Save time! Do this achievement and 2 other achievements at the same time by following this method:
First: Before you start any game make sure that you disable Auto Build Units and Auto Abilities (in the Main Menu --> Help and Options -> Gameplay).
This achievement may seem challenging but it isn't! This guide isn't much of a way for you to do this alone, but instead of getting another friend and wasting their time I can tell you how to do this on your own (technically random people doing it for you).
After that is accomplished search for random people in 3v3 skirmish. Now what are you hunting for? Anyone with a ULTIMATE FUEL TANK. If you find anyone with one of those then start the match with them and don't do anything
These are the other achievements you will get:
The Miser achievement in AirMech Arena worth 129 pointsReach Level 10 in any AirMech, and win without purchasing any Abilities.
and if you do another game you can get this one:
The Boosted achievement in AirMech Arena worth 152 pointsWin a match, online or offline, using Boosters, all in Air mode.
(make sure to buy the boosters in the shop and equip it)
