The most common size oil tank in the Boston area has a capacity of 275 gallons. No matter what it is, 275 gallons of anything sounds like a lot and it is.

As the leak progresses oil will travel up the side(s) of the tank. If the leak goes undetected eventually black icicle-like deposit forms on the underneath of the tank. You may or may not notice an oil smell.
As this deposit grows larger, reddish black spots will appear on the floor underneath the area. Depending on how long the leak goes undetected, an oil stain will begin to develop on the floor.
