Son swears by it!

cindym234_2171 August 9, 2025

[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.

Easy to use.

carolynjordanself_9734 June 22, 2025

[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.

A quick, affordable boost that noticeably improves

pamelaf_1285 June 25, 2025

[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.

A smoother run

wolfkatreviews_1322 June 17, 2025

[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.

It worked for my car.

body4mind_5019 June 20, 2025

[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.

Smooth ride

bunnyx520_6185 July 14, 2025

[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

Good

lennie_rr_4530 June 19, 2025

[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.

Doesn't work for me!

ramcese_8291 June 23, 2025

[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.
