I've been running this stuff lately on every tankful. I can't believe the difference over 4K rpm. My plugs readings are clean.
104+ is a waste of money. It will raise your octane 5 points. A point is .1 not 1.0. Your are making 91.5 octane not 94. If you want to make 94-95 you need to add a can of torco race fuel concentrate to a full tank.
If you add a can of toroc to 5 gallons of 91 octane you will make about 103 octane.
