1. I cant belive it wow

2. Fuel additive company: stonk

3. i did not expect to see that result

4. Start of video, I call horse shit.

   edit: well call me a doodle and skin my snake.

   Still ugliest torque curve on the planet XD

5. This is good science

6. fakin magic?how much did they pay you?

7. Did you warm up the engine with a long drive like you did after additive? Because it seems an engine after a workout has all it's sensors on alert, computer understanding demand, and engine programmed for the workload. If you just drove from home to the shop before additive, it wasn't a fair test because it would favor additive just by contributing normal on-the-fly operation that pre-additive didn't have.

8. Chrisfix, can you do a video comparing performance air filters and even cold air intake?

9. The experiment is flawed in the sense that it only shows bhp increase with the additive in the tank, instead of benefits retained after the additive has run its course.

   The fuel should have been collected prior, with a third used for a dyno test. And then the second third used with the additive. Once the that fuel tank has been emptied then the last third is added. That way you would know if whether the power restored/gained was actually retainable.

10. Ok so now do the test on a twin turbo engine that is TUNED for higher octane needs, which is what these products are designed for.

11. What how is this possible? Unless it's an octane booster and your car turned up the timing with the better fuel. What octane was u running??

12. Good results

13. Can you try some other additives like for diesel fuel injectors or something and show the spray of the injectors before and after treatment? That would be awesome like this video is! 😃

14. Read about what JESUS did this is mine blowing. Can you believe this, did you ever hear of this about HIM

    Romans 10:5/10, c u there
    $$🧐👌

15. Nice video but do you have something for diesel cars thanks

16. Dose he have a receding hair line no offence

17. Good question is what gains in a modified engine would you get. Real modification done externally not just bolt on parts. And at higher compression ratios. Might use this in my modified 12hp k301 in a 1969 cub cadet 126 set up more like the quarter scale pulling tracors and not oem. Easily break the 20hp range at 3000-4000 rpm range I would hope based off your test with oem engine and drive train.

18. Only thing I wonder is if it’s more effective when you put in the additive before the fuel like Chris said it says on the bottle. Awesome video though! Very helpful

19. Going through your old videos and I see a TIBURON lol.

20. in car yes. in honda no. its like mercedes an tractor for delivering pigs cows and shit thats all.

    But cmon man you it will work.. its same as gasoline 95 and 102 or pick 92 and 102 and you will see that you have more power oh wow.. whyyy……………….. aha

21. I'm interested in mpg…

22. Kawasaki susuki vtec vtec vtec vtec bseries bseries

23. This is the closest to a face reveal yet

24. 7:40 yo

25. 6000 RPM VTEC BROOOOOOOOOOOOOOO

26. Just a question regarding this. Is Vtec better than Ecoboost?

27. You most likely changed the air filter or exhaust without us seeing to get the higher HP numbers since you are advertising

28. vtec needs to be lowered in the rpm range. jesus

29. I mix 40 liter diesel with 1 liter gasonline in my diesel car

30. Yes, my AFR was 12:1 and after metal lube, was 12,6:1, so better combustion for more compresion

31. Well good info, because that’s what I have a Honda Civic.

32. 2:44 BRO VTEC VTEC VTEC

33. Here in philippines the taxi use nitro for short lpg vtec kick in 1000rpm go to heaven

34. Your baseline is not correct because you went for a drive before testing the additive / trans and drive train (wheel bearings) temp

35. Did u start out with premium gas in the tank? Or did u just use the Clean Boost max to boost the octane of regular 87 octane gas in the tank? I must know before I buy this stuff!

36. I have no idea if they let off the gas at redline the camera shakes

37. 5 whole horsepower?

38. This looks good. But does it have any negative side effective? Can it affect the engine negative in long run? Does it work well on all fuel quality ?

39. Crisfix i need help i have audi 80b3 1.6 disel but my car out black smoke but no lost oil level i adjust bosch pump but same. What to doo to put adetives or what you sugesstry me ? Or in future can you do video to stop smoke black

40. How much do u put at a full tank

41. Yoda after ketamine increases his Honda Civic horse power with ChrisFixIt

42. Thats retarded.. half an ounce.. id a put half the bottle in and read the instructions if it started misfiring.. i mean youre supposed to add a full bottle of marvel or the other stuff..

43. Cars need tuning and bolt on parts to make more power. 100 octane gas won't even give you more power unless your tuned for it.

44. Let me know what you think. I used Torco booster and all of my plugs turned orange, my gas mileage went for a shit and I had issues starting my car? What happened? Did I hurt anything in my engine and why all the problems? If I quit using booster and stay with premium will that orange shit come off and will I go back to normal? not happy with all the [problems after I starting using this shit?

45. It’s been 3 years and he’s still responding

46. Imagine doing a whole 5 gallon container of race fuel to 87 regular unleaded

47. Hi
