It would be good to remove the oil tank and clean it out.
I've done that by plugging the hose connections and pour in some clean mineral spirits. Then shake it all around for a while as hard as you can to loosen up the junk and mix the residual oil thats still in it with the mineral spirits. You could use gasoline too but you're going to get some on your hands, etc, and it's worse for your health than mineral spirits.
Then quickly pour it out. Repeat the process pouring it out into a clean bucket until it's clean and you don't see any more grit in it.

After all that I like to put some water and TIDE detergent into the oil tank and repeat the shaking and then put a garden hose into it and rinse it out until all the soapy water is gone. If there is water soluble dirt in the tank the mineral spirits won't disolve it and it will stay in there. Doing the water wash after the solvent rinse with TIDE laundry detergent will break down that kind of dirt and rinse it out.

To dry it out after all that hook up a hose from a shop vac that blows air instead of sucking air to it with duct tape and let it blow air through the oil tank for around an hour so all the water inside is evaporated and it's completely dry.

If you want to repaint the oil tank this is a good time to do that. Reinstall it and fill it with oil as soon as possible so surface rust doesn't get started inside the tank.
