STP Octane Booster, Fuel Intake System Cleaner, Bottles, 5.25 Fl Oz, Pack of 12

These are great, I try to use one every other fuel up. Just pop the top and pour before you fuel!

this is by far the best buy on octane boosters on amazon. I have a tuned Turbo Mazda 3 and it KNOWS when it get gas that isn't up to snuff. will pull timing and fall on its face insted of building boost. throw a bottled of this in the tank and most of the time all is well again. Ive been finding the 93 is rarely acutely 93 anymore this helps to make up the difference. the only thing i dont like is the dumb marketing on the bottle.... made from jet fuel. come on marketing team...

Really help with mpg, I’m seeing 1-2 mpg increases on my awd sienna using 87 octane. I usually put 91 octane but gas price is higher now. So I have to put 87 octane and add this each tank.

For 1 of my College credits needed, I decided to actually pick something which had my attention....how about a fuel analysis study.....you will be AMAZED by what I am about to drop on you. Excuse the rather lengthy review, but there are things every driver should know, especially now, with gas prices rising sky high. So, without further ado.... During my analysis, I had to pick 5 gas stations, purchase all available grades of fuel, and then analyze it. Sorry I am name dropping, but this is a must...in no specific order, I chose Exon 711 BP She'll Marathon All 5 had 4 types 87 89 91 97 I would not have known what was about to happen..I mean, who thinks about gas grades...I buy 97, and I'm under impression that's what I am getting....well, this counties best kept secret is...that is not the case....the button you push at gas station, let's say 87, does NOT mean you're getting 87%Octane....what it means, is, you're getting UP TO 87%Octane. Read the fine print as you gas up next time....its there, plain as day. Then ask yourself...when gas delivery happens, how many hoses are put into the ground ? Only 2, not 5 (4 for gasoline, 1 for Diesel). That said, it (Gasoline) goes into a huge tank beneath the gas station, and it is filled with...Gasoline...it's the Gas station Mgr whom adds the Ethanol (required) as well as pushes the little injector button at the 87,91,93 and 97 .....and please remember, these numbers honestly reflect what you are buying, because at 87, you are purchasing gasoline with 10% Ethanol and UP TO 87% Octane....it could be 0 or it could be 50...and at a reputable gas station, it will be very close to 87%...probably like 84 or 85....same goes for all other "grades". Remember, Octane Costs a LOT MORE than Gasoline. The gas station sells the 87 right now here in VA for $3.89/gl....he pays probably $1.25/gl bc he buys it by 10,000 or 15,000 gl at a time....sheer profit...so, if he (owner/mgr) feels like spending extra on Octane, then you're getting some, otherwise, even if you're getting just 10% he is withing the legal limits bc the 87 is "up to"....ok, now that we got this out of the way, and you're probably mighty mad for paying premium price for 93 or 97, and getting probably closer to 50 or 60.....but again, no laws are broken here....now, let me tell you the winners, which will surprise you... 5th place : Marathon 4th place: Exon 3rd place: 711 2nd place She'll And in 1st place with highest Octane ratings was : BP, whom rated 87 at 85, 91 at 90 and 97 AT 97% So, the next time you feel like slicing your wrists whilst paying a whopping $4.59/gl for premium, save that dollar per gallon and buy yourself bottles of Octane Booster....it will upgrade even the lowest grade fuel, and just for the record, it's not the Octane your car needs to run good, it's the heat emitted that makes it run more efficiently...higher Octane gives her that heat....so, you can either spend 80 bucks for a full tank of premium, or buy Octane Booster, add that to the low or mid grade, and save yourself 15 bucks at every fill up. Ok, I'm done chewing your eyes now....and again, the lower ratings are NOT against the law...bc it clearly states.."UP to" in very tiny print below button, and chances are its been rubbed off after a gazillion people push that button every day or week.

Calidad buena

Good product, good price. Would buy again

I usually just put regular in my F-150 5.0 and every once in in a great while I would hear that telltale pinging. My truck is a daily driver and I get a little over 17 miles per gallon After adding a bottle I can't make it ping on regular so it works as advertised with my truck. For fun one v weekend I added 2 bottles of this and 2 bottles of another brand that starts with an L to about 29gal of just bought super and 3gal of regular gas that was already in the tank. The truck ran like a beast. It would downshift sooner than it ever had and it ran better than when it was brand new. After running through all that fuel and filling the tank up with regular it took about 40 or 50 miles before the computer turned the truck back into a lazy slow shifting slacker.

easy to use

Produit conforme et livraison ultra rapide

Great for my old Toyota. Even at this price it boosts ne to thrbictane I want and saves $10 a tank. The engine definitely has more power and is smoother. A very good product.

It does improve the Octane, I use it with Regular gas now on my BMW X3

Great product for high performance vehicles. 10/10 recommendation

Seems some bottles have been relabeled with a different label. Two bottles are not full. Will not buy again very disappointed and questionable if I use the product.
