Made no difference whatsoever..

I wanted to take advantage of the added benefits of my Mustang running higher octane. Even though it can take your typical 87 gas, the torque curve is better with the added octane according to the owner's manual. Not sure if I noticed much of a difference at first but after my 6th or so application I certainly did. So I bought a case and now I do the monthly subscription. I definitely notice better throttle response in 4th and 5th gears. It's like she's ready to roar and what a great feeling it is when the gas peddle is that touchy in a muscle car. I think the cleaning properties took a little time to do their thing and is why I'm feeling the pep. I am a big believer in adding gas treatments every oil change to counter the crap that goes through your injectors. I don't trust gas with ethanol which attracts moisture and causes corrosion. With this product I'm getting true 2-for-1 benefits with the boost of octane and keeping my fuel system clean. Plus it's way less expensive than buying premium fuel which may or may not help with cleaning. This is a no-brainer-must-have product for anyone who needs or is able to take advantage the added octane. Only drawback is it is unknown how many points of octane is adds. It should advertise that is adds X per 10 gallons, etc.

think it works ! LOL placebo effect ?

Works well. Arrived perfectly.
