Might be a dumb question but, Do these new BMW's tell you to change the oil sooner if needed before the 10K mile mark? Basically will it detect if it needs to get changed sooner before the normal service? I honestly don't believe in changing the oil at 10K miles especially in NYC Driving, especially with the auto start/stop feature disabled

Thanks

I could be wrong but I think the car adjusts oil change intervals by recognising your style of driving.?

Believe it's preset at 10k. At roughly 8k, a yellow triangle should appear in the instrument cluster as well as the idrive, warning that an oil change is coming due - at least that's how it was for my '19 x3m40 and my '20 x3mc. I'm 99% certain the oil change timing doesn't adjust itself to driving patterns.

I have basically the same question. I got a 2020 M40i with about 6K miles that I plan on keeping long term. Not sure wether to wait until 10K or change it at 8K and get the free one at 10K.

This is correct, "Conditioned Based Service" is how BMW terms it. The cars electronics monitor engine RPM, driving speed, etc. and compute service interval- this has been incorporated into most models in some form going back to the late 90's.

However many enthusiasts change oil snd filter regularly at shorter intervals; I do my much of my own service/some repair work and change oil/filter at 7,500 miles. Most generally agree that with the modern synthetic oils a 10K interval is very acceptable.

Wait, theoretically if I take my car to the race track every single weekend and race my BMW for hours with high RPM and acceleration and all that, the car will alert me that I need an oil change sooner than the preset 10K miles?

Correct; the 'harder' you drive the car the sooner the CBS will alert you to change the oil; I may be wrong but I don't think there is a 'preset' (fixed) 10K oil change interval, as far as I know the interval is continuously varied based on the CBS system and you are alerted to do oil service accordingly via iDrive.

I would like to see this being state by BMW. So I can

[Wgosma]

I believe the car's owner manual explains the CBS system, though perhaps not in much detail.

Hey freshxdough is this accurate?

[freshxdough]

Condition Based Service is supposed to adapt the oil change interval based on driving behavior. On the newer vehicles such as F and G cars I honestly haven't seen these numbers change much so I'm not sure if they implemented a more strict mileage/time based interval. I do remember on older cars like E90 and such that you could see an oil change due sooner probably due to the customer driving behavior.

As far as our cars go, I've always seen 10k oil change intervals. I prefer to do 5k oil changes on my B58 to ensure fresh oil is always in the engine.

[freshxdough]

5k mileage oil changes. Do not reset the light. Only reset the light at the 10k interval or you will mess with your vehicle check and spark plug interval.

Thanks. All my late model BMW's have been spot on at 10k intervals, regardless of my driving habits. The only time I had it changed sooner was for my current x3MC which had a 2k oil change requirement

I do a lot of road tripping/highway miles...my CBS change interval is well in excess of 10K miles (but I DIY oil/filter around 7-8K). I would expect that one who does lot of short trips/stop-go city driving would see interval < 10K.

Driving your vehicle hard is easier on your oil than driving like aunt matilda.
The UOA above is nice. Also letting the tach bounce of the redline is good vor the vehicle. Now it you have 50 000 miles on it you heed to work up to in. Also don't floor it quickly (especially for an auto)..take about 2 seconds to floor it and just watch it bounce off the RL if you can safely do it.

Both of my subarus saw frequent redline after 200 miles of driving. Neither use any detectable oil. But bear in mind all engines must of necessity use "some" oilm

[chicagofan00]

I've had it tell me I'm due for an oil change twice now in 16k miles. So yes, it is conditional.

My mileage schedule is the following:

• 500kms per week
• Once a month I drive up to my cottage in Quebec - return trip is 1,150kms

My oil change recommendation pops up on my iDrive approx 2kms before the scheduled 10k

[animal.style]

FWIW I used to have a 2 mile city commute. I had my oil changed at around the first 4000 miles. The notice when I started my engine now said service is due in 9000 miles. For the next few hundred miles, the notice sometimes went down to 7000, then back up to 8 on my next trip. Then my commute changed to 50 miles hwy. I got the overdue notice at just before 14k and I had it serviced again. I'm at 16k now and the notice says due in 8000 miles. So in the end it looks like it's sticking to oil change every 10k. Personally I prefer 5-6, especially since it's covered under warranty.

[Dandle]

In the UK the B58 oil service intervals are set at 18000 miles or 24 months. Mine called its first oil change at 15k miles after adaption. My F11 530d was the same and required a service at similar mileage each time.
Its personal preference if you want to do them sooner but the oil is perfectly capable of these sort of intervals and has been for the last 20 years or so. The days of seeing cars driving along burning oil due to engine wear are long gone. Oils and filter technology has moved on a lot since the old mineral oil days.

[ChipsRideBikes]

Service techs at my local shop said if you drive like an "enthusiast" change it every 5k mi. the 10k is so BMW can save money on leases and for Ultimate Care. That all being said tell them not to reset the service monitor... i repeat DO NOT let them reset the service monitor. 2 things- as already stated it will mess with other measurements on spark plugs, etc, but more importantly, YOU will have to pay for every service. BMW will only pay "when the car tells them it's due" for service. Otherwise you will just be stuck in a vicious cycle of paying out of pocket.

[g0t2bmiirii]

I guess i should just change it myself at 5K miles then when the light comes on to do the service. Just to bring it to BMW for the free oil change. Sounds like the best option for now

[satz]

I think in Australia the oil change intervals are set similar to what Dandle said above for UK. 2 years, though not sure about mileage, whichever comes first.

My car's due for oil in June, exactly 2 years after it was built. Although it would have only done about 7,000 miles by then.

Is there a guide to DIY oil and filter change on the X3 b58s?

If you do change oil more frequently (at home), and don't reset the oil service indicator, will the car automatically detect fresh oil, or will the prompt still appear at fixed intervals?
