I'm in my 70s now, and I remember when I was a child I read car magazines, because cares were the cell-phones of the day.

Each year the car manufacturers participated in the "Mobil Economy Run".
https://en.wikipedia.org/wiki/Mobil_Economy_Run

Mobil Economy Run was an annual event that took place from 1936 to 1968, except during World War II. It was designed to provide real fuel efficiency numbers during a coast-to-coast test on public roads and with regular traffic and weather conditions. The Mobil Oil Corporation sponsored it and the United States Auto Club (USAC) sanctioned and operated the run.

I remember an interview with a driver who said to get maximum fuel economy he (1) accelerated slowly, as if there was an egg shell between his food and the accelerator, and (2) anticipated braking by taking his foot off the gas pedal and coasting as much as he could. He added that when you use the brakes, you convert fuel you used into nothing but useless heat.

For my work, I use the smallest minivan that will hold the gear necessary for me to do my job. I drive them for at least 200,000 miles and only get a new one when something happens that makes me question their dependability.

So I adopt these driving habits:

• I accelerate slowly, almost painfully slowly until I got used to it. To be courteous, I do this in the right 'slow' lane
• I anticipate braking: When the light turns red up ahead, I immediately take my foot off the gas. In my normal driving roads, where the speed limit drops, I know exactly where to take my foot off the gas so I can get to the lower speed without using the brakes.

Results:

• I get an additional 5 miles per gallon over what the car is rated at. With a 20 gallon tank that means an additional 100 miles with the same amount of gas. That saves me money, and spews out much less greenhouse gas out of the tailpipe
• Bonus #1 - I get about 100,000 miles on a set of brakes
• Bonus #2 - My last minivan went >200,000 miles and never needed a quart of oil between changes

Note:I immediately got about 3mpg better, and as I learned how to do this better, I increased that to at least 5mpg better than the vehicle's rating.

So do I get where I want to go slower? Yes. But not enough to make a difference. In an cross-town trip the difference is usually about 5 minutes. So I leave the house 5 minutes earlier. At the price of gas, that's pretty good pay per minute of my time.

So I challenge others to try it, and spread the word to others who care.

Since I work in the oil and gas industry, I do my best to consume as much as possible. Any tips on lowering my fuel mileage?

I have heard that many in Texas have routed their exhaust pipe into the passenger compartment. It does not lower the fuel milage, but it does result in the loss of the few brain cells required to do the math to know what your mileage is. A side benefit is that you also lose the ability to troll.

Well, we wouldn’t want that. I don’t have a lot to spare.

I read an article on the things that your mechanic wants you to do.
1) Jackrabbit starts
2) Hard braking
3) Don't change the oil

Why? All these things bring you back to the repair shop.

So if you follow my advice, not only do you get 100 extra miles per tankful (and those dollars in your pocket) but your car will not need repairing as often (more dollars in your pocket).

If course if you work for the oil company or just like to troll, I guess you won't heed good advice.

Some people swear by running an engine on gasoline vapors. It might all be just a bunch of snake oil. I haven't personally tried it. I will post two different views on it below, one with real-life proof, and the other with claims. It might help you if it really does work. If you try it, let us know how it goes!

Proof (The best, most convincing video from a reputable poster, with believable results): https://www.youtube.com/watch?v=IuGWHfWqWtg

Claims (not super convincing but whatever): https://www.youtube.com/watch?v=58IkmPK6ikc

Hope this helps. It may not, but it IS a cool idea. )

Carburetors and fuel injectors convert small quantities of liquid fuel into a fine mist or vapor.

I don't know if it's true or not, but I read a long time ago that if you keep your gas tank half full or more, less water condenses in the gas and it gives you better gas mileage.

I do know that if you accelerate very slowly and coast when you can so that you apply the brakes as minimally as possible you can get 100 miles more per tank. That's a lot of gas not polluting the planet.

I've done that on 4 cars and beat the EPA gas mileage by that amount on every one. It's also easier on the cars so they need fewer repairs.
