[This review was collected as part of a promotion.] This octane booster came in a sturdy easy to use bottle. Under the cap is a safety seal. It easily emptied into the fuel tank. It's designed to boost performance. Not sure I noticed anything immediately but doesn't hurt for reliability!

[This review was collected as part of a promotion.] I added this product to my four-cylinder Toyota pick up about four days ago. I filled up the gas tank drove it about 22 miles. Let it sit a couple days got back in and drove it another approximately 50 miles and it seemed to have a lot more pep acceleration was good. I would recommend this product.

[This review was collected as part of a promotion.] This works as expected! The directions were easy to follow. I simply added it to my gas tank. My vehicle seems to run smoothly now when before it had some knocking. It's convenient and affordable and I would use it again 

[This review was collected as part of a promotion.] This really helped my fuel mileage a lot! I had a little bit of noise before using this, but afterwards I don't hear anything. It's fairly cheap and my car started with no issues. Engine longevity is something that I really prioritize. For reference, I drive a 2005 Toyota Sienna LE. 

[This review was collected as part of a promotion.] I am so glad I tested this product. I didn't realize that a product such as this one could actually save me gas. I normally pump twice a week, on Sunday and then again on Thursday when I a hit the quarter tank mark. However this time around, I only went through half of my tank versus three quarters. My Highlander is running smooth and I just loved seeing the efficient gas savings. This truly saved me some gas money and I am glad I tried it. At the current state of our gas prices, it makes sense to buy this octane booster to get more mileage from my fill ups since the price of a bottle is less than 4 bucks. Which is less than what I am currently paying for a gallon of fuel.

[This review was collected as part of a promotion.] I've been really impressed with this octane booster. It's easy to use, mixes well with fuel, and I noticed smoother engine performance after using it. The throttle response feels more consistent, especially during acceleration, and the engine seems to run more smoothly overall. It's also convenient to keep on hand for occasional use. Overall, a solid product and good value for anyone looking to improve fuel performance.

[This review was collected as part of a promotion.] I recently tried the Gumout octane booster. Driving a higher end vehicle I wondered how it would perform. The bottle is easy to read and instructions are very clear. The product was easy to empty into my tank. I noticed no bad odors while dispensing the product. I did notice a .5 mpg increase while operating my vehicle the same as usual. I would recommend this product to boost your octane levels especially in vehicles that need it.

[This review was collected as part of a promotion.] Easy to use After just a few hours I noticed my car felt more responsive its boost fuel octane and helps reduce engine knocking. With thin liquid consistency that makes it simple to pour neatly into the fuel tank

[This review was collected as part of a promotion.] This Gumout octane booster seems to be doing what it supposed to do and what the label claims. We added this to our 1998 Ford F250 pick up truck on an empty tank and then my husband filled it up. He's been driving it everywhere for the last few days and feels that the trucks performance feels a little better than it did before using this. I would recommend trying this product out.
