Speed Demon - 10G
Hijack the tankers in less than 8 minutes in one life in Chapter 6: Overwatch

---

You'll first have to make it to the takers by flying the helicopter and taking out a few enemies along the way. Once you get to the tankers there are three you'll have to hijack. Get close enough to the door so your partners are close enough, then when prompted press X to make them jump across onto the tanker. Do this two more times and the achievement is yours. This must be done without dying.

Use Mission Select: Chase for this achievement
