We cut down a tree in March and our neighbor is constantly pouring gasoline and oil into the stump. This is very frustrating as I have small children that like to play on the stump. Anyway, the stinkin' stump is showing no signs of dying. So, hopefully, you're trees will be just as resiliant. I don't know if there is anything you can do, if the gasoline has already soaked into the soil. Maybe you could flush it out with lots and lots and lots of water? Then again, that might just encourage the shrubs/trees to drink up on a gas/water brew. I'm sure someone more knowledgable than I will be around to shed some light on the subject.

If it's regular gas, it will probably go away, as mentioned above.

But, was it mixed fuel / oil like for a chainsaw or weed eater?

If that's that case, you might want to eliminate the contaminated soil.

And, some professional landscape supply places sell activated charcoal which may be useful. Especially for a pesticide spill or over-dose in soil.

You local golf course maintenance department should be able to tell you where to get it. It's well known in the greeens care industry.
