Assuming you put the 3 gallons of gas into the oil tank and then added 300 gallons of #2 fuel oil that should sufficiently dilute the gas so it's not a problem. Residential oil burner can burn both #2 fuel oil (what's commonly sold as heating oil) and #1 fuel oil (kerosene) which is a lighter distillate. While not an exact analogy by adding 1% of gasoline to your heating oil you're essentially "lightening" the viscosity of the oil. But you must dilute the gas before running the burner. Firing undiluted gasoline would be danergous
