Won't point fingers at any post in this thread.However there is a lot more incorrect info in here than correct.

At any one given refinery most tank trucks fill up at the same nozzles as there are three.Red,white,and blue.That designates what octane goes into what tank when you get to whatever station you are going to.Whatever brand of station you are delivering too has it's own blend of a lot of different ingrediants that are punched into the computer and added to the gas as it comes out of the nozzles.Not all fuels are created equal.Some are a lot better than the others.Colder the weather is the better stuff you get in the better brands.Cheaper stations do not put all the goodies in their mix,maybe that's why it's cheaper.

In these engines we have with all the sensors,varitable valve timing,advance or retarding timeimg,depending on engine load,fuel FPPS,10.2 don't really mean we have a true 10.2.If the exhaust valves are not closing until compression has all ready started then that tears the hell out of 10.2.This is why this engine will run on lower octane fuel.Watch as the weather warms up and see how your mpg will drop as the companies go to a hot weather mix.

Some expert said about 93 burning hotter,faster,and cleaner.Nope don't work that way.The higher octane rating a fuel has the slower it burns,it will create more BTUs due to the slow burn,but if you don't have the CR and advance timing,waste of money.Proof of this is by watching NHRA drag races.You have pump gas,race gas,alcohol,and then nitro classes.Nitro has the lowest flash point,but has the highest octane,and it burns the slowest of all fuels.That's why it's so loud and throws out the big flames as it's still exploding as it leaves the exhaust valve all the way out the weed wackers.Nitro cars have to be started on pump gas and then they hit the nitro pumps

The "ONLY" way you can do better by burning 93 octane is to get an ECU programer and increase,timing and some how by pass the varitable cam timing and get the CR up to a true 10.2.But then by doing that you will have wasted all that money for all that tech and research that went into this engine.

Wanna run 93 octane,getta 7psi SC,raise the HP up to 40% and gitter done.
