hi people !
i buy a mini one 1.6i from 2005 and i wanna do a good check up to the car. but i have a question that i cant see nothing that tells me like " is that ! "
Well i buy a castrol gtx 5w40 , because i have made resources and no one have the right answer for that ! some guys says is better the 0w30 others the 5w40.
In the manual that i have in the car dont talk about the SAE itself , on talk about the certificate , BMW longlife 1.
So this oil have that certificate , but i see people saying that is good for warmer weather . I check the SAE tables , and the diference is the 0w30 can do from -40 to +30c and the 5w40 do from -30 to +40 .
so i think isnt a big diference there , i never had temperatures in scontland below -15 (with realfeel , witch is always higher ). soo, if i put this 5w40 will not burn my pistons rings in the starts ? or something else ?
I wainting for yours opinions !
Cheers mates !!

thanks for your reply !

If the manual says 0W30 and Castrol also list 0W30 then I would stick to that. Just do engine oil change every 5000/6000 miles.

That's the problem, the manual dont say is 0w30 it's say that's need to BMW longlife only. Inside the ll01 you have from 0w30 to 5w40... That's my issue....

I purchased a brand new R50 in 2004 and finally sold it in 2016. It was my pride & joy.
I always used mobil1 ESP 5w30 in it. I also changed the oil every 12 months/ 5000 miles. A great habit to get into.

I think it depends on age/climate, 0W30 for new engines/cold climate, 5W30 for average, 5W40 for hot climate/higher mileage.

My preference is Castrol Magnatec 5W30, bought in advance on the cheap whenever I see an offer. I'm a sucker for the advertising, but realistically any decent grade synthetic 5W30 will do (Eurocarparts, Halfords, etc, but they are not necessarily cheaper), regular checks & changes being more important than the exact brand of oil

Soo in the end, don't matter know about the certificates? Becouse the oils are you talking about they BMW ll04... That's my problem where.... Thanks a lot!

If the oil meets or exceeds BMW minium recommendation then you should be fine.

From what I read and seen BMW-LL-04 supersedes previous BMW specification.
