Late running in service

[MisterCorn]

As these cars get older, and the engine is no longer covered by BMW warranty, how much store would you put by the mileage that the running in service was done at? If for example you found a nice low mileage car, but it had the running in service at 2300 miles after 16 months, would it put you off? Assuming all else is fine it would at least devalue the car, but by how much, £1k?, £5k?.
I have been reading up on this and it seems that it is mainly a BMW warranty issue, and the consensus is that there is no different oil or anything. I am happy to be educated further on the matter.

I reckon after 11 years, many thousands of miles, several oil changes and all the rest, it makes absolutely no difference whatsoever.

So then it's just a case of whether the buyer wants to use it as a negotiation lever.

If it was an M3 you can always move on, not so easy with a CSL.

Yes mainly a warranty issue, correct oil is the same.

Obviously the oil change was required for a reason so if not done until late you just need to balance this against the cost, slight chance of a problem and resale affect.

Id say that you will have a slight difficulty o moving it on without a price that reflects it but id say 5%?

I doubt it really matters to much now but if you are buying a CSL getting a compression test done is a must and you really need to know if the headgasket has been replaced.

The engine was fitted with running in oil thats why they change it
so soon the warranty from bmw was ok upto 2000 miles as some were late
in getting it done.

... although it's not a 5 minute job, a bit of a logistical challenge and a big ask of the seller

My car for sale at Nick Johnsons had the running in service late, hence the price, but I got a compression test done in the main dealers and it is 100%.

Doesn't exist Mark

"running in oil" can simply mean a straight non synthetic oil.

I know when running in a new engine that's been honed and has new rings it's best to do it on a basic non synthetic oil. It helps the rings bed in. After a thousand or so miles the switch to a performance synthetic / semi synthetic can be made.

Perhaps the above is old tech now but engines haven't changed that much have they?
