0w oil instead of 5w to increase timing chain longevity ?
Discussion
Hi,
I want to buy a BMW X3 F25 with either B47 or N57 engine. I would be more excited of course with N57.
Since BMW uses timing chain i was told that to maximise chain longevity it would be good to use 0w oil instead of 5w because timing chain tend to wear at cold start until it warms up. I live in France, in moderate climate 5w is what most people use here.
What do you think ?

Stick with 5W30 - you'll be fineI want to buy a BMW X3 F25 with either B47 or N57 engine. I would be more excited of course with N57.

Frequent oil & filter changes are paramount, so once per year at a minimum unless you do high miles, and then do it every 6 months
Both engines are solid if looked after
Mine is now on 122k (miles) and is absolutely fine, serviced a couple of weeks ago and the bmw dealer says they always listen for rattles
They did say that cars that have full service history, regular oil changes and have been looked after don't seem to have issues
The only ones they've seen issues with are cars that have missing services or have been neglected
I'd say as long as you buy one that has a full BMW history you'll be fine

It won't make a difference unless you are in areas that suffer from extreme cold in winter. I think 5w is tested down to -30 degrees C, 0w a bit further than that. As Dan said, frequent changes and using a BMW spec oil is more important. Petrol cars are LL04 spec, not sure if the same for diesels.

Yup; LL04 for the DPF health etcPetrols can be LL01 as well; but not dervs
