104 Octance Boost?

Semmessporty

Has anyone used 104 Octane Boost in there Sporty? I run Chevron 93 but was wondering if the 104 would make any difference in performance and gas mileage. Doesn't higher octance run a little cooler?

Higher than needed octane will have little to no benefit other than emptying your wallet. The higher octanes burn slower and will usually run a bit hotter.

not worth it unless you have an ultra High comp motor, the 104 is primarily for exotic autos like Mitsi Evo's and the high end italians

works great if your running 12 or 13:1 compression but for standard 9.2's just a waste of money.

Contrary to how high octane gas is marketed, it only has benefit for engines designed to burn it. High compression engines need a slower burning fuel so it will not pre ignite, Higher Octane rated gasolines burn slower. Pre ignition ping will destroy an engine so it is important to run proper fuel in the engine. However, Over kill on octane simply will do no good, sometimes it can even burn black.

The gasoline we buy these days does leave deposits on the intake valves and on piston heads and heads etc. It is wise to run some Seafoam or Marvel Myster Oil in the tank once in a while. MMO has been around for many years and does work very well. Seafoam is also an excellent product.

Never used SeaFoam, but I have been using MM Oil for over 30 years. It is great.

You could run by the airport and pick up some 110 or 130 av gas.

Thats my point 25 years ago you had 115/145 av gas soldiers use to get some from the air field and run it in there cars. Made a mess of them when they over did it. they use to add a die to it so you exhaust pipes had a red tint to it so they could tell who was stealing it.
I do not even know if you can get 115/145 any more.
I have found no reason to really add any thing to fuel we get today.
