[QUOTE="mastwolf, post: 11230921, member: 26424"] I think it had something to do with BP holding out as long as possible to do the whole 10% ethanol in the fuel. You are all way over thinking this. Stock tunes = Relativity safe on all fuels (87 -93) Ford will recommend "Premium" notice how they dont say "93" because they know In a car that was designed around a goal of "412 HP SAE" they used Premium 93 fuel. But they also know that Joe Blow will go and put 87 in it, so thats why we have Knock sensors that ADD timing into the mix. The spark will start out at a mid point, and if there is 87 in it, and it knocks, it pulls some, if not, it will add it till a certan point, ether A) it sees knock or B) it reaches the max alowed spark. Now there are lot of other things that go into play, 87octane on a hot day or nice cool day, location and altitude have alot to do with it. 87octane in FL might withstand different timing than in Colorado, there for making different power.
