[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 used cheap octane boost from the dollar store and nothing. I looked up reviews on line and this product had the best price point or $value. I like the small bottles. Here in CA my car pings even with premium because of all the alcohol. Now that I can get fuel outside of CA this product makes regular gas almost premium. Manufacturer reccomends premium for my car.

One cannot go wrong with STP products for fuel additive. I was dealing with possible dirty gas or something going on in the motor and after a few highway uses of this sread apart just so I could figure out what's going on did the trick. I have never been let down by stp products depending on what you're seeking whether it's to get rid of knock or to boost octane to keep engines running clean if you feel like you're getting dirty or too low of a gas octane
