On the stock tune/engine in my VS I got less kms and no performance improvement with 95/98, maybe just because I hoofed it harder, but I'm fairly sure it wasn't that. Once I had the generic Mace tune thrown in (among a couple of other mods) suddenly it was more kms and more response, so I only use 98 now as it works out cheaper. And yes it took a couple more cranks to get going on cold starts, but the more octane, the harder it is to burn, hence the protection from detonation and the more requirement for a tune that can capitalise on it. The default Eco tune for lack of a better term is pretty poor.
The Eco seems to be a motor designed around 91 stock, I mean if it was designed for higher octane specifically, there would be a warning to use 95+, or you'd risk detonation. I'd suspect this is the case for most stock (non performance) manufacturers even now as 91 is the most common fuel available.
