Tom Ogle Engine Information, MPG – Pros and Cons

In General by Magnus Sellén4 Comments

If you own a hummer or those big SUVs with large wheels, then you are familiar with how gasoline can cause large dents in your wallet.

Now, imagine driving for 100 miles on a gallon of gasoline.

Sounds outrageous and unbelievable?

But, that is what Tom Ogle had in mind when he created a device that replaced the carburetor in many internal combustion engines with one that achieved 100 mpg. Tom Ogle, however, did not live long to enough to commercial his idea and transform the automobile industry.

He died young – at 24 – under questionable circumstances, but the Tom Ogle engine has always generated heated debate among automobile enthusiasts.

How did the Tom Ogle engine work?

tom ogleTom Ogle tried his innovation on a 1970 Ford Galaxie and proofed to the world that a 427hp V8 can do 100 mpg. What was shocking was he tried his invention on the 4,000-pound car. Imagine how much fuel efficiency one could achieve in a lighter car.

Tom Ogle engine used a black box filter instead of the carburetor and fuel pump common in most internal combustion engines. Vaporized gasoline was injected directly into the combustion chambers instead of it being liquid. Many scientists were taken back by Tom’s invention, and his Galaxie was checked for hidden fuel tanks, but none were found.

When pressed further how he came up with the invention, Tom was very candid attributing his fuel-efficient engine to an idea he had while operating a lawnmower. During this time, he accidentally created a hole in the lawn mower. He was forced to use a vacuum line that runs from the carburetor inlet to the engine. He was able to run his lawnmower without the need for a carburetor. What was more shocking was the fact that the lawn mower could run for 96 hours with fuel from its small tank.

This discovery led Tom Ogle to try out his ideas on the automobile engine. However, the engine tanks collapsed without the carburetor, and the car was slow – doing an average of 20 mph at 8 miles per gallon. This changed when he noticed that the gas tank was freezing – like ice cubes – he decided to use heater coils to heat the gas tank. This led to the car doing 100 miles on a gallon.

From there the sky was the limit for Tom Ogle engine. Every investor that he approached was convinced that his idea will bring fuel efficiency and Tom would end up being a billionaire. The only issue was who would take control of the patents – every investor was interested in taking a large piece of the cake. This, however, did not go as planned, Tom Ogle later died under mysterious circumstances, and his invention lost traction with time.

Pro’s & Con’s of the Tom Ogle Engine

  • They produce fewer carbon emissions hence making them environmentally friendly.
  • Cost effective because you spend less time at the fuel station; they make for awesome cars for city drives.
  • Higher resale value; most of the mpg cars hold their value due to a lack of constant maintenance.
  • In some countries, tax credits are awarded to the drivers of hybrid vehicles, in some countries car owners are given incentives to encourage purchase.
  • Most of the models are not considered as stylish as the focus being fuel efficiency.
  • Mpg engine is not that powerful when compared with fuel guzzlers
  • The technology put in place to support hybrid cars is more expensive to maintain than gas-powered vehicles.

What is MPG?

The acronym stands for Mile per Gallon, and it represents how far you can drive a car for a gallon of fuel. MPG is used to judge how fuel efficient a car is. Tom Ogle engine was one of the first to achieve a modest 100 mpg.

Environmentalists use this gauge to know car models that are pollutants. Some cars have achieved great mpg with some hybrid models achieving 600 miles per gallon. Cars with a high mpg are pocket-friendly; some models have even come up that are faster than the fuel guzzlers.

Hybrid cars were introduced to be a cross-breed between fuel and electricity. Users experience a 30 to 60 percent reduction in fuel consumption. With electric cars you need to plug it to a socket for it to charge while with hybrid cars the battery charges as you move.

City or Highway MPG

When you notice mpg being quoted you need to ask yourself whether this is the city or highway mpg. Both are different and will determine the type of car you will purchase. The city mpg puts in consideration constant braking and acceleration while the highway mpg accounts for continuous acceleration hence the figure being higher. The mpg tests fail to account for everyday driving and the fact that there are people who do not know how to effectively shift gears (manual cars).

It is imperative that motorists know how to calculate individual mpg.

Test it yourself

You can do this by resetting the odometer before short and long drips. Fill up the tank and read the odometer again when the tank is almost empty. Mpg will be the figure you get when you divide miles traveled by the gallons consumed.

For example, if you travel for 500 miles and use 10 gallons, your mpg is 50 mpg. This figure is more accurate than those given by automobile manufacturers as it takes into account your unique driving experience.

Mpg cars are pocket-friendly but you have to account for the loss of car power. While we now have some hybrid car models that are super fast most sacrifice power for fuel efficiency. This is the main reason that they are mostly used by city dwellers.

The Tom Ogle engine was revolutionary by consuming 100 mpg. However, hybrid cars where developed that led to a 30 to 60 percent reduction in fuel consumption when compared with gasoline vehicles. Cars with a high mpg are environmentally friendly, and users often earn tax credits from them. You also require fewer visits to the gas station hence making them ideal for city travel. However, the engines are less powerful when compared to gasoline vehicles.

Hello I'm Magnus, the owner and the writer of this website. I have been working with cars since I was 16 and I'm specialized with in-depth Automotive diagnostics. Also been driving drifting for the last 6 years. I'm here to give you answers to all your automotive questions and I hope that you enjoy our content.

  1. I can improve on Thomas Ogle’s system with my experience in the Navy operating evaporators & another system called engine pressure modulation

  2. For any weight of fuel only a fixed amount of energy can be extracted. HIgh MPG means LOW power and it’s not that hard to make an 100mpg engine/power train as long as you accept very limited performance. It’s the application of that power that makes the difference .
    A petrol engine for instance BURNS fuel a Diesel DETONATES it which is a more efficent use of inherent energy content. A Desel also runs at a higher temerature thus making more use of the CARBON content in it’s fuel BUT that higher temperature also results in OXYGEN combining with NITROGEN resulting in very corrosive NOX[ES]. Both NOXes and CO2 are seen by plant life as FERTILIZERS.

  3. When I was doing further research, it said he was cruising at 60 mph when he was conducting the experiment. Whats happens if we make a car like this, then make it Hybrid?
