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?

Each car has its own spot of highest fuel efficiency. If you go just 1mph, it’s almost the same as idling which just is a waste of gas. If you are redlining the engine in the highest gear, you may be going fast, but you are burning way too much fuel due to air resistance among other things.
Many cars are most efficient at around 55-65 miles per hour. This gets them to their highest gear, but with relatively low rpm’s. The air resistance isn’t too bad at this speed either.
