F10 M5 oil usage

[BobSaunders]

Hi,

Anyone else with an F10 M5 care to comment on engine oil usage? Mine seems to be chewing (drinking?) it.

I popped in a couple of litres a couple of months ago which put it at mid/high level, and already i am getting a warning light saying it needs more.. Unsure on amount as not had time to place it on the flat, but i suspect it is below the minimum amount.

Mine uses f-all, I mean hardly a drop (12500 miles in so far)

Usage varies massively, check the link below: -

For the record mine's still holding steady (after 52,000 miles) at a litre every 3,000 miles with 90% motorway driving.

Thanks for this. It is possibly due to the car not warming up completely on the run into work (when i pitch up).

I am up to 19600miles on it.

My M6 (same S63 engine) has used nothing at all (electronic dip stick still says full) since the last oil change almost exactly 6,000 miles ago.

Consumption is massively influenced by how the engine has been run for the first 50-100 miles. If you're too gentle with it, then the rings don't get seated fully and high oil consumption results. You need plenty of moderate revs (when warmed up of course) and to use plenty of engine braking.

Purchased second hand. No idea about previous ownership (beyond V5 / BMW history / numbers still stored on the quick access buttons on the radio..)

I have done 20,000 in mine, which I had from new. I would estimate I have added 5 top up's plus the oil service in that millage.

Oil usage has reduced over time as well.

Mine's on 8k miles (that includes a fair amount of Track miles) & not a jot of oil added.

I'll be getting an oil change at 10k miles as i feel for a performance engine, 18k miles between oil changes is too much. I reckon i may have to top up 1/2 litre before the old change as the display has the old between min/max.

I disagree with the mileage between oil changes for two reasons:

If the car needed it BMW would change the timescale

It's a lease car, why bother?

I am on my 2nd m5 f10 my first one had a real thirst for oil 1ltr req every 1.5k miles my 2nd m5 clocked 12k miles before it need any oil ! I think the later m5 f10 must have had something changed on them to stop the thirst for oil

Interestingly in other markets the oil change intervals are much shorter! The shortest is just 8 months or 12,000km between changes.

Are you suggesting the M5 has different intervals in different countries?

[steakandchips]

I've done almost 11,000 miles and I haven't put any oil in. I've done a mixture of 30 minute drives around London at no more than 20mph and a lot of long motorway drives in Europe cruising at 130mph for two hours at a time. Sometimes my car doesn't move for two weeks or three weeks at a time.

I've no idea why it's never asked for a drop of oil but I did try to run it in as per the manual with just a couple of instances where I went to the top of the rev range.

Yes, there are. There are several different intervals depending on the market.

S8KAA Oil-maintenance interval - 24 months/30,000 km
S8KCA Oil-maintenance interval - 24 months/24,000 km
S8KEA Oil-maintenance interval - 24 months/12,000 km
S8KKA Oil-maintenance interval - 18 months/15,000 km
S8KLA Oil-maintenance interval - 12 months/15,000 km
S8KMA Oil-maintenance interval - 12 months/12,000 km
S8KPA Oil-maintenance interval - 8 months/12,000 km

UK cars get S8KAA.

Surely the engine is the same so it might be differing grades of oil used in various countries (much like petrol differs)?

[RichardM5]

I would guess it's down to fuel quality and climatic conditions, I'd have thought that the oil would be identical or very similar. Being cynical you could think that the intervals are specified to get the car through the warranty period and after that they don't care too much. But to me, unless you have a lease car, it indicates that interim oil changes may help things later in the life of the engine and certainly won't hurt.

15k miles - 1 litre oil. 60/40 mix between motorway and town driving.

[RSaint]

Mine has done 13k now and I have just added its first litre of oil.

I'm sure the car 'can' survive 18-20k oil change intervals, but Lease Car or not i want it to run optimum performance & i unlike most track my car so i want everything running to it's highest possible level. The oil changes i choose will be carried out by an Indy & won't impact the service schedule as the computer won't be reset. More is better when running a performance vehicle & most tend to agree with such vehicles.
