This is what my mechanic told me
1) Jap spec car has very clean engine oil and filter. This means those japs they service their car regularly probably before the 25k km bmw recommends. How he knows? because he service a lot of those jap unreg cars for second hand car dealer.
2) mileage can be tampered with but usually they tampered with the cluster's memory but not the lcm memory. modic or any third party software can read the lcm memory. i had mine read, the lcm memory and the cluster memory match so it's all good.
