I’m sure this topic has been done before in other guises, but would appreciate the advice.

I own a 2019 BMW 530d M Sport, that is used almost exclusively for longer journeys of approximately 150 miles. It was serviced at a year old (July 20) and 11k.

The service advice on the computer and speaking with the dealer is that it just requires in July a brake fluid change. The mileage will be 21k next month and I was wondering whether I should also have the oil changed, that is additional to the service requirements.

I generally replace my cars at 4 to 5 years old so at most I would have this for another 3 years.

However with all this EV legislation, I probably won’t be changing it as I’m not keen on EV’s and wouldn’t want to be investing in a new 3.0 Diesel just 5 years away from the cut off.

Advice please on the oil change.

Every 10k or annually (whatever comes first) if your keeping it long term.

Wouldn't even go off the computer for oil change intervals, BMW's can be pretty sensitive to oil changes so make up your own regime.

I have a 2019 520d and keeping it for the long term. I’m just sticking to the recommended schedule as per the computer. Don’t see the benefit in doing it more frequently

Agreed. I keep to the schedule, I’m not a ‘must do it anally, sorry, annually’ type.

I think the combination of an oil quality sensor (determines the level of contamination by measuring the delectric value of the oil), and what seems to be a pretty sophisticated algorithm that the BMW's CBS system uses to determine service requirements works pretty well. My M140i did a lot of long motorway runs, and wasn't driven hard all the time, and asked for its first oil change at 19k. A friend had an identical one that he regularly used on track, and which did quite a few short journeys, and his asked for its first oil change at 7k. Both were triggered well before the 2 year time limit, so it was oil quality and the way the cars were used that determined the interval.

That said, I do think exhaust particulate filters add an extra level of oil contamination. I checked the oil on my i30N this morning which has done just under 3,000 miles since it was last serviced. The oil is the right level, but fairly dark already, and it absolutely stinks of petrol. Of course the contamination of diesel engine oil with fuel is also well documented, to the extent that it causes oil levels to rise in some engines.

There is nothing complicated about how a car decides whether it needs an oil change or not, its down to the driving style that the ECU picks up on.
Long distance constant driving is far better for your oil than short stop/start driving, if you feel the need to change the oil then do so, it will be better than leaving it in there for another 10k miles.

Danger, 5-page bore-off incoming.

Ask about budget tyres while you're at it why don't you? biggrin

Used to change religiously at Mfr intervals,then using synthetic extended to 20+k no harm to last two motors 180+ and 160+ k miles

Thanks for the replies as regards the oil changes.

I’m absolutely fine regarding budget tyres, all 3 cars and the motorbike have matching premium tyres thumbup

However many thanks for thinking about my motoring requirements beer

To keep your mind at rest the others, a Kawasaki ZX6R, Mini and Alfa all get annual oil changes.

Whilst keeping with the times regarding (CBS) I’ve gone to changing the oil (Rock Oil for Agricultural products) on my Honda Lawnmower (not a sit on) to Bi- Annual nerd

You could always do what the Americans do and send a sample of the oil for analysis.

There's one thread where an owner sampled the oil every 1000 miles and really wanted to see how long it could go for - IIRC he got to 13K miles and he just couldn't take any more! And he admitted he'd changed the filter at 10K.

As its a long termer, hows about buying 25 litres of the correct oil when on offer and half a dozen filters when you see them on offer and slipping in a crafty halfway house oil change yourself between the main garage (assuming you use one) services.

25 litres of the best oil will set you back what £120 tops plus 4/6 filters likely to be £30/40, so thats £150/160 for at least 4 oil changes (assuming your sump doesn't take more than 6 litres), looks like a good investment to me seeing as that's probably less than the cost of single oil change at the main dealer.

I know those who don't get their hands too oily suggest this type of good maintenance is a waste of time and money, funny how you find people who do get oily regularly tend to a different view.
Keep the receipts plus a diary of when you do these changes, when you come to sell the knowledge your car has been properly serviced may well see it being snapped up by a friend in preference to some dealer serviced item that's not seen fresh oil for 20k miles a throw.

Sounds good to me.

As a keeper, I'd be changing it annually, especially in a sophisticated diesel, and a very nice one like yours.
Many mechanics will tell you the best thing you can do to prevent problems in a diesel is to frequently change the oil.
I guess manufacturers have had to adopt this approach for environmental reasons, they also only require their engines and turbos to be reliable through the warranty period after that its of no concern to them.

The cynic in me thinks manufacturers come up with these extended service intervals to please the fleet, rental and lease market's and the pcp hand it back in 3 years customers too, none of these give a tuppeny one whether extended servicing, or in the case of gearboxes all too often no servicing at all, is detrimental to the reliable long life of the vehicle, and sadly too many manufacturers appear of the same mind.

Exactly this but it's nothing new.

BL did something similar half way through the SD1's life, along with the facelift they suddenly doubled the oil-change interval from 6,000 to 12, 000 miles. Publicity was all about reduced servicing costs over the industry-average 4-years, and the advertising then showed comparisons with competitors. There were no mechanical changes, simply a doubling of the oil-change interval (and plugs IIRC). All about cheaper cost-per-mile for fleet users, nothing else.

I'd prefer it if they reduced service costs by halving their labour-rates.
