HHO gas

Does adding HHO gas to your car or truck give better gas mileage or is it just a scam?

A blast from the past! It’s been a while since we’ve had one of these (innocent?) questions. HHO is a bogus scam, absolutely!

p.s. - why the double post?

I have been trying to find info on this subject. I just wanted to cover all areas.

It’s a total scam. Not even worth the time to investigate.

“If it’s too good to be true…it IS!”

Forget all the HHO sites, they spout nonsense. Ignoring all the technical reasons, just ask 3 questions:

  1. If it worked, why aren’t the car makers doing it?
  2. If it worked, why aren’t the car users doing it (cab companies, FedEx, police depts., etc)?
  3. If it worked, why aren’t Target/Walmart/Autozone selling them by the millions?

Simple answer - SCAM!

The only way that scam would work is if you violate the laws of physics (conservation of energy).
