Great price for octane booster. I use this in a 2017 Expedition with an Ecoboost engine. I buy cheap gas instead of midgrade and adding this gets me that extra mileage and performance that midgrade fuel would. More than pays for itself.I put the tabs in the filler spout and then put the spout into the fuel filler on the vehicle to get the tabs into the tank and mixed into the gas.

It can also help to clean out deposits beyond the engine but in the exhaust system as well, especially in a high mileage vehicle. It’s an interesting molecule containing molecular iron as a catalyst bound to a fuel solvable organometallic. It also raises octane and creates better combustion as catalyst.

Very good

I was impressed by a video I watched from a YouTuber and decided to try it on my Fall motorcycle trip to the Blue Ridge Mountains. I didn't expect the fuel efficiency and performance I got, even my friends were happy with it. Especially with the lower gas quality at the gas stations up in the mountains, I recommend it. It does work

Not sure about better mileage yet but seems to put pep in my lawnmower

justo lo que necesitaba para subir el octanaje de la gasolina. coloco 2 pastillas por cada 40 litros y todo perfecto

Well this is a first! I've used additives that have had no effect whatsoever, I've used additives that have had good results. But I've never used an additive that has made my car run WORSE than without. Don't waste your money, especially considering there's no returns

This product has improved the performance on my 2 stroke 150hp outboard motor. It claims to raise the octane level on the gas being used. It will planes by boat lot quicker and engine runs and Idles very smooth. Definitely a great octane booster
