When I first started driving I drove slow bc I thought it would save gas, then I started driving faster when a friend told me you use the same amount of gas whether you drive slow or fast (as long as it’s the same distance), you just would be driving fast for a shorter amt of time and driving slow for a longer amt of time, but at the end you burner thru the same amount of gas. Is this true?

Depends. Pretty much every engine has a peak performance zone – RPMs where fuel efficiency is at its maximum. Lower or higher than that and it will burn more fuel.
Now, the speed that results at that RPM is dependent on what gear you are in. So you might save gas by going faster or slower, depending on RPM, or _both_ assuming you switch gears.
