Review: 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.

## Questions & Answers

**Q: my car is having pinging noise, but it takes 87 octane for gas. can i use this to get rid of the noise?**
A: Yes but purchasing a higher octane gas would be a better idea.

**Q: I have 2019 bmw 430i with an ecu tune installed, would half a bottle for 14 gallon tank be enough to go from 91 to 93+ octane? the tune recommends 93+**
A: So formula is: ((% fuel A X octane of A) + (% fuel B X octane of B)) = Octane of mix. So your case : 14/17=82%, 3/17=18%. Therefore, ((.82X91) + (.18 X110) = 95 Octane
I have a 17 gallon tank and I brought 110 octane and got 91 octane from the gas station 
So 14 gallons of 91 octane , 3 gallons of 110 brought me up to 95 octane. You can plug your numbers in the formula. Hope this helps

**Q: How many gallons of gas does this treat?**
A: approximately 80 gallons of gas

**Q: Can this be used in my jetski. It's a high performance engine and the suggest higher octane which is not available on the river.**
A: Yes. You can use it in your jet ski to boost the power/octane. It is still recommended to use the suggested octane level in your jet ski's manual. If you have any questions, please contact us at marketing@goldeagle.com.
