[This review was collected as part of a promotion.] The STP Octane Booster has been a solid add-on for keeping my car running smoothly. 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.] STP Octane Booster is the best and cheapest ways to increase my miles per gallon. It runner better feels better . Love the packaging and size of bottle, perfect to carry a few around. I also like that it didn't have a strong smell.
[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 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.

While individual results may vary, its dual-action formula and economical treat rate make it a worthwhile investment for maintaining and revitalizing your vehicle's overall efficiency.
[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.] STP Octane Booster is a pretty good product. My car seemed to run a little more fuel efficiently after the initial tank of gas. It is convenient as 1 bottle treats 15 gallons and you just put it in when you fill your tank.
[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.] 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.
