Bad gas ?

Just purchased 2016 Allegro Bay V10 gas. RV has been sitting for a long time, very low mileage.
Check engine light on, took it to a Ford dealer and they said it was a misfire on two cylinders, blamed it on bad gas which they said is not covered under warranty. They want 1000.00 to drain the tank.
If I don't they said injectors and other problems will not be covered later.
Should I just treat and run the 100 gallons out and clear light ??
Or should I go along with them. They said they tested the gas by lighting some on fire and it did not all burn.

Thanks

So, you stated that the CEL was on. Did you have any driveability issues, or, just the Check Engine Light? Lets not prop the sky up before it's confirmed that it's falling. Low octane fuel sets the CEL on my F53 every time.
