No, Octane booster raises your octane a couple of points, as in percentace points. As in 93.0 to 93.2. Not at all worth it. If you are FI and need octane, research Tolulene and Xylene on the web. Far more cost effective.

 

just to let everyone know 94 is a myth it pumps from the same tank as 93...and its 10 cents more...sunoco got in trouble thats why its being phased out...a guy that works at the station told me..so you people have been getting ripped...the octane isnt always exactly 93 either it can be more or less but they have to round it off

I checked, it's 94 not 96...checked the one @ 14th and mccowan...

The are no federal requirements that the average octane posted on pumps must be accurate..[or even close]..........all one can safely assume is premium has more detergents than regular.

Contact your State and find out if they test octane most don't.
