During the traditional Swedish midsummer party, I was placed next to a man who was a little bit puzzled about the E9 oil change intervals.
The question was: at what date did BMW change the recommendations - for engine oil change - from every 6000 km to 7500 km?
The fact is the following: in the owners manual, up to (at least) April 1973, BMW recommend 6000 km. Looking into the BMW service-booklet, it also indicate 6000 km.
Logically, cars produced after the summer/fall 1973, shld have oil change stickers in the engine bay indicating 7500 km.
However, looking into the untouched engine bay of my late 3.0 CSi from June 1975, the original oil change sticker indicates every 6000 km. The original (from factory/dealer) service-book indicates 7500 km.
Conclusion: BMW changed most likely during the second half of 1973. But don't be surprised if you have a later car with the earlier sticker. Maybe, because BMW had a stock of the earlier stickers to be used up.
The challange wld then be for owners who want strictly original and period correct renovations. Which sticker option to be used?
1. Correct early sticker for the early cars (for sure!)
2. The incorrect early sticker also for later cars - as it came (incorrectly?) from the factory
The only thing which is sure is that cars produced before fall 1973, should have the 6000 km sticker.

PS. the usual heavy rain falls appeared traditionally during the out-door Swedish midsummer festivities. But the "Nubbe" was very nice.
