Yes, fair enough. But the immediate suggestion elsewhere that buying tractors helps Zynga is false.
I admit it, I'm level 40 - have been playing for a long time. I've never spent any money on it. You do get given FV cash occasionally on levelling up, but not enough to make a difference. I think I have 15 neighbors or something. I do my wife's farm too, which has helped with various bonuses, etc.
Yes, the fuel thing is frustrating, since a tank is nowhere near enough to harvest/plough/seed, and you are reduced to thousands of clicks. However, some of the "holiday gifts" still available contain 1 or 5 tanks of gas, and next week is "free fuel week", whatever that means. No doubt of course as a promotion to encourage people later to buy it.
