I have an interesting question about extended OCIs in European cars. I know the type of oil is different, however...
Are they using longer OCIs because they are taking in account the average lifespan of the engine?
For example BMW knows the car will be most likely scrapped between 200k to 300k miles. You are not taking that Bimmer to 500k miles and beyond.
Therefore the OCIs can be lengthened to allow some wear but still make it acceptable for the average service life of a car.
The same reason we have "lifetime" transmission fluids. Yes, there will be more wear, but if the car is going to be scrapped at 300k, the transmission can make it to 300k without a service, we can make that service optional.
Would love to hear BITOGer thoughts.
