I think by points in octane is like 0.1. It would be simpler to state what the octane is of the actual fluid in the bottle and work out what it dilutes to when in the fuel. Either case, it will raise octane more for low octane fuel, and less for higher octane fuel. I doubt you can use bulk 91 octane and use octane boost to get into the racing fuel area (100+ octane).
Batteries physically how less energy when cold, so makes sense. Their amp rating and capacity decreases, but they still work just fine if designed for the weather, unless you're in Alaska or Canada or something like that.
What year corolla do you have, which engine? Mine was a 97 DX so it came with the larger 1.8L. 98+ had a completely redesigned engine that I wasn't too fond of. Not sure what was after that.
Ironically, I did look at your fuelly profile when looking at the figures.
My corolla doesn't have much of anything special about it, passenenger mirror delete, grill block, and I did a half engine bay belly pan. The under side was already fairly smooth, I don't think it did much for areo, the grill block might have helped slightly, and the passenger mirror helps maybe a tiny bit. I suspect my mods might be good for 2-4% gains. The biggest effect was driving slower everywhere and getting it in that sweet zone where the timing pulled back. I don't know what trips in that mode or why the max advanced timing is so bad for mpg in that engine, but I wish I knew more about what exactly was going on. Generally advancing the timing gives mpg increases unless it advances too far. Maybe it has a bad knock sensor or something and doesn't know it's going too far.
