Real performance in a bottle
I have tried a few octane boost formulations and I have found that 104+ is the first one to show actual physical gains that make a real difference on the road and on the dyno. For the price, even if you never get to test on a dyno, you will notice a huge difference in throttle response and acceleration once the bottle is fully mixed in the tank and running thought the fuel system. Now this is not for flex fuel vehicles, but does make a huge difference in Turbo powered V6 engines and V8 engines, you will be pleasantly surprised.

45 MPH punch
I run a 93 octane tune on my 2017 Camaro SS and a bottle of 104 really perks her up. And bonus MPG which I don’t care about but it tells me my car is burning good fuel. I run this in my 2013 Harley Davidson Breakout as well, same conclusion there. Quality product. I’ve used Lucas, stp, others. I like the 104 the best.

Really works
I have a vehicle that needs 89 octane. At Costco they have 87 and 93 octane fuel. I don’t want to spend extra money on the 93 octane fuel so I just use octane booster with the 87 octane gas. I’ve used other octane boosters but never really felt any difference in acceleration but I do with this product. It’s also more affordable than other octane boosters. The engine really runs good using this octane booster. It’s a really good octane booster that really works and it’s affordable.

Best on the market!
I have used 104 octane booster since I got my first car when I was 16. I'm still using now that I'm 61. I have tried Many other and keep finding out the same thing. 104 is the best on the market. So many buy the more expensive brands because of the big names. But compared to 104 they are garbage. With 104 you get So much more for the smaller price! I just dont understand why it's almost impossible to find in stores. I am so happy that Amazon carries it! BTW, I don't work for them! I'm just a greatfull and a lifetime user of 104!!!

Used for jdm car
If you just recently bought a jdm car this might be in order. From my understanding, other countries uses higher octane than here in the states. The ecu in those countries might be looking for higher octane. I mixed 3/4 of a bottle with a full tank of 91 octane. After doing that, the engine seemed a lot smoother with better performance. Good value.

Great Octane booster + injector cleaner
I use this for my 2008 Mini S,Acura TL,CR-V and FJ and always has been great when used consistently. I’ve been using this since back in the 90’s I had an RX-7 that has hesitation when accelerating and after using this for a month it fixed the hesitation so since then I’ve been using it.
