I have an older car and I want to increase it's fuel efficiency while boosting the horsepower. Is there any way I can achieve both?
user
Your goal of “more power, less gas” is a common problem that many modern automobiles are designed to help with.  But it’s tricky, because of how physics and the laws of thermodynamics work.
assistant
Well, I have no idea what thermodynamics are, I just want to make the car less sluggish and use less gas.
user
Unfortunately physics and the laws of thermodynamics are at the root of how all cars work, and how human civilization works in general.  Modern cars use a combination of engines, transmissions, and brakes that achieve what we want, so they can be both powerful and efficient.  It’s an advanced technology that humans have designed.  But the basic physics is still the same.  I’m not sure what level of explanation you’re looking for.
assistant
It doesn't have to be super scientific. I just want to be able to improve the power and get a little bit better mileage out of my old vehicle.
user
So you want to explain how cars work, and be able to increase horsepower and improve gas mileage at the same time?  That’s not possible.  You’re asking for a sort of “magic” that we know doesn’t exist.  Does that help?
assistant
Not really. I know how cars work. That is not what I am asking. I just wanted to know how to increase the HP and the gas mileage of my older car. That's all.
user
OK, I think I see what you want.  So you’re looking for a small power- and efficiency-boost?
assistant
If all I can get is a small boost, then yes. I'll take what I can get at this point.
user
Alright, I know a way to do it!

Can I ask you a few questions to help me better understand what you want?
