2011 bmw m3 oil change question
I was searching the forum for a DIY on changing oil. I found:
http://www.m3post.com/forums/showthread.php?t=185785 My question is, are they any differences between the model years? I have a 2011, does anyone know the drain bolt size; 6mm or 8mm? Is torque values 18lbs? Thanks guys, going to do my oil change tomorrow and want to make sure I follow the DIY for the torque values as long as it's consistent with all model years.

No difference between years. I believe drain bolt is 6mm hex. 25-nm sounds about right. I believe the torque value for the filter is on the cap.

I just read the DIY again and realized the 25nm is for oil filter housing. The drain plugs are only 10nm...is this correct?

Thanks guys, I just read a thread where it stated the oil filter housing changed for 2011+ to 40nm and the plugs should be tightened to 25nm.
Confusing

Just hand tighten them and you'll be ok, just don't over-tighten and strip it. That's what I did with my 2008 M3 and it was fine when I traded it in at 89k miles, no leaks or anything like that.

I would be careful with the drain bolts. Don't just blindly dial in the torque value and go at it, you might end up stripping it. Hand tighten it using the smaller 1/8" ratchet (allows less torque) and apply light force to tighten it. Common sense approach comes in handy here. Then you can check with the torque wrench if you so desire. The filter housing uses a big ass nut that is easy to torque down but the drain bolt is so small, torquing it gets tricky.
By the way, 25nm seems a bit too much. I would double check that value.

Put in 1L of new oil, reached for the 2nd liter and realized I had new drain plugs. I switched them our real quick but lost some new oil. Anyways, that was the longest oil change I have ever completed... |

Your calculations may have been wrong because i had to build a financial model in excel when i did mine My torque values are always : strength it takes to loosen is strength it takes to tighten plus one or two umphs! |

I feel like touching that torque wrench with your pinkie finger would just strip the living shit out of the nut.

New to this. Can you guys explain how to use a torque wrench on an object as large as the oil filter cap? Seems like wrench attachments are mostly for smaller things like lug nuts...

Don't bother. Just go hand-tight.
