We Put A Gas Mileage Fuel System Vaporizer To The Test

I am a retired truck driver. The company I drove for had over 1,000 trucks so fuel economy was real important. They determined that driving habits were a huge factor. A gentle foot on the go pedal and coasting, while in gear, made a huge difference. I usually had a gross weight of around 75,000 lbs.and at 65 mph I hovered around 6.5 mpg. When I took my foot off the throttle my mileage meter would go up to 99 mpg. I learned to lift my right foot well ahead of exit ramps, stop signs etc. Going down hill was like a free ride. These tricks apply to cars as well.

I had a customer come to our shop after he had a new exhaust system put on his truck. I asked him about the claims of x% better fuel economy, and x% better performance. His reply was priceless, he said "I'm not sure about any of that but it does make 30% more noise". Haha

Years ago, I installed a special ignition system to give me 35% better mileage, a special carburetor, to give me 50% better gas mileage, and a special intake system, to give me 20% better gas mileage. I drove about 1/4 mile, and my gas tank overflowed!

Good video guys. I'm an old man now but back in the early seventies a buddy of mine and I made a vapor type of system and was getting an improvement of 10 to 20% using the vapor system. After a while we noticed a sludge in the bottom of the tank and asked a Rodchester carburetor engineer what was going on. He explained (as much as we could understand) that gasoline is made up of many chemicals that include hectares, methane and such and each chemical vaporizes at a different temperature. So, although our engine did run on the vapors, the power output, lubrication and other factors prevented the motor from having the same power output as the gasoline when sprayed into the engine through the carburetor (nowadays, with injected fuel systems and especially the ultra high pressure rail systems the fuel is pretty much completely vaporized as it leaves the injection nozzle). There is a reason why engineers get it. They understand research into fields of hydraulics, chemicals, electronics and much more. My hat is off to those brilliant engineers and to the garage guys looking for the better mouse trap. Sometimes, just sometimes, the garage hack invents something the world needs, but that happens very vary seldom. Keep up the good work.

worth the watch just to listen to that engine

These fuel saving gadgets were common in the days before the internet when all you really had was word of mouth. None of the ones I tried 25 years ago worked either. Best mpg results I ever had was with a well tuned carb and keeping my foot out of it. Magic!

thanks for the unbiased info. My favorite conundrum is that we keep building cars that run more efficiently and then packing them with more gadgets that make them heavier and ruin the efficiency we gained.

What I like is that Uncle Tony probably knew that the thing wouldn't work, but he approached it in an enthusiastic and unbiased manner. That's what I like here : just the facts, with enthusiasm. He knows more than all the people commenting added together. Me ? I know nothing.

I always get suspicious of something when the instructions for it are photocopies of photocopies

When I went from 5 days a week to 4 days a week working. I saw an increase of 20% fuel economy in the refill of my fuel tank. Its amazing. And I never had to touch my carburetor. 🤣

Back in the early 80's I was involved in some SAE fuel economy testing on heavy trucks. You needed two trucks, one being the control truck that nothing was changed on. We had removable tanks that were weighed before and after. We found a section of interstate that gave us an East/West and North/South 20 mile trip on one run. We normally had multiple trucks and spent 4 to 5 days on site. Aerodynamic improvements probably gave the largest boost in economy. The advent of fully electronic engines made a big jump, but the biggest improvement was making the driver drive the truck for economy.

Putting high pressure 35 inch tall tires on my 1977 painfully stock F-150. Boosted my gas mileage from 8 miles to the gallon to 12. I also have a first generation modified Toyota Prius that puts out 160 horsepower almost as much as the Ford. I drive it like a sports car and still get 33 miles to the gallon. Plus I got into the car's computer with my laptop. And turned off the traction control. It's the only Prius I've ever seen to do 14 ft burnouts.

Now this is the kind of content I come here for. Uncle Tony cutting out the bs and giving us straight facts!

It went as I was expecting. Seems it's not much more than a vacuum leak in a shipping box.

I remember the JC Whitney catalogs of the 70's, during the fuel crisis of the time. There were many "miracle" fuel saving devices listed that we all knew had to be bogus, but they were fun to look at. I still have a 1973 copy.

Smokey Yunick had a system he created in the early 80's somewhat like this. It has a fuel line that ran through a exhaust heater rail. The fuel going through is heated to around 400 degrees on the way to the carburator. The system was on a early model Pontiac Fiero 4 cylinder. Stock made around 100 HP. After the system was installed it was getting 80 mpg and the engine was making around 300 HP. He had so many irons in the fire he didn't perfect the system. Someone came to him and wanted to by the rights to his idea. He sold it with a verbal agreement that they would follow through on development. Turned out the guy was a shill for a group put together by the big 3. They got the rights to it and shelves it. This was all in Hot Rod Magazine back in the 80's.

An ex-brother-in-law of mine never trusted vehicles that said "dodge" on the front and "ram" on the side. He thought they were instructions.

Hey uncle T been a long time viewer and I’m extremely excited to hear about a fuel mileage build! I’ve never heard of any hotrod channel attempting such a feat!

You need an ✨HHO ✨Generator system to actually improve mileage. An HHO system produces hydrogen out of splitting water with electrolysis and that hydrogen is fed into the air intake. The hydrogen increases combustion which increases horsepower and that reduces gas consumption. The exhaust that comes out the tail pip is also greatly improved with drastically reduced emissions from more through and complete combustion. There is a lot of fakery out there but there is also the holy grail if you keep looking…there are people that have achieved astounding results. Would love to see an HHO system test on this channel. Thanks for all the great content!

I had an 88 silverado 350 long box extended cab and achieved over 1000km on 113 litres, basically one full tank without running out of fuel. I had a K&N air cleaner, Air raid throttle body riser and shorty headers with very conservative driving habits, mostly highway miles to work and back home to city
