When Should You Fill Your Heating Oil Tank in CT?

The safest rule in winter is to refill before your tank reaches roughly one-quarter full, then adjust based on weather forecasts and your home's usage trend.

Simple refill thresholds

  • Fall and spring: plan a refill around 1/4 to 1/3 tank.
  • Peak winter: refill closer to 1/3 tank for extra buffer.
  • If your household is away often, use a bigger cushion.

Why timing matters

  • Cold snaps can burn fuel faster than normal.
  • Storms may reduce route flexibility and increase delays.
  • Running fully out can require priming/restart service.

Monthly planning checklist

  1. Check tank level weekly during winter.
  2. Review forecast for long cold stretches.
  3. Place your order before urgency builds.
  4. Keep driveway and fill access clear.
