It takes energy from the engine to make the electricity to break down the water into hydrogen and oxygen gasses, at least as much as the engine gets back minus losses, so no gain.
Also, hydrogen gas mixed with oxygen, unless safely contained is explosive.

Yes, but no more so than propane or gasoline.

I've played around with a couple of hydrogen generators. One of the "by-products" from the generator is water. Water can rust your pistons, cylinders, and exhaust system. To protect your engine's internal parts from rust you would probably have to put some kind of ceramic coating on everything.


To some it's a six pack, to me it's a support group.

When my 2006 30' Gulfstream BTCruiser was new in 2005 I got 9.0 mpg so consistently that I stopped checking.

Two years later I started towing a Honda CR-V and I began checking mileage again. Mpg dropped to 8.5 and was so consistent for about 10,000 miles I again stopped checking.

But I had discovered that I could expect about 100 miles for every 1/4 tank of gas per the gas gage.

This past year of travels (winter trip from Indiana to So Cal and summer trip to the Pacific NW) I began seeing only 85-90 miles per 1/4 tank so I checked mileage again. It has dropped into the low 7's!
Both going West and returning East.

I'm currently at 87,000 miles and I understand a tune-up is not "scheduled maintenance" until 100,000 miles. Does my drop in mpg sound like a tune-up is needed (probably very expensive) or is there something else I might not be aware of? Anyone else having the same experience? I did change tires to Michelin XPS Ribs two years ago, but I can't believe it would lower my mpg.

Engine seems to run just fine. I change oil and grease the zerks every 3,000 miles and have performed all scheduled maintenance. And I weigh before each trip to ensure I'm not exceeding the GVWR.

Any ideas?

I have a 2005 Winnei, Aspect 26A with a Ford V10 and get from 8 to 9.2 MPG on average. If I idle a lot or use the genny for any length of time, the MPG ticks down slightly. I've tried different speeds from 60 to about 68 mph on the Interstate and found that 60 or slightly under does best for me.

I have a very distant relative in Montana that claims he is using the hydrogen/oxygen from water gadget that he has made and gets "REALLY FANTASTIC" fuel mileage on his PU and actually sells the to 18wheeler drivers. I've asked him twice to send me the schematic so I can build one. Naturally I've never received it--It mysteriously gets lost in the mail. Yea, right.

This may be in the wrong place but I've been searching for this topic:

which performs best and gives the best mpg Ford V-10 or the GM 8.1. I understand GM is not making that engine for the class A's anymore but we are looking at used units.

Thanks everyone.

IMHO, you can't have a motorhbome with a V-10 gas engine and expect excellent or even good MPG. It is what it is!!! I agree with there not being a shorage of oil in this country and we should be more concerned about the high cost of fuel. There is something wrong somewhere.

For what reason? Please explain. Thanks.

First post and pitching a product - this seem to me to be a attempt to sell us something.
I saw NO reference to the OP selling anything, only that He had bought a product, & his results from having done so. I didn't see any attempt to sell you anything.
And thanks to the OP for the info & trying to help us all.

Isn't the V10 engine in a lot of pickup trucks?

How does it's gas mileage in these Ford pickups compare with the gas mileage of similar horsepower V8's in Chevy and Dodge pickups?
