A lot of focus on octane in here - which to be blunt, has what exactly to do with the problem these cars are having?
Appears to be much more of a miss on cold weather testing - the bulk of the problems are being reported in cold weather states, and the "recall" used in China noted problems with units operated at temps that were regularly under -4 F and short tripped.
I get that some of you have issues with DI, and even more with TGDI engines. And others have even more issues with the fact that 87 is recommended or allowed with the use of many of these. Yet the use of 87 octane here does not appear to be the issue, so we are making a big deal about it because???
