Review: Works! - First of all, I have to admit that the product actually seems to work. I currently use it for 4 vehicles. Since one bottle is enough for 68 liters of gasoline, I have weighed it accordingly and calculated on the tank capacity of my vehicles. I originally bought it for my Yamaha Raptor to give it something beneficial, since here in Paraguay we have gasoline with 96+ octane maximum and I have the Big 3 installed on my Raptor. After seeing some videos on the internet where octane boosters were tested in cars on a dynamometer and a power increase of 3 to 6% was MEASURABLE, I thought: I'll try that too. A direct increase in performance I have now not necessarily felt. But the engine runs very well. Good response. Definitely not worse! Next was my Yamaha WR450F. Again, I must say, it definitely does not run worse. But since the bike has endless power anyway, I don't notice any "extreme" boost in power here either. What I have to say though: It has helped to optimize the combustion. The exhaust is much less sooty! Now my last experiment: We have 2 China scooters with 125cc and carburetor technology and the two parts run far from optimal. When cold, they hardly start at all and they smoke non-stop out of the exhaust. Despite several times disassemble carburetor and clean and adjust, nothing could be improved so far - and in the beginning, the scooters ran very well, without problems. Now the miracle! Again, I added the K&N octane booster and wow: after a warm-up and then full throttle and smooth driving for a few minutes no more smoking from the exhaust, no backfiring, no knocking. So far I have ALWAYS had problems with knocking with my scooter. Especially at full throttle and the heat here because the engine is only air cooled... But since I put the booster in I have not had one jerk, stutter, knock or misfire. Both vehicles run SIGNIFICANTLY better. Cold starting works much better now too! So in conclusion I can say, especially with carburetor technology and air-cooled engines and that in warm climates, the octane booster pays off!

## Questions & Answers

**Q: Can i mix fuel cleaner and octane boost? Or will it damage anything?**
A: Octane boost has small amount of fuel cleaner in it. Use 1st, wait at least 60-90 before adding the other.  Pending miles on vehicle, driving habits, along with realistic expectations/results with using product(s); may be 💰👌 or 💸💸💸💸.

**Q: Why does it say "for off road use only" on the back under directions ?**
A: 2 reasons.  1 so the goverment doesnt pull your car into a smog testing area and you fail the test. 2 so you dont blaim it on k&n when you fail said test.

**Q: Can I use this every fill up?**
A: yes

**Q: How much does it increase the octane?**
A: Talking to a mechanic, he said that most gasoline octane boost additives (unless specifically stated) increase the octane rating somewhere between 3 or 4 points.

### ⭐⭐⭐⭐⭐ Great when there is not premium octane fuel around.
*by T***A on September 28, 2025*

This booster works great for vehicles when there is not a station around that supplies premium octane fuel. I have used it in my Audi several times and have had no issues. I always carry one in the car.
