We have a 2012 520d with the N47 2.0 L diesel.
Wife uses it for frequent short trips locally about 5 to 30 minutes 6 to 10 times a day. This seems to be hard on the oil, batteries etc.
We live in South East Queensland Oz and the very coldest night of the year drops down to 10 C but normal termerature range is 15 to 30 degrees C year round.
BMW spec is of course LL04.
I only have 2 options for BMW certified LL04 and other options which 'meet the requirements of'.
The certified options run $110 for 5 litres.
Having recently just had one of above certified options shear down completely to the point the timing chain tensioner was not working when hot before factory 15,000 km OCI, at 13,000 km, I am rethinking oil for this engine.
It's currently running 5W/40 uncertified 'meets requirements of' LL04 which the engine is quite happy with, but this was still $67 on sale for 5L.
The vehicle currently has 73,000 km.
I am trialling 5,000 OCI now which is 6 monthly.
Oil fill with filter is only 5.25 litres which in my experience is less than normal. My work truck has a 2.4 litre 4 cylinder diesel with 8.4 litre fill and 6.5 L + is my experience with other similar vehicles. This is running easy factory 15,000 OCI being refilled by dealer under warranty with 'wrong' 10W40 Valvoline Professional, however it's mainly highway k's.
I am of the view that in my climate, as experienced with all other diesel light commercial vehicles in our fleet, a slightly higher grade oil would be beneficial such as 10W/40. There is no LL04 in this grade and regardless I only have two expensive options one of which I have lost confidence in.
The N47 is also known to have timing chain wear issues and I wonder how much is related to the thin LL04 and extended 15,000 OCI.
What I'm saying is; I'm out when it comes to LL04 and factory OCI. My wife is also good at ignoring distressing mechanical sounds and I want the extra safety buffer a higher weight oil has (all things being equal).
I see many other oil options which appear to meet or exceed LL04. Like C3, but these oils typically are 5W/30 grade as well and carry an inflated price tag.
However, I have access to many excellent oils at a good price with API CK-4 and E9 certifications in the desired 10W/40.
Looking at specs they appear to meet LL04, mid saps for DPF, HTHS min of 3.5 etc. TBN, stays in grade etc.
I feel like 10W/40 CK-4 would be an upgrade for this car and with 5,000 OCI would give me the peace of mind I'm doing the best possible wrt timing chain wear and overall wear (despite being overkill) given my wife is notorious for ignoring mechanical distress.
Is CK-4 a valid substitution for LL04 in my situation?
