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