sluggish, while underfilling can wear out the piston rings. If you're doing it yourself, buy a reputable brand funnel to avoid spilling oil on the engine.
