Engine oil drain plug torque spec
I am changing my mom's oil on 2006 c230 sport and I need the oil drain plug torque spec. I have seen 30nm (22ft/lbs) all the way down to 18 ft/lbs.
Please advise.
I am sure this is somewhere here but as I have spent hours searching to no avail I thought I post this

Either 18ft or 22ft/lbs is fine. 
However, 30NM is the spec:

The top level link for the manuals follows. Yes, they are a PITA to navigate. But, they are free and quick to access online.
Btw, a C230 2007 is the same as a C230 2006.

Since you're clearly new at doing automotive stuff, and you're smart enough to read and *try to understand the factory procedures and specs*, more importantly, what are you using for a low-range torque wrench?
It would have to be either a 3.8" or 1/4" torque wrench. In general, both of those are rare with many DIY (Do It Your-selfers), since they often (imho, foolishly) use "their hands" to estimate force on many bolts.
Fwiw, for an oil bolt, even a little experienced hand can get the right torque. However, until you get the feeling for force for many bolts, it is best to use a torque wrench to get the "right feel".
As an engineer, tools are part of my toys! I have a good idea of accuracy and price-point that makes sense for my needs and desires. So, I have a few low-range torque wrenches. And, I have a number of torque wrenches. :-)
Good Luck!

Thanks so much RedGray 
Yes I am a noob. Just finished my first oil change on my M3 and decided to do my mother's car as well. I have a 1/4", 3/8" and 1/2" drive torque wrenches available to me. I agree I do not have the feel yet and so I will depend on tools so I don't mess anything up.
