How many miles does your 3.0 have?

[sfcl]

2001, 118000 miles (189000 km). Still going strong. Not much problems and failures, a front end restoration at 105000 and a leaking o-ring in the fuel tank which made that the pump sucked air instead of fuel when the fuel level was going low. The original oil is still in the tranny...

Is that healthy?

I decided just to stick to BMW recommendation, lifetime oil. Nothing wrong for the moment, the tranny just works like when it was new (I didn't get it new but I know the previous owner). Hope it will continue...
I was tempted to change the oil a couple of times but I finally chickened reading the forums and all the guys breaking their gearbox sometimes after having changed the oil... Maybe mine is reliable as I live in the islands so no high speed runs. On the othern hand, many gear changes on our small and curvy roads and the weather is hot.
