Don't hold down the jets longer than a few seconds. If you're trying to climb a mountain or cover lots of distance you want to be holding for the start of your vertical/horizontal and then buffering to maintain momentum while using less fuel. I prefer to do them one at a time, so up and then forwards but do whatever fits your situation.

Also always leave some of your fuel if you can. I need to systematize things so I think of it in chunks, you usually have 4 of them in the tank and if you have the fuel regen module you will effectively have a 5th one by the end of the jump. If there are enemies nearby you need that one leftover to dodge any hammers or ram attempts after you land. For example: Goldrush can make a huge map crossing jump if they spend up to 2 chunks to get air and then up to 2 more for moving forwards but without any leftover it will probably miss the target or lose it's legs. The principle even works on Dredge too; Gain air, move forwards in a short burst and then bit by bit until you can feel yourself arcing down towards the right spot. Small jumps = less chunks or even fractions of them.
