hi guys

this is not intended to start an oil war lol
my question is two parts:

i have 2014 f20 m135i with 30000miles(48000km)

For a hot climate such as parts of south Africa (where Im from) I have been advised that a 5w40 would be better then running a 5w30 is this true?
My car will soon be full bolt-ons without a stage 2 turbo and will see the odd track day maybe once or twice a year.

secondly which of the following would you suggest (i can only run LL01 oil due to our high sulfur content in the fuel) or is there anything else recommend above these:

Motul 8100 xcess 5w40
Motul 8100 xmax 0w40
Liqui moly leichtlauf high-tech 5w40 (with ceratec)
Liqui moly molygen new generation 5w40 (can not be run with ceratec as is has its own unique additives built in)
Mobil1 esp 0w40

Sure it is.

What's wrong with the (Shell) ///M 0w40 (we all love so much )?

In theory it is not. It should be more suited to colder climates.

I included a link to South Africa BMW site in my previous message. Well, I did notice they provided no (grade) details and still they must offer something for the cars they sell and service!

"In theory" 5w can be better in hot climate from being less appropriate in cold weather. But you simply shouldn't bother with the winter grade which is just irrelevant in hot climate. BMW's ///M oil I mentioned is 0w40 only(?).

None. I would stick with the dealer's offer just as I do. By the way, last time they put 5w30 instead of that ///M 0w40 they had used previously. When I asked WTF they noticed my engine wasn't a M-Performance one and failed to explain why they had sold me that "excessive" oil before then, yet acknowledging that the ///M oil was available had I told them I wanted it.

There are a couple of threads around you might want to look at: F20 M135i CrankShaft Stuck and Can't Start and CrankShaft Seizure Repaired for M135i.
