2 Answers
Great Wall C30 oil change method: 1. Run the engine until it reaches operating temperature. Then use a jack to lift the vehicle, engage the handbrake and secure the front wheels with wooden wedges. 2. Place an old oil container under the oil pan, locate the oil pan drain plug, slowly loosen the drain plug, being careful not to come into contact with the hot oil. 3. Move the oil container under the oil filter, use an oil filter wrench to loosen the filter, then unscrew it by hand. If the filter is still hot, remember to wear gloves. 4. Refer to the user manual to select the appropriate oil filter. 5. Apply new oil to the gasket of the new filter. If the filter is installed vertically, you can pour some new oil into the filter to reduce dry friction during the next engine start. 6. Pour the new oil into the oil pan, referring to the instructions in the user manual. 7. Turn off the engine and recheck the oil level. Dispose of the used oil and filter according to local regulations.
I've been driving a Great Wall C30 for five or six years and change the engine oil myself every time—it saves money and gives me peace of mind. Prepare the tools: a set of wrenches, a new oil filter, engine oil with the right viscosity (about 3.5 liters of 0W-30 or 5W-30 for the Great Wall C30), an oil pan, and a funnel. Park the car on level ground and engage the handbrake. Start the engine for a few minutes to warm up the oil for easier flow, then turn it off and let it cool for half an hour to avoid burns. Crawl under the car and locate the oil drain plug on the engine oil pan. Slowly loosen it with a wrench, letting the old oil drain into the pan. Once done, carefully tighten the plug back without over-tightening to avoid damaging the threads. Next, replace the oil filter, usually near the drain plug—unscrew the old filter, wipe the base clean, and install the new one, applying a bit of fresh oil to the seal. Before adding new oil, ensure the drain plug is tight. Use a measuring cup or funnel to slowly pour in the new oil, avoiding spills. Start the engine and let it idle for a minute to check for warning lights on the dashboard. After turning it off, check the dipstick—the oil level should be between the marks. It’s recommended to change the oil every 5,000 kilometers or six months.
