Probably a heavy 30, it's less susceptible to shear because it has a lower viscosity spread than the 10-60. What shears are the VIIs in the oil, which are additives that create a multigrade oil in the first place from a base stock.
I would not be so sure M1 0w-40 is not up to the task. M1 0w-40 is used in track applications for Porsche GT3 (Mezger and 9A1 engines both) and Nissan GT-R. |

This oil "*Should not be used in BMW gasoline engines outside of the European Union". http://msdspds.castrol.com/bpglis/Fu...%20English.pdf So thats not very encouraging. As long as its an " LL-01 BMW Synthetic Oil for BMW M vehicles" then it should be fine. Any old "non M approved" LL-01 say from Bulgaria not so much.

Compared to the E46, the E92 appears to engage the "cold engine" rev limiter much more often - all it takes is a few minutes with the engine off. Additionally, the time to get fully warm is longer. The engineers appear to be telling me that a gentle and long warm up is vital.
Given the additive and non-reversible nature of bearing wear, the cumulative effect of going up the revs (maybe as low as 3-4k) with meaningful throttle immediately after engine start can be significant even a few thousand miles in (20,000 miles still represents hundreds of starts and opportunities to cause accelerated wear to the bearings). I plan to stick with the 10W-60 and simply be careful to keep the revs and throttle down until the engine is properly warm (and be especially careful during the first few minutes of operation). |

As you may know tuners can decrease the interim warming up period redline even lower than the stock value (which itself is a function of engine temperature). Although I'd never advocate really high loads, WOT or redline during the warm up period when ones redline is being actively limited to below 8400 rpm, I also think if warm up was that critical ("vital" as you say) BMW M simply would have implemented a lower warm up redline (lower at any given temperature).

I have a light ticking sound at idle, when the car is in neutral (6MT). Otherwise no ticking. Is this normal? I'm approaching the end of my extended service contract and am getting worried. Thank you in advance.

tailgate, It's pretty normal to have the steady valve lifter ticking on this engine at idle. If you are worried get a blackstone-labs oil sample done on your next oil change to check for wear of the rod bearings. This video below, I believe, shows a sound which is not normal to our engines. It starts around 4 seconds into the video. Note the random ticks. Guys, Please correct me if I'm wrong.

Bearing noise will be way more obvious than light random clicks. I do suggest tightening spark plugs perfectly to spec each time as plugs too tight or too lose can make all sorts of clicking and ticking. Happened to me as didn't have plugs tight enough. I used to use qharter turn past hand tight but learned from NGK that 2/3 turn past hand tight is correct |

I asked before, but didn't really get an answer. Can anyone advise on how often rod bearing issues are catastrophic and require a new engine? How much would a spun rod (is this the correct term?) cost to repair?

Yes but sounds like you've never done plugs yourself. I've changed my plugs every 10k and I'm very comfy and there is no way to get torque wrench to the very back plugs and nearly impossible the third ones. Maybe with the exact righttoo. I was timid to strip the block initially so iI didn't tighten enough. Then researched and 2/3 correlates to BMS torque spec as I tried it on the front plug where I could fit torque wrench so now I I use 2/3 turn each time

It's recommended inspection/replacement at 10K only for supercharged applications.
