What type of oil should be used for the eighth-generation Civic?

The 1.8L eighth-generation Civic should use semi-synthetic or higher-grade oil with the manufacturer-recommended viscosity of 5W-30. For the 1.5T engine, the manufacturer requires semi-synthetic or higher-grade oil with 0W-20/5W-30 viscosity. Method for changing the oil: Loosen the nut at the bottom of the transmission oil pan to allow the old transmission oil to drain naturally by gravity. Connect the transmission to a circulation machine via pipeline interfaces, and the new transmission oil will push out the old oil under pressure. Methods to determine if the oil needs to be changed: Pull out the oil dipstick and smell it closely. If there is a strong sour or foul odor, it indicates the oil has deteriorated and should be changed. Rub the extracted old oil repeatedly between your thumb and forefinger. If you feel impurities, poor viscosity, or even a gritty sensation, it should be changed. Hold the oil dipstick at a 45-degree angle under light and observe the oil droplets. If the droplets are clear without visible wear particles, the oil is in good condition. If there are many wear particles, the oil should be changed.
I used to drive an eighth-generation Civic, and maintenance really requires attention. The factory manual specifies using 0W-20 or 5W-20 engine oil. I've tried several types and found full synthetic to be the smoothest, especially during cold winter starts—it fires up quickly. Always look for the API certification mark, like SN or SP grade, which is sufficient. 5W-20 is easier to find at regular repair shops and more affordable. Never use high-viscosity oil casually, as it can actually increase engine noise and fuel consumption. I change the oil every 7,000–8,000 kilometers, and even after ten years, the engine remains as quiet as new. During routine maintenance, always check the dipstick—if the oil level is too low, be alert for potential leaks.
I've been pondering the oil selection for the 8th-gen Civic for quite some time, and the key is sticking to 20 viscosity. Most owner's manuals recommend either 0W-20 or 5W-20 specifications. The former offers better low-temperature fluidity, making it more worry-free for northern drivers during winter. Look for the Honda certification mark or ILSAC energy-conserving certification on oil containers for reliability. I typically use full synthetic oils from Mobil or Idemitsu, with an oil change interval of 7,000-8,000 kilometers being perfectly adequate. Never opt for cheap, small-brand oils to save money—last year, I encountered a case where incorrect oil usage led to VTC actuator noise. During maintenance, ask the mechanic to check the valve cover gasket as well, since this car is prone to oil seepage as it ages. Pay attention to the engine sound at traffic lights; if you hear metallic knocking noises, check the oil immediately.
