Amazingly YES!
By
JOHN,

This turns 87 octane into 93 octane which means higher compression and better fuel mileage. If you can find non-ethanol gasoline, add one of these to your tank and fuel up with the non ethanol. AMAZING RESULTS! You’ll notice you can go quite a long way on that tank. You’ll also notice a little pep in your engine. This is super great for turbo engines!
Bottom Line
Yes, I would recommend this to a friend.
