I have been using ACES IV from BND Automotive for about 5+ years with great results. Their additive has many befits for me including less valve recession, octane boost & a fuel stabilizer for over the winter.

Just like regular gas their prices have gone up considerably from when I first bought their stuff....a gallon of their product lasts me 2-3 seasons depending on how much I drive....looking on their site a gallon treats 768 gals of gas.

I am due for a purchase soon myself as well and i see he has a new formula ACES IV-P, for higher comp engines & engines that are prone to detonation (like mine is at times)
