Ah, Thanks. That makes sense.

I run 89, 93 around home. When I go on long trips or pulling my boat it's 91 non ethanol, about a 2 mpg gain.

I use 89, that is what the say to use so I do so. It is like 10 cents difference, that is just over 2% more than 87 with gas prices these days, the savings to me using 87 is not worth it.

Higher octane doesn't equal more power. Actually the opposite is true. Octane is simply a chemical that resists pre-ignition. Becuase octane is an additive to fuel, vice fuel itself, the higher the octane, the less btu's available. IMO use a good quality fuel within the required octane rating, and save your money for those mods you want

93 or 94. Not running a tuner yet, so when I do I'll be able to take advantage of it...

Getting discounted gas and have two FI/turbo cars that require 91 or higher makes it a no-brainer. Paid $2.69/gallon for 94 the other day, and filled up two 15-gallon cans after I topped off the truck...
