Jwalsh being level 40 at this point is close to unbelievable, if you think you can be 60 without sppedhacking, .sol editing, anything else, then you're insane. You clearly have some sort of hacking mechanism going. On both comps.
In addition to my last comment, the final machine.. I think the gold gains compared to the oil loss it reversed. You lose oil much faster than gain gold, contradictory to the other two machines (making them better). you do get more when you actually buy the oil, but it's very minimal.
