Perhaps you don't intend so, but your post come across as slightly argumentative. Understanding there is some language barrier, but it comes across as some one who ask a question and then argues with you about it when you answer.
you might be right but i wasn't intend to. maybe my mistake was that i tried to write all my questions, wrong or wright ,in one post.but i did it so that i wont make many new topics, useless or not. i explained from the very first posts that there is a language thing and i said i respect all of you. i don't understand how could i be misunderstood after that explanation. i didn't argue, not in a impolite way ,at least i wasn't intend to, writing spirit might be misunderstood sometimes, just quote many opinions from other experts, wrong ok, but opinions.i know you guys maybe are tired of repeating the same things all those years but i am not the only one who posts such wrong info.
I realize you are trying to select the "best" oil for your use, but understand the available oils, the car, the engine and the locale are unfamiliar to the majority of posters here.
so its a domestic, US forum only. i thought ,reading post and from other European members that this was a topic which says
European and import oils. thats why i posted there.if thats not the wright topic then please which one is it? i gave you the info ,you need. the engine is familiar but in larger CC in US ,maybe old now ,yes, and not so popular there ,but at bimmerfest( i think eddy posted there too ,if not i apologise for the misunderstanding) bimmerworld,1addicts ,is popular and they are mostly US citizens.so i thought its familiar here too. some of the US members at these sites ,maybe are members here too. and if not ,then i gave you all the technical info, temperatures, problems of the engine and of course specs ,approvals and norm from bmw which happen to be both US and european suitable, A3/B4,LL01 a US norm and C3 BMW LL04 . so i don't see a reason why these are unfamiliar to you . the first norm is what you use and second norm ,there so many topics and posts about it ...and i am not like other guys here who write a question which is the best oil..i want to know about oils and how they work in my engine.i will be the one who will decide which is the most suitable, not the best, but with the help from you.i mean if i wanted a general opinion which is the best and so on ,i would probably stick to my region bmw forums, who all speak and talk about the same things.they dont go deeper like you guys.they dont know that a 0-30 is more sofisticated oil than the 5-30 they all use.if you read european forums of any car brand, there is constantly an argument between ambient temperature and engine temperature, which one counts most for selecting the wright viscosity. so i got tired and they all talked about bitog ,so i came here to clear myself things out.and nobody ,i mean nobody ever mention an info about altitude, which is a good and legit info.i googled it myself. so blame me for my wrong knowledge ,but don't blame for coming here to clear things. and if you are tired to do so ,then give links where i can find the info you are tired to give yourself where to find it in this forum. as i said and proved to you from my links ,i read the forum ,but its impossible to read the whole one .
Yes it is an oil forum and yes is a OCD oil forum, but but your question is inherently rooted in opinion. So you're getting widely varried opinion.
thats not bad, varied opinion.just with civilised and polite way.i am a very kind and polite person and thats what i expect from the others. well a very known ancient Greek philosopher, maybe you have heard of him socrates, said..'' asking is the way to learn the truth and to seek knowledge''..
In order to find the best you must first define best.
as i said i want the most suitable, the best for my engine which has some weird operation problems and i want to make sure that don't come from wrong oil choice. i explained that from the very first begging. now, if i come to the conclusion that its not the oil or the viscosity that may play a part to my engine problems then any approved viscosity or brand is welcomed. i thought that this forum splits hairs.eddy said that he will decide about which oil he will use according to the position to the moon. so thats not complicated and my simple questions is what the forums has a problem with?
That said returning to your original question, I would do the Specific LL04 if LL04 what your owners manual calls for, just import enough of it to last you a good while and store it properly.
if you mean the motul one, this one is very expansive to order from abroad.things were quite affordable when england was in the european union but now after the brexit all the other european countries sell in higher prices and shipping costs.so its not worth it.thats why i am trying to compromise with domestic market.besides i think that specific might be deleted as an oil code. motul x clean 5-40 has the same specs more or less.thanks for your help anyway.
