That thread is only valid for the 350, isn't it? Correct me if I'm wrong, but that damage is caused by pre-detonation due to the lack of a knock sensor (Or mapping to use 95 RON). You won't get this same damage using 95 in a 370... but it won't be as powerful or fuel efficient. There is surely no danger to the engine from using 95 as the 370 is setup to use this as well as 98.
Happy to be told that I'm talking horsey poop. There seems to be a lot of scaremongering around this point which isn't necessarily valid for the 370. Don't get me wrong, I wouldn't use 95 if I had a 370, but doing so wouldn't cause any short or long term damage?
