SMB Performance Octane Booster, 12 oz.
The Octane Booster is better then Gas Treatment
I tried other products that were more money, but this stuff really works to improve mileage and gets rid of knocking and pinging...even on my old car

Like all things at Dollar Tree, it's $1! Works as advertised and improves performance.

SMB Performance Octane Booster, 12 ounce
I always have several bottles of Dollar Tree Octane Booster available. My 1986 El Camino runs soooo much smoother using the product. And there is NO WHERE I could purchase it at this high value price. I thank you and my vehicle thanks you!

192,000 miles on Forester with knock at low RPM. Drastically reduced, noticed an improvement.
