The torque specification for the Lavida 1.6 naturally aspirated oil drain plug is 30Nm. Function of the oil drain plug: During an engine oil change, it allows the dirty oil inside the engine to be drained. After draining the old oil, tightening the drain plug enables new oil replacement while providing sealing. Replacement interval for oil drain plugs: To ensure driving safety and enhance maintenance experience, it's recommended to follow the vehicle's maintenance schedule. The drain plug should be replaced periodically according to the model's service intervals. During maintenance, replacement is required if oil seepage occurs or after the plug has been removed twice for service procedures.

The standard torque for the drain plug of the Lavida 1.6 naturally aspirated engine is approximately 25-30 Nm, but you should always refer to the maintenance manual for specifics. Last time I changed the oil myself, I set the torque wrench to 28 Nm and stopped when I heard the 'click' sound. Always remember to replace the gasket! A friend of mine once skipped replacing it, and halfway through driving, the oil leaked so much it turned the road into a 'rainbow,' and even scratched the oil pan. The mechanic said the threads on these aluminum oil pans are quite delicate—over-tightening can strip them, requiring a replacement of the entire oil pan, which costs hundreds more than the original gasket (about 100 times the price).

I've been repairing Volkswagen cars for ten years, and the torque for the oil drain plug on the Lavida 1.6 is best controlled at 28±2 Nm. Some people prefer to rely on feel and 'tighten it another half turn,' which often results in the oil pan threads getting stripped. When using a socket wrench, make sure the angle is perpendicular; tilting it can easily round off the screw head. Last time, I saw an owner using a regular wrench to tighten it with all their might, and in the end, we had to heat the screw red-hot with a welding torch to remove it. The labor cost alone was enough to buy three bottles of full synthetic oil.

Car enthusiasts group test data: For the 15th-gen Lavida 1.6, a drain plug torque of 25 Nm is sufficient, while older models may require up to 30 Nm. Park the car on level ground and wait half an hour before starting to allow the oil to drain back into the oil pan. Prepare a basin to catch the oil when loosening the plug—my first attempt left the floor looking like a crime scene. Choose copper washers over aluminum ones for better sealing and pressure resistance. You can rent a torque wrench for just 80 yuan on Xianyu, which is much more cost-effective than repairing stripped threads.
