SHO max octane

[Hutch1]

Can anyone give me any reasons why I couldn't try about 5 gallons or so of 110 octane gasoline in my stock SHO.

It would just give you worse gas mileage because octane has no energy content. It merely inhibits combustion. I don't see any reason it would hurt your car in the short term.

There is a Gas Station near here that sells 110 "Race Gas", I used to put some in my Harley from time to time just for fun. My concern would be most of them still have Lead which I don't think works well in modern engines. As much fun as it may sound "My Two Cents" I would stay away from it, without a tune to take advantage its not going to help so all you can really do is hurt something. LMAO But if your like me you will probably do it anyway.

I have heard a slight increase over 93 the computer will adjust for but you really need a tune to take advantage. And as said leaded gas is a no no.

Ford's website notes the advertised power numbers were on 93 octane. I guess there is no reason to go over this unless you have a tune and lagitamite need for it.

As noted above high octane is a slower burn/resistance to burn. Cetain is how easily the duel ignites.

Yes but computer will adjust to some degree just as it adjusts to lower octane but you really need a tune to take advantage. And seeing how the only thing available close to me is 100 at around $10/gallon it's not with it unless you are doing a track day.

Virginia Speed sells VP ms109 which is unleaded race gas...I have ran a few gallons of that with a regular 93 tune but I also have another tune specifically for that fuel which makes a very noticeable difference

Unleaded race gas really shouldn't hurt your car at all. It won't really help it, but it won't hurt anything except your wallet. Leaded race gas could **** your cats so I would stay away from that. If you don't have cats, I've heard might hurt your O2 sensors but haven't seen anything to back that up, simply rumor.
