Several factors affect how much tension occurs when a given amount of tightening torque is applied. The first factor is the bolt's diameter. It takes more force to tighten a 3/4-10 bolt than to tighten a 318-16 bolt because it is larger in diameter This is a very important topic for spacecraft designers. It is amazingly complicated.

Most applications that use bolts require between 10 and 150 foot-pounds of torque. Use at least a 5/8-11 grade 8 bolt for applications that require higher levels of torque.

Even if there is a torque spec for an oil pan drain plug, that torque spec will be most likely for dry threads, and that will not be the case here. Oiled threads will decrease the friction in threads to the point where the preload on the bolt will be practically twice as high as if the threads were dry
