Motul 0w40 8100 X-Max
Let me just begin by apologising in advance for creating yet ANOTHER oil thread. However I have been doing heaps of searching and haven't come across anyone's honest review and opinion on using Motul's 0w40 8100 X-Max as my daily driving oil. It is on the BMW LL-01 list, so it's in the clear. I just wanted to ask what the benefits were to using this oil. I live in the Bay Area California where the temperature fluctuates from the low 40s in the winter to about 85+ in the summer. Also my car is under warranty, but I feel I won't cause any stir with BMW since it is on their LL-01. I would appreciate your input.

many will tell you what im about to say but might as well get this point out of the way....
its not 100% clear that LL-01 is on the list of approved oils for the S65. the bulletin from 2013 can be interpreted many ways, and when dealers or BMWNA is asked directly, they say 10w60 only. thats at least my impression from the countless threads on the subject. just getting that out of the way... this coming from someone who literally 5 hours ago switched over to mobil 1 0w40 only drove it for about 30 mins on the way back home, but car felt pretty much the same. note : oh, and from what i read on the subject... when the dealers / technicans click thru the inpa screens it still list 10w60 only. i could be wrong, but a few people mentioned that fact.

This is my observation (I'm currently running M1 0W40), if you must run a xW-40 oil, M1 0W40 has better technical specs than 8100 0W40. M1 has higher HTHS and TBN, which makes it more shear stable when you flog the motor, and it's more serviceable. 8100 5W40 x-cess is more comparable to M1 0W40.
I also notice from many oil analysis reports that fellow owners are getting good wear results from the newer 10W60 Edge Pro with titanium and higher moly. It's up to you to decide. |

I don't think there's a call for 0W-40 in Northern California climates even on our engine with its tight clearances. 0W is intended for subzero temperatures. But if you do feel the need, I would stick with Mobil 1.
Mobil 1 0W-40 also meets LL-01 (http://www.mobil.com/USA-English/Lub...l_1_0W-40.aspx), but LL-01 oil for our cars is still in an approval gray area at best. Take a look at this thread: http://www.m3post.com/forums/showthread.php?p=16214940

Why change oil if what you are using is tested and doing fine for thousands? Price? Peace of mind? I though about changing myself but why alter the oil that I/you have been running on for thousands of miles? Don't see the need in it. Not trying to start an argument, just curious.

So let's get this straight. You want to change your oil to a non approved oil due to a thread of a motor letting go. But your car is under warranty too? Believe that if your car were to blow up running anything other than 1060 you'd have a very hard time getting BMW to foot the bill. I would think they would deny coverage

Ignoring the LL-01 compatibility controversy, I will say that the X-Max 0w40 is a pretty unremarkable oil on paper and in operation. I'm sure it would work fine (since it has LL-01 approval), but given that it is not readily available at brick-and-mortar stores, the extra cost isn't justified. The additive pack is mediocre, the specs are mediocre, and the basestocks are relatively low-tech. You can do much better for the same or less money. If you want to stick with LL-01 oils, your best bets for off-the-shelf are going to be Mobil 1 0w40 or Pennzoil Ultra Euro 5w40. Both can be had for $6/qt or less when on sale at most auto parts stores.

Even if it's 65 degrees at night where you live, the 0w will always be better at startup than a 5wXX or 10wXX. Also remember that these cars are water-cooled and not air-cooled, so the other fallacy of "thicker is better for warm climates" needs to die too.

M1 0w40 is quite stout and can take high-temp/high-stress use just fine. It's not exactly a direct trade-off...you truly can get excellent low and high temp protection from a single oil these days. Don't believe me? Go look at the countless UOAs.

That's what has to be weighed when considering using 0W-40 over the 10W-60 that BMW has unquestionably approved.

In the interest of avoiding yet another 'OMG GUYZ LL-01' thread, I'm trying to discuss the merits (if any) of X-Max 0w40 over the breadth of other similar oils. You're trying to turn the discussion back into another LL-01 debate, which I think we've already beat to death elsewhere on this site.
