what kind of extra maintenance do you recommend if I want to keep '23 M2 until 2030 or beyond? (besides the usual more frequent oil/filter and fluid changes)

thanks!

Honestly? Nothing really comes to mind. It's generally just the fluids, those that prevent wear (oils, lubes), those that can cause corrosion (coolant).

Almost everything else is wear and tear. consumable parts that you simply replace when they wear out. Tires, hoses, filters, etc. No special steps really needed, IMO.

It also matters more WHY you are asking. Answers are different if you are trying to preserve resale, vs. trying to keep the car running as long as possible.

You COULD PPF the car if you want to protect the paint long term. It does help the paint a bit, but it's probably not worth it just for resale value.

But really, your use of the car matters more than anything else. Avoiding salt or humidity, garaging the car, avoiding sun and bird poop, cleaning off bugs ASAP, cleaning and protecting the leather, driving smoothly, etc.

Keeping a car 7 years doesn’t require any extra maintenance

[kudos]

Just keep up with typical maintenance. Make sure you do oil changes on time. Rotate your tires / alignments when necessary. Keep fluids topped off when needed. I had my e90 for 15 years and I wasn't the greatest with maintenance and it still ran great when I traded it in. BMW's will last if you take care of them.

Keep the fluids fresh and surfaces protected.

When I buy a car my intent is to own the car forever. So I start out with proper maintenance in mind.

This involves an early oil/filter service -- at the end of break in but sometimes at the halfway point. (I like to add unless this is forbidden by the factory.) 'course the M2 has a factory scheduled and provided for break in service.

But with my M2 as with a few other car I had the oil/filter changed at around 600 miles.

I don't really subscribe to the 10K mile oil/filter service schedule. It is more than a feeling. Early in my Boxster experience -- for which the factory called for 15K mile oil and 30K mile oil filter (!) services -- an on the whim oil analysis at about 5K miles opened my eyes to how the oil had degraded. So I changed the oil right after the analysis and for that car (and every car since) every 5K miles.

Given I don't drive that much I instead change the oil every 6 months.

Before my M2 and its CBS system I'd change the oil in the fall -- before winter -- and again in the spring before summer. It so happens the M2's CBS wants an oil/filter service done around mid April (I bought the car April 14 of 2023) so I all I do is have an out of CBS schedule oil service done in the fall.

For the out of CBS oil/filter services I pay for these out of pocket. And I don't have the CBS system reset. This only gets reset when the car is in for a CBS service.

I have the brake hydraulic system fluid (and with some cars with a manual transmission the clutch hydraulic system fluid) flushed/bled every 2 years. Porsche called for this and I had an opportunity to find out the fluid does suffer some real degradation which in the case of one car resulted in a noticeable problem with clutch operation which also caused shifting problems. The clutch hydraulic system shared fluid with the brake hydraulic system. A hydraulic fluid flush/bleed put the clutch right and the shifting problems were gone.

So every two years the brake (and if applicable the clutch) hydraulic system fluid gets serviced.

Years ago my auto tech buddies advised me to replace the coolant every 4 years. This would extend the life of the cooling system hardware. Radiators, heater core, water pump (seals). I have done this and never had a hose fail. In one case even after 317K miles and 16 years...

(Might add a writer for one of the BMW car mags -- Mike Miller? -- was an advocate of preventative maintenance for BMW cooling systems.)

Drove several cars to 150K miles with not even a water pump or hose problem.

First water pump I had to replace was at 172K miles.

The water pump went bad but due to wear not seal failure. The pump was noisy, had some bearing play, but the seals were not leaking.

The flip side is in the case of another car -- a car I bought used and for its first 6 years (in the hands of the original owner) didn't have the coolant changed -- the seals failed at 100K miles.

Other wear items on schedule.

Accessory drive belt/serpentine belt.

Air filter (engine and cabin).

If I own the car long enough -- and I often do -- spark plugs.

Transmission/diff fluid.

So far none of my cars have had a factory scheduled O2 sensor or coils service. But these are wear items and I have over hundreds of thousands of miles gone through several sets of O2 sensors. That they needed to be replaced was indicated by a CEL and an error code (or codes) pointing at the sensors.

Keep the car clean outside and inside.

Use the car regularly. Cars "hate" lack of use.

And avoid accidents.

Follow the regular maintenance schedule. All this changing oil early, changing that early, etc. really just depletes your wallet. These engines and components are tested for hundreds of thousands of miles & the maintenance requirements are developed from said testing.

And I will add the CBS is way smarter than the owner is on what’s required for maintenance. It takes into account environmental conditions along with use and of course is programmed by BMW engineers that actually designed and built the vehicle and not some guy in his mom’s basement.

Would just like to confirm I am now living above the garage.

I had my 2013 E92 M3 for 8 yrs. She looked as good as the day I bought her with just common sense. Garage it, keep it clean and keep up the maintenance.

As with ships... they can if you wanna, they don't have to if you don't wanna. Let's not make it any more dramatic than that, pls.

Ok then, I’m declaring my garage in Arizona to be unisex.
The M240i (her) is parked left of the M2 (him).

I hope there’s no gender change during my summer absence.

You might ensure there is a car cover over at least one of them or you could come back to some small ones running around the garage.

But back to the OP. There are some items to consider if you want to keep past 2030 (70k miles) and that involves "lifetime" fluids - such as coolant, transmission, etc. But beyond that, the advice here is spot on.

Also, although I don't agree with the aggressive oil change intervals by some, I am not a big fan of 10k oil change intervals (personal decision) and prefer to be around 7000 mi, but you do it your way and we can peacefully disagree.

The garage has a seasonal supply of cardoms to prevent unplanned sub-compacts.

If you clicked on the "maintenance" link provided by Tag above, you'll see it's every 30k mi. The first change is covered as long as your 30k mi falls within the first 36 months.

Missed that. Thanks. I will only be putting 3k miles a year on my M2 so wonder if spark plugs wil be recommended at 3yrs (3rd service) and only 9k miles. Etc etc

There's certainly a case to be made for just following the manufacturer's service schedule.

But professional auto techs advised me that shortening the service schedule intervals was well, advised.

They impressed upon me in the engine oil/engine (or transmission fluid/transmission) partnership the oil/fluid was the sacrificial item. The idea was not to run the oil/fluid to the ragged edge of its endurance.

I have been having the tech collect a sample of the drained oil along with a sample of oil he is refilling the engine with and send these out for have analyzed. The first samples I received a report. But the last pair of samples I sent off I never got the reports back. Contacted the company via email and never heard back.

Next time I'll use Blackstone.

I want to see to what degree the oil has degraded.

Until then I'm not quite willing to rely on the CBS system just yet.

I have owned 10+ year old cars that looked new just by doing maintenance and keeping them clean.

CBS on my X3MC almost always calls for oil changes at 7k miles. It’s really like 8000 miles, but I bring it in the second it calls for service which is 1000 miles before needed. 5k seems ok, but anything before then is just throwing money away (IMO).
