Buc-ees! mmmmm jerky.Though mine is an EcoDiesel, my wife Subaru Forester takes 87 octane, but I like to throw in the 91 plus octane fuels every two to three fill ups because I find the higher octane fuels tend to help burn off a lot of the gunk in the engine.
There's a buc-ee's one city over from us, and I go there once a month and load her car up with the ethanol-free blue pump, it comes out to like 93 octane I believe, but with no corn in it. Amazing for the engine, sucks for the wallet, but it's still cheaper on average than diesel fuel around here. Her car doesn't seem to respond too much differently to it, but last time we took it to the dealership for a warranty repair on the engine, they said that the engine looks meticulously maintained. And even asked me what I have been putting in it. I thought they were being smart, but I've also heard that the higher octane helps burn off a lot of the gunk that the additives clean off, just add a more efficient level.
Better burn; cleaner engine, less corn; cleaner engine, cleaner engine; longer engine life, cleaner engine; less serious maintenance, less serious maintenance; lower maintenance cost.
You could dump any number of additives in there and probably get similar results, but a lot of the additives I've read on a older engineering forum years ago, basically just add a bunch of lubricants which the gasoline already has in it, and increases the octane so it gets a better burn. But you're adding like 16 oz to 18 to 23 gallons of gas depending what make and model you have. It's not going to make a huge difference, not quite like adding 18 to 23 gallons higher octane fuel.
If you want it save on cost, at minimum I would do every third or fourth tank with higher octane fuel. Just my personal preference, I'm no chemical engineer.
EDIT: I should probably note the Subaru Forester she has is a 2.5L non-turbo engine
I was in GA for work and stopped in Buc-ees, man, what a breakfast I had! Two burritos and a sandwich and giant freaking soda! Then I brought back to the office a bunch of beef jerky to share. Good stuff!!!!
