BMW and M Power Owners

I’m 6 months in with my G82 M4, which is now about 9 months old, but I have a question that’s been nagging me.

It’s done a total of 11k miles, it says the service interval is 20k miles, (so next one in 9k or this Nov) but I’m thinking “really?” 20k miles between oil changes?…

I’m tempted to just take it in to get the oil done (will be 10k since it was last done at its run in service)

Or am I worrying about nothing and should just stick to the 20k schedule?

(All google results seem to suggest 10k miles…)

Just do it.
Won't harm it.
Will be benefitting it. Plus if you do it at BMW.. likely keeping its value higher lol

Kinda what I’m thinking tbh,

I can at least just get the oil and filter done, then take it in for its main service at 20k… won’t do any harm I guess.. and yeah I’m just get it done at a main dealer.

Booked her in for tomorrow, oil change and filter at the local Sytner, piece of mind if anything lol.

The engineer in me says BMW know what they’re talking about and if they say 2 years or 20k miles, then there’s no point doing it early.


The cynic in me says BMW are attempting to reduce the longevity of the engine in an attempt to ensure there is a higher turnover of cars and fewer older cars for sale.



Personally on an M4 I’d be doing an oil change every 10k purely because it’s an indicator to the person you sell it to that you care about the car, not just what the computer tells you.

For sure.

I'd say do it anyway. A buyer of that car in the future would surly be more tempted if it had interim servers no? I would be more tempted than not

I do my oil more often than the car wants but the tinfoil bit of knackering engines is just that.

Imagine they wound up with the reputation of their M series engines routinely exploding? Which for all the jokes just isn't the case.

The engineer in me knows they’d be clever enough to model the longevity based on frequency of oil changes. They wouldn’t blow up prematurely, they just won’t achieve the 200k miles they’d probably otherwise be capable of.


Tinfoil hat moment I know, but this is a capitalist world which rewards companies for making as much money as possible with complete disregard for the environment and people.


DuPont case in point.

The irony being I'll bet once they go past being 3 years old they either fall into the hands of undesirables who stick halfords tat all over them and then write them off or people who wrap them in cotton wool and ignore the service intervals anyway.

So you'll never actually know. Which undermines the whole point :)

There are plenty of external pressures for wanting longer oil change durations, bean counting fleet managers being just one of them.

I'm happy to run my company car to the 20000 mile interval (circa 10 months of use) but if it was my own car it would be getting swapped out after 10000.

The (F87) M2 is more than "just a 2 series with posh M bits". Using your logic, you can apply that to any of the M cars, or indeed Audi RS and Mercedes AMG models?!

Surely an XM would be the best SUV for you as it's a bespoke M model? ;)

I don't disagree, re AMG/RS/M upgrades.
 
  • Wow
Reactions: mjt

How many fleets are running cars like these though? I can't imagine your average fleet manager picking a BMW M4 when otherwise he wouldn't have because it needs servicing a bit less often.

Wow that's an impressive looking M2, didn't realise you'd swaped from the M3.

Thanks mate. Few months in now and still no regrets. RIS was done the other week. It's an impressive car, I don't miss the F80 at all, I thought I would but the G series jump is massive in so many ways.

In before haters gonna hate.

It's incredible how much of a step up the G series is from the F. If you drive them back-to-back it's mighty impressive. Going back to my M2 after spending half a day in a new M4 was rather depressing.
I can't afford a G8x and I've got used to the M2 again so it'll stay a dream for now. On the plus side, the G models are selling like hot cakes so there'll be plenty to choose from in a few years ;)

Probably confusing “design for failure” with “not designed to last as long”

They’re subtly different but one is an intent to get an item to fail after X amount of time - hugely costly, and the other is going “seems to last an average of X hours of operation, that’ll do” attitude.


I think there’s an essence of that, but also, we must also not forget the fact that newer components have much stricter tolerances, as required by the higher performing parts, which means it is much easier for a component to go out of tolerance and, hence, fail.

You don't seen to understand that lifing is about creating parts that last 'at least a certain amount of time'. That's how it works. You assume that you have a crack initiation feature that is just below the minimum size that can be seen by inspection and sitting in the highest loaded feature and workout how long it will then fail from that point.

However, manufacturing methods have improved so you can make things to tighter tolerances. More importantly there is vastly more information from manufacturing so that the design and stress groups know what these tolerances are. If something can't be made to a required tolerance you either change the design or create a manufacturing process that meets the tolerance requirements. Even better you actually add the tolerances in at the design stage and analyse the component through the complete tolerance sizing, something that has been done for the last 30 years or so. This then enable you to work out which are the important tolerances and which ones can be relaxed. You also add in the uncertainty for the loads that the component is subjected to and, again, work out which are the critical ones.

This is it, cost cutting everywhere which affects longevity and durability.

I should have worded it better... The quality of materials inside alone have dropped in quality, compare a 90s/00s car to a modern equivalent.

How do you explain the fact the the B58 will happily go to 700bhp on stock internals?

Material quality and knowledge is vastly better than it was 30 years ago, as at the very least you've got 30 years more materials testing data. As with the design and loads, you can add material uncertainty into your analysis models.
 
So after being quoted £256 Inc vat on the phone from BMW for oil / oil filter and air filter. Ita apparently £350 . What is an environmental charge ???

They can't just quote one price on the phone then increase it when you here

Two sytner BMW dealerships I phoned and they both quoted £256 Inc vat

They have gone to apparently listen to the call


Edit: mistake on their part :D. I also love how they said there is no oil change scheduled on my car for another 15k miles..
