Back in 1967 when I first went into business, a gallon of premium, high octane gas was less than a buck. I was actively racing cars, building race engines, working with 11 others to maintain their races cars (they did some of the prep and maintenance themselves) and we were towing race cars on trailers lots of miles to races. Paying big bucks every month for fuel took a large chunk out of our profits even with the price per gallon as low as it was. Improving our miles per gallon was one of my top priorities.

I was road racing in SCCA, IMSA and ICSCC in short races, competing in endurance races and doing local drag racing for advertisement purposes. Besides wanting to lower the monthly fuel bill, I surmised if I could increase our fuel economy in the race cars, we could go farther between pit stops and that would give us a competitive edge in the endurance races. With those objectives in mind, I started researching and developing different methods that would increase fuel economy, boost horsepower and be environmentally friendly.

I looked at the fuel additives on the market, did testing on most and came to the conclusion that after the price of the additive was factored into the equation, I was trading dollars on most and losing money on others.  And, the largest majority did not improve the mileage.

I replaced the carburetor on our tow van, rejetted it and replaced the automatic choke with a manual choke. That helped a little but I still wanted to increase the race car mileage and the tow car increase was less than I would have liked.

During my research I found that water, if delivered in the right way and the proper amount to the engine, was said to increase fuel economy and horsepower. I wanted to know why it worked that way and delved deeper into my research. Here’s a brief explanation about what I found.

Water slows the flame propagation across the combustion chamber and does that by raising octane ratings. Octane boosters you buy do the same thing with chemicals, chemicals cost money and pollute the environment. Water did neither so I began doing tests on injecting and inducting water into the engine.

After a few dozen different systems were tried and scrapped, I came up with one that was passive, required no switches, valves, injectors or special parts to make it work. The first on the road, in real life tests were done on the tow vehicle, a one ton 350 cid Chevrolet van.

An increase in HP when towing was noticeable almost immediately. The mileage increase was negligible in the beginning but slowly crept up and peaked out after about 1000 miles. I wanted to know what was going on inside the engine and did a combustion chamber inspection using a flexible tool that allowed me to see inside without removing the cylinder head. What I found was almost zero carbon, both hard and soft types.  Internal engine carbon becomes hot spots in the combustion chamber and can cause preignition.

The increase in MPG and HP was due in part to the increased octane rating and the van was a pre-computer model, which meant I was able to advance the timing 10 degrees from the factory spec’s without any preignition/detonation (aka pinging in US English). The fuel was also able to get a more complete burn because there was no carbon to interfere with the combustion chamber turbulence and none in the exhaust system to impede the flow of the exhaust. In the beginning, the mileage was 8 mpg, empty or towing. After all the modifications, including the carburetor change and replacing the automatic choke with a manual choke, I got a consistent 12 mpg towing trailers loaded with race cars and 14-15 on the road and around town. Next was the race car test.

We had a 8 hour race coming up in British Columbia so I installed a MM1 system on the enduro-car, then put the car on the chassis dynamometer to set the mixture, timing and make other adjustments. Even though the engine was clean inside, or I suspected it was, I was able to advanced the timing beyond anything previously possible. When we got to the race course, which I had raced many times before with the same car using the same engine, gear ratio, tires, etc., everything was the same as the last time we raced there , I was surprised at the added HP and lower lap times. So were my competitors.

A couple of other drivers asked, “What did you do? You were never able to pull away from me out of the corners like that before?” I told them I had made a few minor changes and didn’t elaborate. I did notice that there were quite a few “onlookers” from other teams that came to the tech area when we were being inspected for safety and class rules. The car was protested once at Seattle International Raceway but was found to be legal.

I used the system on the tow cars and race cars for 11 years of professional race car driving and did very well with one regional overall driving title and 8 class championships to my credit. I had also put a copy of the same system on our personal family cars with the same increases in HP and MPG.

I retired from racing, sold my businesses and sailed to Hawaii. I put a system on our car while living there and one on a customer’s car who was a drag racer. His performances improved and others wanted to know what he was doing. He didn’t tell them and neither did I. During the Hawaii years, I got divorced and remarried, sold the auto body parts business I had started, my new wife sold her organic farm and we sailed back to the Pacific Northwest.

LM MM1When we were living in NE Oregon, I found a 1949 Dodge one ton flatbed truck in a farmers field. I replaced the old flathead 6 cylinder with a 318 V-8 out of a Chrysler that had a 2bbl carburetor and automatic. After that was finished I had a lot of restoration work done. The power was good but I was disappointed with the mpg. I installed the Mileageman1 on the truck and both HP and MPG increased. While living in New Mexico, where the picture was taken, I met a man whose son had rolled his 240Z. He still had most of the engine parts which included a set of side draft Hitachi SU carburetors. I made a special manifold and put them on the truck. There was a slight increase in both HP and MPG but the biggest bonus was the oohs and awes the truck got when I took it to car shows. Most people thought the carburetors were some type of fuel injection.  We had too many vehicles so I gave the Dodge to a friend who was a Mopar (Chrysler Corp.) collector.

Fast forward to 2002. I was still using the same basic system I had developed back in 1967-68.  In the late 1990s when we were still living in NM, we had gotten a Nissan pick, actually two, from a wrecking yard. I took the best parts and made a nice King Cab plus used parts that were left to make a small trailer. The pickup model was EPA rated at 21-22 mpg. We drove it for a few months before I had time to put the Mileageman1 system on it and were getting the same as the EPA rating. A thousand or so miles after installing the MM1 system our city and country average mileage was 28-29 and on long trips we were getting in the low to mid-thirties. And, we had a significant power increase that allowed us to cruise over some mountain passes in 5th gear that we had had to use 4th and, at times when hauling a load, even 3rd gear. The Nissan is a 1984 and has only a very basic, early computer and I was able to manually advance the ignition timing 12 degrees from factory spec’s. I cover how to manually advance timing on older cars in the MM1 PDF. On OBD2 computer cars, the computer does all the work for you from fuel monitoring to timing adjustments and makes it a lot simpler and easier. How to speed up the computer changes are covered in the PDF.  We also had a VW Scirocco which we sold to a friend and later bought a Chevrolet Aveo to tow behind our motor home.  Both cars got significant increases in miles per gallon and horsepower.

Fast forward again to the present. We sold the Aveo because with three vehicles when touring in the motor home both of us had to drive, one in the motor home towing the Aveo and the other driving the pickup and the pickup was more practical for our lifestyle.

We still have the Nissan, we have 326,456.8 miles on the truck and it still runs great and gets fantastic mileage. During the winter months it gets cold where we live and the water sometimes freezes in the container. If it stays frozen for any period of time, our mileage drops.

Last summer I did some race walking races and kept track of the mileage on the trips. On one trip I had to go over 8 mountain passes, four going and four returning. 35 mpg was the average for the trip.

Even when gas prices are low the savings are significant with the increased miles per gallon and, over the years, we have saved thousands of dollars, maybe tens of thousands. Driving is still fun and the boost in HP is an added bonus.

Since 1967, I have installed MM1 systems or sold thousands of downloads for the systems. Only three customers have ever asked for their money back.

One said he hadn’t received the download. I never got an undeliverable message but refunded his money. Another said it was too complicated. Not two weeks prior I had an 80 old woman email me telling me she had installed it by herself and it was working great. I refunded his money. The last one ordered the PDFs and sent an email the next morning saying it hadn’t increased his MPG or HP. The instructions state that it can take 1000 miles or more to clean the carbon and begin seeing results. I refunded his money.

Recently I read a post on a jeep forum. The question was whether anyone had any information about boosting MPG with water and used my site as the example. There are a lot of “experts” out there but only very few who have ever done more than talk about what they think they know.  Parrots would be a good example.

The reason I send the information out as a download is because of the problems with sending a DVD to Australia, New Zealand, Africa, Europe, Asia or South America. Originally, MM1 was done as a DVD but it proved to be a hassle to send it all over the world. One customer was from an island somewhere in the Indian Ocean. I can’t imagine how difficult that would have been.  What would be the advantage of building something, adding a percentage to the parts, plus the added customer expense for the shipping and handling costs when the person building the unit can buy the parts locally or maybe have most of what’s required on hand?  Mileageman1 was designed as a simple, inexpensive system.  Building it yourself with easily accessible parts keeps it that way.

One Jeep expert also said there was no way to increase MPG in a Jeep. One of my friends has a MM1 system on his Jeep and tells me he gets about 20% increase and more HP.  Another post said,  “I’ll bet he hears from Consumer Reports Lawyers.”  There has never been a reason for Consumer Reports to get involved.

Efficiency increases horsepower.  The more horsepower you get from a gallon of gas, the farther you go on that gallon.  The farther you go on that gallon, the better your MPG.  If you’ve ever tested and kept track of the difference between regular and premium for both HP and MPG, you’ll find the higher octane premium increases both.

The expert also said, “It’s a scam, stay away from it.” I’ve been in business since 1967 and would never have been able to do that if I’d been scamming people.

If you doubt that water vapor can really increase horsepower and miles per gallon, go to wikipedia and search “water injection engines” and read the various articles in that category. You’ll find the Germans were using water in their fighter planes before and during WWll to increase horsepower, extend cruising range and raise the ceiling limits (how high they could fly). They were kickin’ butt until we found out what they were doing.

The Wikipedia information is about water injection which needs pumps, computers and other expensive equipment to work. MM1 is an induction system and requires none of that equipment.  The boosts aren’t as much but, unless you’re flying a fighter, do you need to pay for all that expensive equipment that can break down?

MM1 works with carburetors, manual timing, fuel injection, OBD2 computer systems and OBD1 if the installer understands that system’s short comings.

The MM1 system can be placed under the hood, in the trunk of a car or in the bed of a pickup. It has also been successfully used on stationary engines i.e. irrigation water pumps, etc.

MM1 is versatile, easy to use and install, even an 80 year old with no mechanical background can do it.

Here are a few customer testimonials.

“I can tell you that the mileage after driving about 75 miles went from 18 avg to 22.5 with mainly city driving. That is about a 25% increase. The car also has great power. I always ran premium fuel as recommend by BMW. I put in regular today and the car still runs fantastic.” Mark A. Florida.

This is my favorite: “My friend told me he would help me install your Mileageman1 but he never came by. I put it on my car by myself and it works great. I’m an 80 year old woman and proud of my accomplishment.” Janet B. New Mexico.

“I have put about 1500 miles on my Nissan 1984 300ZX since installing the Mileageman system and have seen a boost in horsepower and increase in miles per litre.” David J. British Columbia.

“I bought a new auto and was disappointed with the fuel economy. Your Mileageman system works well, has easy to follow instructions and the gain in fuel economy has already paid for the download and parts.” James C. United Kingdom

“I was concerned that increasing MPG  by adding water vapor would make my pickup difficult to drive when in Phoenix traffic. I’m glad I decided to take the leap. No problems in traffic and I have gotten good increases in miles per gallon and power both in town and on the open road.” Gary W. Arizona

Unfortunately, I lost a lot of testimonials when I changed website servers.

One customer told me he had flown Corsairs off of carriers during the Korean war and they used water to boost the horsepower. He said they were loaded with so much ordinance that they would never be able to get off the carrier deck without it. He also said he might not have made it back to the carrier if the plane hadn’t gotten better economy.  Another customer told me he was a B52 mechanic in Vietnam and they used water in the jet engines for the same reasons.  Moonshiners, during the prohibition years in the US, used a somewhat similar system to outrun the “revenuers.”

Some years ago, I did a lot of modifications to a friend’s car that he drove on the street and used for “grudge race” drag racing and he really wanted to beat a person he knew. One of the modifications was the MM1 system. During one of our conversations he told me he was driving across the Burnside bridge in Portland, OR when he came to an emission check point, and had no way to avoid it. He said he knew he was going to fail the test. When the inspector came back after analyzing the exhaust he told my friend, “You passed with flying colors. Your car tested way below normal for this model.”  He was doubly happy, the week before he had beaten his rival three out of three at the drag races.

DVD tray

An investment of $19.95 for the downloadable PDF and a small investment in parts to build the Stage 4 MM1 system, probably $10 to $15, maybe less depending on where you buy the parts and what you already have, can save you thousands of $$ by increasing your miles per gallon both now and in the years ahead plus increase the horsepower and extend engine life by cleaning carbon from the inside of the engine.

The PDF is extensive and includes information on a hydrogen system that I used for a short period. I quit using the hydrogen system because, unless I charged the batteries that ran the system using solar power, the draw on the charging system took too much HP, which lowered the MPG in the process, and it was a trade off or loss. I included the information with pictures so you can make up your mind if it is worth the extra time and money to you.
