Less Hyperbole Please
For the contributors who make accusations against LU and RR ethics, I would suggest you look at the current long haul industry engine reliability statistics (6 x better than 180 ETOPS requirements), the failure rates of the 747-400 engines from 1989-1992 (I had two), and the current notices concerning PW and GE engines. The conclusions are clear.
BTW: The RR 972 max oil temp is 196 deg C, measured just before the scavenge filter, so an oil temp of 180 deg C is not uncommon.
