[This review was collected as part of a promotion.] I used the STP Octane Booster in my older sedan that was starting to show signs of sluggish acceleration. After adding one bottle to a full tank, I noticed a noticeable improvement in performance, especially during highway merging and uphill climbs. The car ran more smoothly, and I experienced a slight increase in fuel efficiency over the next couple of refuels. The packaging is compact and easy to pour without spilling, and there's no overwhelming chemical scent. For the price, it offers great value and a quick way to boost engine performance between tune-ups.

I use it when I want a little extra performance, especially before long drives, and I've noticed my engine runs smoother and accelerates more easily. It's simple to pour in, works with a full tank, and gives me peace of mind knowing it's helping clean the fuel system while boosting octane. For the price, it's an easy way to keep my car in top shape between maintenance visits.

[This review was collected as part of a promotion.] Very easy to use, just remove plastic packaging, remove cap and safety seal, and insert into your vehicle's tank. The bottle has a long slim neck, so it's very easy to add to your gas tank. I honestly didn't notice any sort of scent. This is like giving my truck and energy drink.

[This review was collected as part of a promotion.] I used this before a trip in my truck. I wanted to be sure that this would be a smooth trip and I could take advantage of all the MPG I could get. This is easy to use and just needs a small funnel. I've used this brand many times before and feel like this is a quality brand that I trust for my vehicles. Overall, I feel like this helped boost my MPG for the trip. The bottle is slim and easy to hold and add to any type of vehicle.

[This review was collected as part of a promotion.] Okay, so I recently tried this stop octane fluid, and here's the deal! First off, I was a bit skeptical, but my car 🚗 was pinging like crazy, so I had to give it a shot. I poured it in, and within a few miles, the engine noise started to fade, which was a huge relief. The engine feels smoother, and I've noticed better acceleration now, making my drive so much more enjoyable. I'm super happy with the results, and I'll definitely be using it again; overall, it's a thumbs-up from me! 👍 #OctaneFluid #CarCare #EngineBoost #SmoothRide #CarReview #influenster

[This review was collected as part of a promotion.] The packaging came good and my dad helped me put this in my car which did in fact help. We did this to my car before heading to New York for the day. We noticed that my car was driving better with this. I would recommend this.

[This review was collected as part of a promotion.] Thank you STP and Influenster for letting me try this product. I have used it for some weeks now and although I wouldn't know for sure but I do feel my car is running more smoothly. I think it works well on my car and if I see the same improvement in the next couple of weeks then I'll continue buying it.

[This review was collected as part of a promotion.] The packaging came good but that's pretty much it, I tried it on my Chevy Silverado Z71 and I didn't see any difference in longevity with the gasoline I have and added as well, I would say the value is pretty good but I don't see the use of it, it doesn't have much scent either but I don't see any affectance.
