"I've got filters," Cloud informed him helpfully as he dragged his Fenrir closer to Aaron's position and took the nozzle from him, nodding his thanks. After all, from where he came, if your vehicle didn't have a filter, then you're pretty much dead. The fuel in that place was...well, Cloud wouldn't say it was nasty, not when Fenrir ran fine with it, but he was willing to bet that it wasn't as -- borrowing the man's word -- refined as say, maybe the stuff he uses or the more popular and unhealthy mako energy. That was some really good stuff.
But he wasn't about to kill the planet for a road trip or two.
"Actually," the nozzle just inches away from Fenrir's gas door (which may conveniently be found overshadowed by his left compartment), Cloud turned to Aaron and asked, "what is it made of? Your gas?"
