If you own a Hummer or those big SUVs with big wheels, then you know how gasoline can cause big dents in your wallet.

Now imagine driving 100 miles on a gallon of gasoline.

Sounds outrageous and incredible?

But this is exactly what Tom Ogle had in mind when he developed a device that replaced the carburetor in many internal combustion engines with a device that reached 100 mpg. However, Tom Ogle did not live long enough to commercialize his idea and change the automobile industry.

He died young, at the age of 24, under questionable circumstances, but the Tom Ogle engine has always provoked heated debate among car enthusiasts.

How did the Tom Ogle Engine work?

Tom Ogle

Tom Ogle tried his innovation on a 1970 Ford Galaxy, proving to the world that a 427hp V8 can produce 100mpg. What was shocking was that he tested his invention on the 4,000-pound car. Imagine how much fuel efficiency you could achieve with a lighter car.

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

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

This discovery prompted Tom Ogle to try out his ideas on the car engine. However, the engine tanks collapsed without the carburetor, and the car was slow; it averaged 20 miles per hour at 8 miles per gallon. This changed when he noticed that the gas tank was freezing – like ice cubes – and he decided to use heating coils to heat the gas tank. This caused the car to go 100 miles per gallon.

From then on, the sky was the limit for Tom Ogle’s engine. Every investor he approached was convinced that his idea would bring fuel efficiency and Tom would end up being a billionaire. The only question was who would take control of the patents: every investor was interested in getting a big piece of the pie. However, this did not go as planned, Tom Ogle died later under mysterious circumstances, and his invention lost ground over time.

Pros & Cons of the Tom Ogle Engine

Pros
  • They produce fewer carbon emissions and are therefore environmentally friendly.
  • Cost-effective because you spend less time at the gas station; they are great cars for city driving.
  • Higher resale value; most mpg cars retain their value because they are not constantly serviced
  • In some countries, tax credits are given to drivers of hybrid vehicles, and in some countries car owners are given incentives to encourage purchase.
Cons
  • Most models are not considered to be very stylish, as the emphasis is on fuel efficiency.
  • The MPG engine is not as powerful compared to the fuel guzzlers.
  • The technology used to support hybrid cars is more expensive to maintain than gas-powered vehicles.

What happened to him?

What is MPG?

The acronym stands for miles per gallon, and it indicates how far a car can go for a gallon of fuel. MPG is used to assess how fuel efficient a car is. Tom Ogle’s engine was one of the first to achieve a modest 100 mpg.

Environmentalists use this benchmark to know which car models emit pollutants. Some cars have achieved large mpg; some hybrid models reach 600 miles per gallon. Cars with a high mpg are pocket-friendly; some models are actually faster than the gas guzzlers.

Hybrid cars were introduced to be a cross between fuel and electricity. Users experience a 30 to 60 percent reduction in fuel consumption. Electric cars need to be plugged into an electrical outlet for charging, while hybrid cars charge the battery while driving.

City or Highway MPG

If you notice that MPG is being cited, you have to ask yourself whether it is the city or highway MPG. Both are different and determine the type of car you will buy. The city-MPG takes into account constant braking and acceleration, while the highway-MPG reflects the continuous acceleration, so the number is higher. The MPG tests do not take into account everyday driving and the fact that there are people who do not know how to shift gears effectively.

It is essential that drivers know how to calculate individual MPG.

Test it yourself

You can do this by resetting the odometer before short and long trips. Fill the tank and read the odometer again when the tank is almost empty. MPG is the number you get when you divide the miles driven by the gallons consumed.

For example, if you travel 500 miles and consume 10 gallons, your MPG is 50. This number is more accurate than the numbers provided by car manufacturers because it takes into account your unique driving experience.

MPG-efficient cars are pocket friendly, but you must take into account the loss of performance of the car. Although we now have some hybrid car models that are super fast, they sacrifice most of their performance for fuel efficiency. This is the main reason why they are mainly used by city dwellers.

Conclusion

The Tom Ogle engine was revolutionary because it consumed 100mpg. However, hybrid cars were developed, which led to a reduction in fuel consumption of 30 to 60 percent compared to gasoline vehicles. Cars with a high MPG are environmentally friendly, and users often receive tax credits from them. They also require fewer visits to filling stations, making them ideal for city driving. However, the engines are less powerful compared to petrol vehicles.
