Octance 99.5

[UsMarine]

Here on the military base I was pumping gas a noticed they change the pump stick from octane 89 TO Octane 99.5 research

Same price.

I never heard of octance 99.5 has anyone heard of it? I did notice my car to run faster :smileysex

I've heard of 101 and 110, but not 99.5

Thats why it is research look it up on yahoo and you get some results.

Probably some blend. To keep the smog down over there. Used to use a methol/Gasohol blend. Good for passing emissions here.


There's a dragstrip 25 miles from my house i used to frequent. The sunoco right before there had everything from 86 octane to 94 on the pump.

Then a seperate pump for the drag strip of 108 octane.

As far as octane ratings, you car will run no faster unless you either up the timing, or you actually need the octane.

Lower octane fuel burns faster and hotter. Only reason you might need higher octane is higher compression, so it burns slower and no dieseling. Upping that turbo wasgate PSI, so more octane is needed to prevent Knock.

Running 108 in a standard car you will really see no difference. The kids used to waste their money on it i used to notice, then go drag moms station wagon!!!

I used to burn 108 airplane fuel from the local airport in my 390 1968 GT500 Cougar...years ago. Man I wish I still had that one! 335hp stock and there was nothing stock on her!;)

A standard blend here in SD is 10% ethanol. 97.5 octane and since the alchohol component isn't taxed and its subsidized to promote ethanol generation, costs the same or less as regular. Wish they made an ethanol blend premium/high octane gas though.

Runs cooler, cleaner and about the same miles/gallon.

Smells "better" than straight gas, kind of a sick sweet odor.
