After all these years in auto repair, I've encountered countless issues with oil drain plug torque. The manuals do specify torque values, which vary by vehicle model. For example, Japanese cars typically require 25-30 Nm, while German cars generally need 20-25 Nm. There's profound reasoning behind these numbers: insufficient torque causes oil leaks, while over-tightening may damage the oil pan threads. Just last week, a customer overtightened the plug himself, resulting in stripped threads that required a full oil pan replacement - quite an unnecessary expense. I always advise apprentices to use a torque wrench rather than relying on feel. Actually, besides the drain plug, it's best to replace the crush washer each time too for optimal sealing.

Last time before changing the engine oil for my beloved car, I carefully went through the owner's manual and found the standard torque values in the engine maintenance section. Many beginners don't realize that torque requirements vary significantly for different bolt locations – for instance, the tightening force for the drain plug and oil filter bolt are completely different. After following the manual's specifications this time, I specifically monitored for several days and found the chassis remained clean without any oil stains. I recommend downloading the electronic version of the manual to keep on your phone for reference – many brand official apps now allow direct access to maintenance parameters. Also remember to use new gaskets, as reusing old ones can easily lead to oil leaks.
