I really need to get into the pouring kerosene into smaller bottles with a pretty label and charging $250 a gallon business.

I think all you need to do is duct tape some magnets to your fuel line , then hold on because of all that new performance !

I got 15 more HP when I installed my K&N air filter. My butt dyno confirms this.

Basically HP is a function of fuel air mix, compression, and proper timing.

That shit you get in bottles does nothing except line someone's pocket.

Octane-rating of naphtha is 58-66 depending upon ratios of light vs. heavy naphtha. So not good for improving performance. Maybe only good as cleaning solvent. Even if it did boost octane-rating, you'd still need to replace pistons to increase compression and re-program ECU to get more ignition-advance in order to take advantage of higher-octane.

Pure snake oil!

When I was about 8 I spray painted the STP logo on my dads yellow brick garage wall. Got quite a beating for that one!

They’re pretty common in the MidWest where I grew up.
