Third cheat: Unlimited Fuel

How to get as much fuel as you want and/or not to use any.

Do everything from getting started guide. Now, first you'll learn how to get as much fuel as you want.

First cheat: Lots of fuel

First step: Go to your base to equip your ship. Fill your fuel tanks to the max. If you don't have any fuel tanks, the max would be 10. DON'T LEAVE THE BASE OR THE FUEL MENU!
Second step: Go to cheat engine and scan for the amount of fuel multiplied by 100. In this case it would be 10*100= 1000, so scan for 1000. You'll get multiple addresses.
Third step: Sell one unit of fuel in Ur Quan Masters. Scan for 900 (in our example. Your number might be different) in Cheat Engine.
Fourth step: Double click on single address to lower it into working part of Cheat Engine.
Fifth step:Change the value to how much fuel you want (multiplied by 100) and tadda, you have that much fuel.

You can now sell it or do anything else with it (like using it for travel). But there's better way, the one that doesn't use any fuel tanks because you don't use any fuel to travel. Here's how.

First to Fourth step: Same as above.
Fifth step: Click on freeze by the side of address. The value will not change now, which means that you'll travel for free.

To be safe, unfreeze it when travelling to Quasi-space and landing on the planet(s). Those things always use up the fuel and there's certain risk that the game will crash. Also, make sure you always have at least 20 fuel when travelling to Quasi-space.

That's all there is to it. Have fun.
