Here are some wise words from the Maine DEP:
The three leading causes of costly and inconvenient home heating fuel spills include internal corrosion, physical tank damage usually from snow and ice, and preventable overfills. So, protect yourself. Talk to your oil dealer about installing a simple filter protector...and about mounting your tank on a regulation slab. It's worth it.
